1000 Series Pressure Sustaining and Relief Valves

Pressure sustaining valves are often used to protect system pipes, for example downstream of pumps to control the system flow rate, and on a tee off the mainline to act as a relief valve.

They are also frequently installed downstream of filter stations to provide adequate backflush pressure. In this application, they are often operated with a solenoid to form a pressure-sustaining-normally-open (PSNO) valve.

The Nelson pressure control pilot is famous for precision accuracy and responsiveness.

  • Accurate 3-way control pilot reduces filtration requirements
  • Adjustment ranges: 5-60 psi / 10-120 psi
  • Can be combined with other functions, including solenoid on/off, pressure sustaining, and rate-of-flow.
