P3 Line Valves and Non-return Valves
P3 Line Valves and Non-return Valves
Line valves isolate sections of a medical gas pipeline during maintenance or extension work, and non-return valves prevent reverse flow between sources or branches. P3 manufactures both to a British standard of build aimed at medical gas pipelines.
What is it?
Valves are supplied with copper stubs and flat-face unions incorporating o-ring seals for gas-tight joints. The handle locks in the open or closed position to prevent unauthorised or inadvertent operation. Every unit is 100% tested for leaks to atmosphere and for isolation when closed. A version fitted with EN ISO 18082 NIST connectors is available.

Frequently asked questions
Why is the handle lockable?
To prevent unauthorised opening or closing. In medical gas pipelines any unplanned isolation affects patients, so lockability is a basic requirement.
