This DEVaaM make Pilot operated safety relief valves operated bubble tight at higher pressure to set pressure ratios. Allowing operators to run very close to the systems allowable maximum pressure, while protecting the system from over pressure. This valve allows maximum product output, increase profitability & reduces fugitive emissions. When valve is inline & operational, Inline services, settings & blow down adjustments are quick & easy. These valves are designed as per Section VIII of ASME boiler & are mainly used in ASME make Boilers, Pressure vessels, for Air, Gas, Vapor & liquids.

Auto Re-circulation on a Refueller to control the pumping pressure of Air Crafts. Solenoid Override or Pneumatic Override to safeguard the system. This can be operated remotely to re-circulate full flow. When installed in Main line, it prevents upstream pressure dropping below preset value. When installed on a By-Pass line, it controls main line pressure by relieving excess pressure in By-Pass/sump. Ideal for pump by pass to protect the downstream equipments. Relief pilot (F22) is normally closed due to spring tension. With increase in upstream pressure above set value, Pilot (F-22) opens which makes Main Valve to open fully.
Models: – DA 422 (Globe), DA 4220 (Angle).
Size: – 25 NB – 750 NB.
Spring Range: – Standard: 20-175 Psig, Optional: 5-35 Psig.
Materials: – Carbon Steel, Alloy Steel, Stainless Steel etc.
