Temperature (max) 1,000° F (538° C)

Series 200 Pilot Operated Pressure Relief Valves

Features: The Series 200 is a no-flow, pop action POPRV design principally intended for gas applications. Suitable for severe service where dirt, hydrates and high moisture levels occur in the fluid media, the Series 200 is the industry standard for pop action POPRVs.

Specifications
Orifice Sizes D through T, Full Bore valves also available
Connections 1: x 2″ to 8″ x 10″ (8″ x 10″ x 10″ for full bore)
Inlet Flange Ratings ANSI 105, 300, 600, 900, 1500, 2500
Temperature Range -423°F to +500°F (-253° to +260°C)
Minimum Pressure 25 psig (1.72 barg)
Maximum Pressure 10,000 psig (690 brag)

Series 400 Pressure Relief Valves

Features: The Series 400 is a no-flow, modulating action POPRV design suitable for gas, liquid and two-phase applications. The Series 400 represents the very best state-of-the-art technology providing safety relief valve performance not possible from direct spring PRV’s.

Specifications
Orifice Sizes D through T, Full Bore valves also available
Connections 1″ x 2″ to 8″ x 10″ (8″ x 10″ x 10″ for full bore)
Inlet Flange Ratings ANSI 150, 300, 600, 900, 1500, 2500
Temperature Range -423°F to +500°F (-253°C to +260°C)
Minimum Pressure 15 psig (1/03 barg)
Maximum Pressure 6,000 psig (414 barg)

Type 727 High Temperature POPRV

Features: The Type727 safety valve has been specifically designed to provide a valve with premium seat tightness on high temperature gas and steam service. The 727 has all metal seating surfaces and is ASME Section VIII Code Stamped.

Specifications
Connections 1/2″, 1″, 2″ threaded (NPT) and flanged ANSI 150, 300, 600
Temperature Range -20°F to +300°F (-29°C to +149¯C)
Maximum Inlet Pressure 200 psig (14 barg)
Blanket Pressure Range 0.5″ wc to 6 psig (12.7 mm wc to 0.4 barg)

Series 90/9000 Low Pressure POPRVS

Features: Designed for cryogenic and non-cryogenic storage tanks the Anderson, Greenwood Series 90/9000 POPRVs provide extremely accurate valve setting and ultra sensitive response with set pressure as low as 4″wc (10 mbarg). The Series 9000 is also available as a pilot operated vacuum breaker for highly sensitive and air-tight vacuum service.

Specifications
Connections 2″ x 3″ to 12″ x 16″
Inlet Flange Ratings ANSI 125, 150
Temperature Range -320°F to +200°F (-296°C to +93°C)
Minimum Pressure 4″ wc (10 mbarg)

Safety Selector Valves:

Features: The Anderson, Greenwood Safety Selector Valve (SSV) is a unique device, developed to provide a safe and efficient method of switching from an active PRV to a standby PRV. The SSV has less than 3% pressure drop to the active PRV inlet, in accordance with ASME Section VIII Code and API RP520 Part II. The SSV is provided with a ‘foolproof’ locking mechanism. Tandem Safety Selector Valve systems are available which allow positive and simultaneous switching of both inlet and outlet SSV’s while maintaining overpressure protection at all times.

Specifications
Connections 1″ to 8″
Flange Ratings ANSI 150, 300, 600, 900, 1500, 2500
