Hydraulic Adjustable Pressure Reducing Valve in Piston Type with
Strainer
PRODUCT INTRODUCTION
1. Description
Hydraulic Adjustable Pressure Reducing Valve in Piston Type with
Strainer is automatic hydraulically-operated moving the main disc upwards or
downwards so as to close and open the valve. By this way, it
adjusts downstream pressure at the preset value by the pilot. When
downstream pressure is higher than the preset value, PRV
automatically closes. It can produce constant outlet pressure not
matter how the inlet pressure changes. It can maintain the preset
pressure value regardless fluctuating downstream flow. The adjust ratio set by the pilot is big, outlet
pressure can be reduced by 10-80% of the inlet pressure.
2. Cost & Space saving
This multifunctional series valves are with a builtin strainer
which is much more cost saving and space saving than one normal
multifunctional hydraulic control valve and one strainer device.
This valve is popularly used in Daily water supply system, Fire
protection system and Industrial water supply system.
