Features and Benefits

• Closed bonnet for spring protection.
• Pilot gag prevents the pilot-operated relief valve from opening while equipment is undergoing operational hydrostatic testing.
• Pop action and modulating pilot allows for application versatility.
• Unique pilot seat design allows for self cleaning operation and is tolerant to icing and dirty conditions.
• Adjustable blowdown - the first and only non-flowing modulating pilot with main valve blowdown control.
• Remote actuation and sensing.
• Operation closer to set point improves process efficiency versus direct spring operated valves.
• The metal seat option incorporates proven technology from the 1900 series safety relief valve seat design.
• The addition of a heat exchanger increases the metal seat option temperature range to -320°F (-196°C) to 650°F (343°C).
