Introduction and guidance

The stem cap is fitted to the top of the valve stem to convert the manufacturer’s stem configuration to mate with operating keys

which reduces the forces acting on the impeller

BS 5561 provides you with all the requirements

for example to select the materials in order to meet the requirement for type testing for oxygen compatibility of all cylinder valves for highly oxidizing gases as specified in ISO 10297
