Pressure Safety Valve
Pressure Safety Valve, when pipeline pressure rises to set pressure, the valve opens fully and release medium in pipeline until pipeline pressure drops to a predetermined value. To differentiate it from Pressure Relief Valve, Safety Valve’s outlet is one size bigger than inlet, as a safety measures for sudden and full release.
Pressure Relief Valve
Pressure Relief Valve, when pipeline pressure increase above set pressure, the valve opens gradually proportional to pipeline pressure until pipeline pressure drops to a predetermined value. To differentiate it from Pressure Safety Valve, Relief Valve’s has the same size of both inlet and outlet.

Pressure Reducing Valve
This valve suitable for fluid, air and steam. The gate is balanced-pressure designed, which will not influence the outlet pressure caused by unstable inlet pressure. When the outlet pressure responds directly to the pressure control chamber and adjust the setting pressure, it responds quickly and adjust the pressure accurately. Design of piston and diaphragm improves the inability of sustaining pressure and leakage.
