Product Description

Buildin Strainer Piston Type Safety Pressure Relief Valve 
MODEL NO.: GL98002

Δ The KARFAR model GL98002 Filter Piston Safety Pressure Relief Valve can be used as pressure relief valve which relieves pressure from the pipeline when pressure is higher than the preset data by pilot. It maintains pipeline pressure safely bellow the preset value and protect pipeline and equipment from damage of high pressure and sudden wave. This valve can relieve pressure in fire-protection recycling test system of high-rise building and other water supply balancing systems. 

Δ model GL98002 can also be used as Pressure Sustaining Valve, which maintains upstream supply pressure above a preset value by the pilot. This valve is popularly used in urban low-pressure water supply systems.

Δ Cost & Space saving: This multifunctional series valves are with a built-in filter so it is much more cost saving and space saving than one normal multifunctional hydraulic control valve and one filter device.
