Singer Valve's pneumatic dynamic lifterSinger Valve has added an anticipating surge relief function to its pneumatic dynamic lifter, a valve used in the sewage, dirty and raw water industry. The valve features:

  • A relief pilot that opens if the pressure rises above the set point and closes drip tight when pressure falls below the set point.
  • Two three-way solenoid valves that put air into the cylinder under the piston, driving the valve open on power failure.
  • Piston and closing speed controls that operate separately from the sewage, in a clean, non-contaminating environment.
  • Easy access to flush out unwanted build-ups.
  • Heat fused heavy epoxy coating inside and out of the main valve.
  • 316 stainless steel seat and stem.
