Series 5100 Modulating Pilot Operated Pressure Relief Valves
Description
Specifications
Documentation
Revolutionary modulating action pilot operated relief valve designed specifically for Economizer service meeting the stringent requirements of ASME Code Section I. Certified capacities for steam and water. Proportional design opens according to relief demand, thereby eliminating chatter. Suitable for steam, water or flashing water service.
Anderson Greenwood Series 5100 was the first and is the ONLY non-flowing, modulating pilot operated pressure relief valve that is certified under ASME Section I. The Series 5100 is a unique soft seated pressure relief valve that requires no elastomer seats or seals. All plastic soft goods trim materials provide an economical way to handle high temperatures and aggressive lading fluids. This design provides an alternative to the traditional metal seated direct acting pressure relief valves used in these installations.
Features & Benefits:
Serve Economizer applications requiring pressure relief under the stringent requirements of ASME Section I and Code Case 2446. ASME Section I certified capacities for both steam and water.
Modulating pilot operated pressure relief valve ideal solution to difficult applications. Instead of opening quickly (as occurs with a spring-loaded valve or a snap-acting pilot operated valve), a modulating pilot operated valve would only open proportional to the specific overpressure need, thereby eliminating valve chatter.
Modulating, soft-seated, pilot operated valve offering premium tightness with the ability to handle relieving temperatures to 515°F [268°C] and a set pressure range of 15 to 6170 psig [1.03 to 454.4 barg].
It is the first all plastic soft seat and sealed valve that operates as a non-flowing modulating pilot. There are no pilot component changes required to handle service conditions changing to and from steam and water.
The soft seat in the Series 5100 main valve is more resistant to particulate damage than a metal seat, has a longer service life, and can be quickly replaced while the valve body remains installed in the line. Its unique design enables the main valve to be tight at pressures up to set point. After relieving and reseating, it stays bubble-tight, cycle after cycle.
