The type 2900 pilot-operated safety relief valve combines the advantages of two products into one— the 1900 safety relief valve and the 3900 POSRV. The 2900 POSRV can replace spring-loaded relief valves without requiring modified outlet piping. Specifications : • Inlet Sizes: 1″ through 12″ • Outlet Sizes: 2″ through 16″ • Orifice Sizes: D through W • Set Pressure Range: 15 to 6250 psig • Temperature Range: -40°F to 505°F • Materials: Stainless steel pilot with carbon steel main valve and SS trim • Certification: ASME Section VIII, PED and SQL Download Data Sheet

The type 3900 pilot-operated safety relief valve is a non-flowing design available in a modulating or pop-action pilot.The 3900 POSRV is suitable for the overpressure protection of many pressurized systems and vessels in the chemical, petrochemical, paper mill, oil and gas production and transmission Specifications : • Inlet Sizes: 1″ through 10″ • Outlet Sizes: 2″ through 10″ • Orifice Sizes: Fourteen sizes- D throughT • Set Pressure Range: 15 to 6250 psig • T emperature Range: -40°F to 505°F • Materials: Stainless steel pilot with carbon steel main valve and SS Trim • Certification: ASME Section VIII,PED and SQL Download Data Sheet

The highly adaptable type 1900 safety relief valve meets numerous application requirements.The type 1900-UM valve is capable of flowing liquid, gas or steam with no adjustment required to switch between different media with the same set pressure. Specifications : • Inlet Sizes: 1″ through 12″ • Inlet Ratings: ANSI Class 150 through 2500 • Outlet Sizes: 2″ through 16″ • Outlet Ratings: ANSI Class 150 and 300 • Orifice Sizes: D through W • Set Pressure Range: 4 psig to 6250 psig • Temperature Range: -450°F to 1500°F • Materials: Cast carbon steel body with stainless steel trim • Certification: ASME Section III and VIII, PED and SQL Download Data Sheet

The type 19000 valve is ASME and PED certified. It meets and exceeds API seat tightness performance. The 19000 offers enhanced capacity and blowdown performance on many media types. In most cases, it does not require parts changes to accommodate different media. Specifications : • Inlet Sizes: 1/2″ to 2″ • Outlet Sizes: 1″ through 2 1/2″ • Orifice Sizes: .019″ through .567″ • Set Pressure Range: 5 psig to 15000 psig • Temperature Range: -425°F to 1100°F • Certification: ASME Section III and VIII,PED and SQL Download Data Sheet
