Material selection is based on pressure, temperature, process media, corrosion conditions and customer specifications. Material traceability and supporting documentation can be maintained as applicable to the order and product requirement.

Manufacturing, Inspection & Testing

Quality is integrated into the DELIXIN-LOK manufacturing process. Components are produced using precision CNC / VMC machining and controlled manufacturing processes, followed by applicable dimensional and functional inspection.

Our quality-control activities can include incoming material verification, dimensional inspection, thread and connection verification, surface-finish inspection, 100% visual inspection, assembly checks, hydrostatic testing, pneumatic testing, functional testing and final inspection, depending on the product and agreed inspection plan.

Pressure testing is performed according to the applicable product design and customer requirement. Product ratings are not treated as universal values: working pressure depends on material, temperature, tube wall thickness, connection type, valve or fitting design and the lowest-rated component in the assembled system.

DELIXIN ENTERPRISES operates under an ISO 9001:2015 Quality Management System, supporting consistent processes, quality control and continual improvement.

Connection, Material & Application Engineering

For critical applications, DELIXIN-LOK emphasizes complete-system compatibility rather than component selection by size alone. Engineering consideration is given to fluid or gas compatibility, operating and design pressure, operating temperature, tubing specification, corrosion allowance, vibration, installation environment, connection type, seal / packing selection and required inspection documentation.

Technical Specifications & Product Selection Parameters

DELIXIN-LOK products are selected and engineered by considering the complete pressure-temperature boundary rather than pressure rating alone. The actual allowable working pressure and temperature depend on the product series, body material, connection size and type, tube specification, seat, stem packing, O-ring / seal material, process media and operating conditions. Where several components are assembled into one system, the rating of the complete assembly is limited by its lowest-rated component.

Connections: Available connection options include DELIXIN-LOK Double Ferrule Compression Tube Ends, NPT Male / Female, BSP Male / Female, BSPT, Socket Weld (SW), Butt Weld (BW), JIC, SAE, Flanged connections and customer-specified end connections. Fractional and metric tube-end connections are available for applicable fitting and valve families. Thread form, sealing method and mating-component compatibility are verified according to the selected product configuration.

Configurations: Product configurations include Straight, Angle / Right-Angle, Male- Female, Female Female, Male- Male, Union, Bulkhead, Elbow, Tee, Cross, Reducing and Adaptor arrangements, depending on product family. Valve configurations include 2-Way, 3-Way, 4-Way and 5-Way, together with panel-mounting, union-bonnet, single-bonnet, round-body, 3-piece and application-specific designs. Instrument manifolds are available in 2-Valve, 3-Valve and 5-Valve arrangements including T-Type, R-Type, H-Type, remote-mount and customer-specific process / instrument interfaces.

Seals, Seats & Packing: Sealing materials can include PTFE, reinforced / filled PTFE, FKM / Viton-type elastomers, NBR, EPDM and Graphite, subject to product design and compatibility with the process fluid, gas and operating temperature. Metallic seating or metal-to-metal sealing can be engineered for applicable valve designs and services. Seal selection must be confirmed against chemical compatibility, pressure, temperature, permeability, cleanliness and service-cycle requirements; therefore, no single seal material is considered suitable for every application.

Working Pressure Range: DELIXIN-LOK standard and engineered product families can be offered in nominal pressure classes including 500, 1,000, 3,000, 6,000, 10,000, 15,000 and up to 20,000 PSI, depending on product series and configuration. Typical needle-valve designs are available in 3,000 / 6,000 / 10,000 / 15,000 PSI classes, while applicable instrumentation manifold designs can be supplied up to 6,000 PSI. Higher-pressure product selection requires verification of body design, end connection, tubing, wall thickness, material, sealing system and operating temperature. Published or quoted pressure values apply only to the specifically identified DELIXIN-LOK product configuration and must not be treated as a universal rating for every size or material.

Temperature Ratings: Temperature capability is determined by both the metallic pressure-containing components and the selected seat, O-ring, gasket and stem-packing system. DELIXIN-LOK products can be configured for low-, ambient- and elevated-temperature service using application-appropriate sealing and packing materials. PTFE, FKM / Viton-type, NBR, EPDM and Graphite systems each have different service-temperature and media-compatibility limitations. Accordingly, the exact minimum and maximum temperature rating is specified series-by-series and configuration-by-configuration after reviewing body material, seal / packing material, process media and pressure requirement. Elevated temperature may require derating of the allowable working pressure.

Body & Wetted Materials: Standard and optional pressure-containing / wetted materials include SS304, SS304L, SS316, SS316L, Carbon Steel, Brass, Duplex Stainless Steel, Super Duplex Stainless Steel, Titanium, Monel, Inconel 825, Hastelloy and SMO 254, depending on product family and application. Material selection considers corrosion resistance, mechanical strength, operating temperature, process-media compatibility and project specifications. Special-alloy manufacture can be reviewed for aggressive chemical, offshore, marine, sour-service and other demanding environments.

Tube & Fitting Compatibility: For double-ferrule compression systems, correct selection of tube OD, wall thickness, material, hardness, dimensional tolerance and surface condition is essential to reliable sealing and tube grip. Fitting and tubing materials should be selected as a compatible engineered combination. The allowable system working pressure must never exceed the rating of the tubing, fitting, valve, threaded connection or any other lowest-rated component in the assembly.

Pressure-Temperature Engineering: DELIXIN-LOK does not treat maximum pressure and maximum temperature as simultaneously applicable universal limits. As operating temperature increases, the allowable pressure of metallic components may require derating, while soft seats and elastomeric seals may impose a lower temperature boundary. Final product selection is therefore based on the combination of design pressure + design temperature + media + material + connection + seal / packing + tubing specification.

Application-Specific Selection: For critical service, customers can provide fluid / gas name, concentration where applicable, normal and maximum working pressure, design pressure, normal and maximum temperature, connection size and type, tube OD and wall thickness, body-material requirement, seal preference, flow direction, cracking / set pressure where applicable and required inspection / certification documentation. DELIXIN ENTERPRISES can then review the suitable DELIXIN-LOK configuration against the stated operating conditions before manufacture or supply.

Pressure-Temperature & Seal Selection Note

Pressure and temperature must always be evaluated together because packing, seals, end connections, tubing and body materials can change the allowable rating. DELIXIN-LOK therefore treats the values above as selection ranges only. Exact ratings should be released through the applicable product datasheet after design verification.

For engineering selection, DELIXIN ENTERPRISES should obtain at minimum: product type, process media, concentration where relevant, normal pressure, maximum/design pressure, normal temperature, minimum/maximum design temperature, connection type and size, tube OD and wall thickness where applicable, body material, seal/packing requirement, flow direction, set/cracking pressure where relevant, quantity and required inspection/certification documentation.

Recommended Technical Datasheet Format

For each DELIXIN-LOK product series, the final product datasheet should separately publish: Model / Series, Product Description, Configuration, Flow Pattern, Nominal Size, End Connection, Orifice / Cv where relevant, Body Material, Wetted Parts, Stem / Ball / Spring Material, Seat, Seal / O-Ring, Packing, Maximum Working Pressure at stated temperature, Pressure-Temperature Derating Table, Minimum / Maximum Temperature, Testing Requirement, Cleaning Requirement, Material Traceability, Dimensions, Weight, Ordering Code and Available Options. This avoids presenting one pressure or temperature value as applicable to every configuration.

DELIXIN-LOK products are intended for demanding applications across Oil & Gas, Refineries, Petrochemical, Chemical Processing, Pharmaceutical, Power Generation, Fertilizer, Process Plants, Marine & Shipbuilding, Automobile, CNG / Gas Systems, Metro and general engineering industries. Products for nuclear, aerospace or other safety-critical services are supplied only when the specific product design, material, testing, documentation and applicable project requirements have been reviewed and agreed for that service.

Typical applications include instrumentation hook-ups, pressure and differential-pressure measurement, analyzer systems, hydraulic power units, process-control lines, gas distribution, sampling systems, chemical injection, utility systems, equipment skids and OEM machinery.

Custom Engineering & OEM Supply

In addition to standard products, DELIXIN ENTERPRISES supports custom manufacturing according to customer drawings, samples, datasheets and project-specific technical requirements. Material grade, pressure class, end connection, dimensions, sealing arrangement, marking, inspection and testing requirements can be reviewed against the intended application before manufacture.
