Gas Reversing Valves
A set of 270 pairs of gas valves, supplied fully machined, assembled and pressure tested with full traceability for both body and spool back to a certificated melt number.
Steps For The Gas Reversing Valves Project
Gas Reversing Valves Project Step 1
Each body has a unique cast on ID number (the same number being stamped on the spool) which gives traceabilty back to to a certified BS 1452 Gd 180 melt.
Gas Reversing Valves Project Step 2
Shell cores were used in both body and the spool to give accurate and smooth internal flow faces.
Gas Reversing Valves Project Step 3
Each Valve remained as a matched pair during machining, grinding being used on the mating faces to ensure a gas tight seal. A check of the critical dimensions was included in the certification.
Gas Reversing Valves Project Step 4
Each valve is pressure tested.
