Series 5200 Modulating Pilot Operated Pressure Relief Valves

Anderson Greenwood Pressure Relief Valves, Pilot Operated Valves, Modulating, Anderson Greenwood Series 5200 Modulating Pilot Operated Pressure Relief Valves

Anderson Greenwood Crosby developed the new Series 5200 specifically to serve Economizer applications requiring pressure relief under the stringent requirements of ASME Section I. This unique and challenging application requires premium performance on a valve that must have ASME Section I certified capacities for both steam and water. A modulating pilot operated pressure relief valve is the ideal solution to this difficult application.

Features & Benefits:

  • Reduced product loss and pollution: soft seated pilot with a metal seated main valve for premium tightness before and after relief cycles.
  • All plastic pilot soft goods: there are no elastomer seats or seals providing for chemical compatibility with corrosion inhibitors which may be found in feedwater service.
  • Increased system output: because of total valve tightness to at least 96 percent of set pressure, the system can be operated closer to set pressure without valve leakage. The result is greater system production capability.
  • Balanced design: proper valve operation and lift are unaffected by back pressure. The Series 5200 pilot is exhausted to the outlet of the main valve with no effect on its set pressure.
  • ASME Section I Stamp: certified National Board capacities for steam and water per Code Case 2446 assures the user of independent third party flow rate verification.
  • ASME Section VIII Stamp: certified National Board capacities for steam also available.
  • Reduced noise: modulating action minimizes flow and resultant noise during normal system upset reducing noise abatement costs.
  • Non-flowing pilot: minimizes entrance of dirt and debris in the pilot. Due to low velocities within the pilot and supply tubing, most particles will drop out upstream of the pilot inlet screen.
  • Ease of adjustment: single adjustment for set pressure allows for accurate and dependable testing.
  • Rugged pilot mounting: rigid, low profile bracket mounting protects against vibration and careless handling.
