1000 Series Pressure Sustaining and Relief Valves
Features

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 reducing, and rate-of-flow.
  • Works well as a "quick relief (QR)" valve at sand media stations, opening faster and relieving more flow than competitive options.
