Product Description

WALTER F8020 model Pressure Reducing Valves automatically reduces a higher inlet pressure to a steady lower
downstream pressure,regardless of changing flow rate and/or varying inlet pressure. This valve is an accurate,
pilot-operated regulator capable of holding downstream pressure to a re-determined limit. When downstream
pressure exceeds the pressure setting of the control pilot, the main valve and pilot valve close drip-tight.
