ZZYP-16II Controller Operation Type Self-operated Pressure Control Valve

Features

• 
  • Various valve body materials for selection, such as cast steel, cast stainless steel, low-temperature and high-alloy steel or special materials

• 
  • Pressure setting on the controller supported, which is convenient, quick and labor-saving, and allows continuous setting in running state

• 
  • Improved control accuracy, being about twice as accurate as that of ZZY self-operated type

• 
  • Highly sensitive, being capable of sensing very small pressure changes

• 
  • Large pressure reducing ratio, for example the differential pressure ratio reaches 1600 (0.8MPa before the valve and 50mmH20 behind the valve)

• 
  • Often adopted for the nitrogen sealing system of storage tanks to adjust the pressure of nitrogen in the tank
