The Series 300 & 400 consists of the particular range of pressure reducing valve. The valve's name itself narrates function. The valve automatically reduces a higher inlet pressure to a steady outlet pressure to a steady lower downstream pressure regardless of changing flow parameter and fluctuations in upstream. A solenoid valve is provided to intercept the operation of the pressure reducing control. Specifications Pressure Class : 150 & 300 # Temperature Range : -40 to 90 deg.C.
