Gas valves allow gases to be filled into or emptied from a cylinder.
Its function is critical as the compressed gases within them are subject to explosion if mishandling is caused.
It is the most vulnerable part of a compressed gas package.

Cylinder Valves Types

There are typically four types: the O Ring valve, the diaphragm valve, the entire valve, and the pressure seal valve.

Diaphragm Seal Valves

Diaphragm Seal Valves
Handwheel operated, two-piece spindle, soft seated

Common valve body materials
Stainless steel, Brass

Gas Valve Description

These valves use diaphragms for gland sealing which gives the valves superior leak integrity.
The gland nut threads into the valve body & clamps the outer edges of the diaphragms against a ledge in the valve body to form a seal.
The lower spindle assembly is non-threaded & non-lubricated, encased in a spring that forces it away from the seat when the valve is opened.
The upper spindle is threaded into the gland nut. The valve opening is restricted by the stroke of the diaphragm, limiting the flow through the valve.

Cylinder Valve Application

The design is highly suitable for toxic, pyrophoric & high-purity gas. Due to the high torque required to close the valve by overcoming cylinder pressure X area of the diaphragm plus the spring force, these valves are limited to cylinder pressure up to 200 bar.

DSW shelf cylinder valves for all segments of the compressed gas market include medical, oxygen, propylene,
industrial gases, alternative energy, and more. DSW test the valves at full working pressure before dispatching them to consumers.
