Symbol for 2 port valve with two positions, one position valve open with flow in … A compressor bypass valve (CBV), also known as a pressure relief valve or diverter valve, is a manifold vacuum-actuated valve designed to release pressure in the intake system of a turbocharged vehicle when the throttle is lifted or closed.This air pressure is re-circulated back into the non-pressurized end of the intake (before the turbo) but after the mass airflow sensor. If a pressure relief valve is used conjunction with a pulsation damper DBG, the pressure relief valve must be installed upstream the pulsation damper. Some dampers can be used for pressure relief and some are used within particular HVAC systems. Non-powered flue damper- Increases efficiency as it automatically opens and closes to reduce heat loss in the standby mode; Electronic gas control-Intelligent control logic provides enhanced operating parameters and tighter differentials for precise sensing and faster heating response to optimize performance These vanes offer better strength with less noise and static pressure; Counterbalanced backdraft damper – like backdraft dampers, they are also made of galvanized steel and designed to fulfill application needs depending on pressure, temperature, and velocity. Your Message. Reliable. The set pressure of a relief device is the pressure at which the device operates. Adjustable pressure controller is available for field setting of relief pressure. They are used to regulate the airflow through the ventilation system from an input control signal, typically 4 to 20 mA or 0 to 10V.
