LFF116-32 Watts

Pressure Sustaining with Solenoid (On-Off) and Hydraulic Check

Series LFF116-32, LFF1116-32 Pressure Sustaining and Solenoid (On-Off) Control Valve with Hydraulic Check Feature is designed to permit flow when upstream pressure is above the adjustable setpoint of the control pilot, and throttle toward closed when upstream pressure falls below the adjustable setpoint. It is controlled by a normally closed control pilot designed to: 1) Open (allowing fluid out of the main valve cover chamber) when upstream pressure is above the adjustable setpoint, and, 2) Close (allowing fluid to fill the main valve cover chamber) when upstream pressure is below the adjustable setpoint. An increase in upstream pressure causes the valve to modulate toward an open position. A decrease in upstream pressure causes the valve to modulate toward a closed position.

Features

  • Body and cover are constructed of strong and durable ductile iron (ASTM A536)
  • Permits flow when upstream pressure is above the adjustable setpoint of the control pilot
  • Check feature prevents flow reversal
  • Valve acts as an Solenoid On-Off Control Valve as commanded by the solenoid pilot
