High-Pressure Cylinder Valve Types
High-pressure cylinder valves are critical components used to control, isolate, and safely release gas from pressurized cylinders. They are designed to withstand high pressures and are widely used in industrial, medical, laboratory, and specialty gas applications.
1. Oxygen Cylinder Valves
-
Designed for oxygen service
-
Oil- and grease-free construction
-
Brass or stainless steel materials
-
Comply with CGA / DIN / BS standards
2. Nitrogen Cylinder Valves
-
Used for nitrogen and inert gases
-
High pressure rating (up to 300 bar)
-
Available with handwheel or knob operation
3. Hydrogen Cylinder Valves
-
Designed for flammable hydrogen gas
-
Leak-tight sealing with special materials
-
Often fitted with burst discs or PRDs
4. Helium & Inert Gas Valves
-
Used for helium, argon, neon, krypton
-
Smooth flow control
-
Compatible with laboratory and industrial cylinders
5. LPG / Propane / Butane Cylinder Valves
-
For liquefied petroleum gases
-
Equipped with excess-flow and safety relief devices
-
Used in domestic, commercial & industrial LPG cylinders
6. Medical Gas Cylinder Valves
-
Used for oxygen, nitrous oxide, medical air
-
Indexed outlets to prevent misconnections
-
Comply with medical gas safety standards
7. Cylinder Valves with Pressure Relief Devices (PRD)
-
Integrated burst disc or fusible plug
-
Protects cylinders from over-pressure
-
Common in industrial and specialty gas cylinders
8. Pin Index Cylinder Valves
-
Prevents wrong gas connection
-
Mainly used for medical gas systems
-
Meets international safety indexing standards
9. Integrated Valve with Regulator (VIPR)
-
Combines valve and pressure regulator
-
Compact and user-friendly design
-
Widely used in medical and specialty gas applications
10. Special-Purpose High-Pressure Valves
-
Designed for corrosive, toxic, or ultra-high-pressure gases
-
Stainless steel construction
-
Custom outlet connections available
