1356 Differential Pressure Pilot

The Model 1356 is a two-way, normally closed pilot, that senses high pressure under its diaphragm, low pressure above the diaphragm, and balances the differential pressure against an adjustable spring load. An increase in differential above the spring set point tends to make the pilot open.

The Model 1356 is the standard pilot for OCV Series 110 Differential Control Valve. Sensing high and low pressures and opening at the differential set point, the pilot modulates the main valve to maintain the required differential pressure.

  • Normally Closed, increasing differential pressure opens
  • Multiple spring ranges for accurate control
  • Can be local or remote sensed
  • Simple adjustment
  • All parts replaceable while mounted on valve
  • Rubber to metal seat for positive shut-off
  • Bronze or stainless steel construction
