PRODUCT INFORMATION

Pressure Reducing Valve IR-420-XZ

The Bermad Model IR-420-XZ Pressure Reducing Valve is a hydraulically operated, diaphragm actuated control valve. This valve reduces higher upstream pressure to lower constant downstream pressure—regardless of fluctuating demand—and opens fully upon line pressure drop.

APPLICATIONS

  • Pressure Reducing Stations
  • Flow and Leakage Reduction
  • Systems Subject to Varying Supply Pressure
  • Energy Saving Irrigation Systems
  • Downhill Supply Lines
  • Pressure Zoning
  • System Maintenance Savings

TECHNICAL DATA

OPERATION

The Pressure Reducing Pilot senses Downstream Pressure. It diverts line pressure into the Control Chamber should rise above setting. Pressure then accumulates in the control chamber causing the Valve to throttle closed, decreasing to pilot setting. The pilot releases accumulated pressure to the atmosphere when falls below setting, thereby causing the Valve to open. Should line pressure remain below setting - the Valve opens fully. The Manual Selector enables local manual closing.
