Bleed gas diaphragm valves feature: automatic pilot valve, bleed gas operator, inlet and outlet screens, manual gas cock valve, pilot adjusting key, pilot gas filter and pressure regulator.
Regulated models offer the additional feature of straight line pressure regulation, allowing application of the 700 diaphragm gas valves to a wide range of capacity requirements without regulator readjustment. Minimum application for regulated models is 10% of capacity shown.
These valves are most commonly used on commercial water heating equipment in conjunction with the 1352 (CWH-3) bleed gas temperature controllers.
