Technology

Engineering For Precision. Built to Last.

Our valves, regulators, and gas control components are manufactured through a tightly controlled 12-stage process that ensures performance, safety, and reliability — every time.
12-stage manufacturing process for gas cylinder valves and regulators

Engineering Precision

The 12-Stage Manufacturing Process

Material Selection & Traceability

Only certified brass, stainless steel, and aluminium are used, with each batch tested and tracked through heat-lot traceability.

Heat-lot traceability and incoming material inspection for gas valve bodies Brass / stainless bar-stock cutting and sawing for C10 cylinder valves Material test certificate review and batch tracking for regulator components

Raw Material Selection & Forging

Incoming materials are verified for chemical composition, hardness, and mechanical strength, ensuring compatibility with specialty and calibration gases.

CNC turning of valve bodies and regulator housings for calibration gas service VMC milling of precision features for gas regulator assemblies Precision drilling, reaming, and port creation for leak-tight flow paths

Precision Machining (CNC/VMC)

Critical components are produced on CNC turning centers and VMC machines, maintaining tight tolerances for threads, sealing faces, and flow passages.

Thread cutting and tapping of C10 inlet and outlet connections Deburring and edge-rounding of sealing faces for gas valves Seat lapping and surface-finish control for leak-tight valve closure

In-Process Quality Checks (SPC)

Statistical Process Control (SPC) checks are performed at machining stations, ensuring consistency across high-volume runs and custom parts.

ISO 9001 certified valve and regulator manufacturing facility

Surface Finishing & Cleaning

Components are deburred, polished, and cleaned in controlled conditions to remove machining residues — essential for leak-tight gas service.

Ultrasonic cleaning and solvent degreasing of regulator components Controlled drying and particulate control prior to clean assembly

Sub-Assembly Preparation

Parts are organized into clean assembly cells, with torque/thread control applied to avoid damage and ensure proper sealing.

Automatic on-demand regulator for calibration gas cylinders

Assembly of Valves & Regulators

Technicians assemble valves, regulators, and flowmeters using calibrated tools. Clean benches prevent contamination of sensitive sealing components.

Pressure & Leak Testing

Each unit undergoes hydrostatic (up to 15,000 psi), nitrogen leak, and pneumatic tests to guarantee leak-tight performance.

Hydrostatic pressure testing up to 15,000 psi for cylinder valves Nitrogen leak testing and pneumatic pressure verification for regulators Proof and burst testing on hydropneumatic press for safety validation

Functional & Flow Verification

Regulators and flowmeters are tested for flow accuracy, repeatability, and stability across setpoints, ensuring calibration-grade reliability.

Flow calibration and verification of fixed, dial-a-flow, and vari-flow regulators Functional testing of demand flow regulators with instrument draw profiles Pressure decay and seat leak tests for C10 valve sealing performance

Proof & Burst Testing

Random samples undergo destructive testing, including burst and proof pressure tests, validating product safety under extreme conditions.

Final Inspection & Documentation

Every product receives dimensional checks, visual inspection, and performance validation. Inspection records and compliance certificates are supplied on request.

Vari-flow regulator C10 inlet variable flow control

Safe Packaging & Export Readiness

Products are packed in eco-friendly, CFC-free protective trays with full export documentation (COC, test reports, HS codes) — ensuring safe delivery worldwide.
