Features and Benefits
•t

Closed bonnet for spring protection.

•t

Pilot gag prevents the pilot-operated relief valve from opening while
equipment is undergoing operational hydrostatic testing.

•t

Pop action and modulating pilot allows for application versatility.

•t

Unique pilot seat design allows for self cleaning operation and is
tolerant to icing and dirty conditions.

•t

Adjustable blowdown - the first and only non-flowing modulating
pilot with main valve blowdown control.

•t

Remote actuation and sensing.

•t

Operation closer to set point improves process efficiency versus
direct spring operated valves.

•t

The metal seat option incorporates proven technology from the
1900 series safety relief valve seat design.

•t

The addition of the 2900 series POSRV heat exchanger increases
the metal seat option temperature range to -320°F (-196°C) to 650°F
(343°C).
