Quick Exhaust Valve
The quick exhaust Valve is designed to rapidly bleed the control pressure from an actuator or other device .It is typically used on safety valves, control valves, or other devices that must respond quickly when the control signals are removed . It is easy to install and maintain. No special tools are needed for repair and assembly
Features

fusible valve
A fusible valve is a "block-and-vent" type, temperature-sensitive flow control device. When the valve body temperature exceeds the melting point of the fusible alloy (caused by proximity to a fire or high temperature), the internal spring releases the valve disc, thereby blocking the inlet supply pressure and venting the downstream (receiving circuit) pressure through the vent port.
Fusible valves are used to shut down safety valve actuators, isolating potential fuel sources from ignition sources.
