9100 Threaded Series is state of the art when it comes to a soft seat and high flow rate design. It is an industry leader in pressure relief devices with a reputation for safety and reliability, low maintenance, and cost effectiveness. Our soft seat and fully guided disk design outlasts the competition and produces a valve that has consistent set pressures and a field proven tight lip seal. A tighter seal reduces leaks and limits product loss which leads to increased productivity and safety. The 9100 Threaded Series valve is manufactured in accordance with the requirements of ASME Boiler and Pressure Vessel Code, Section XIII UV stamped applications. This valve is well suited for specialty gases, compressors, separators, gathering lines and anywhere else you need a safe and reliable valve. With a service range of 10 psig to 3500 psig and a wide array of options and applications, our 9100 Threaded Series is a valve that you trust.

9100 Threaded series, our 9100 Flanged Series is also state of the art when it comes to a soft seat and high flow rate design. It is an industry leader in pressure relief devices with a reputation for safety and reliability, low maintenance, and cost effectiveness. Our soft seat and fully guided disk design outlasts the competition and produces a valve that has consistent set pressures and a field proven tight lip seal. A tighter seal reduces leaks and limits product loss which leads to increased productivity and safety. The 9100 Flanged Series valve is manufactured in accordance with the requirements of ASME Boiler and Pressure Vessel Code, Section XIII UV stamped application for Air/Gas and Liquid service. This valve is well suited for specialty gases, compressors, separators, gathering lines and anywhere else you need a safe and reliable valve. With a service range of 10 psi to 3500 psi and a wide array of options and applications, our 9100 Flanged Series is a valve that you trust.

9500 Snap Pilot Series is designed to pop open in response to pressure pickup at the inlet of the main valve. Our snap pilots have an adjustable blowdown that alters the set spring deflection once the valve has popped and the greater the deflection, the shorter the blowdown. Our 9500 Snap Pilot is based on proven control design principals, featuring our "Auto Seat Technology"®. The 9500 Snap Pilot Series valve is manufactured in accordance with the requirements of ASME Boiler and Pressure Vessel Code, Section XIII UV stamped applications for Air/Gas service. When you need to regulate system pressures and maintain overall quality, you need a safe and reliable valve. With a service range of 15 psi to 4500 psi and a wide array of options and applications, our 9500 Snap Pilot Series is a valve that you trust.

9500 Gas Modulating Series is designed to gradually open the main valve in response to system overpressure. Modulating pilots produce far less shock on a system and provide considerable resistance to wear and tear on the main valve components. Our 9500 Gas Modulating Pilot is based on proven control design principals, featuring our "Auto Seat Technology"®. The 9500 Gas Modulating Series valve is manufactured in accordance with the requirements of ASME Boiler and Pressure Vessel Code, Section XIII UV stamped applications for Air/Gas service. You need a safe and reliable valve when it comes to regulating system pressures and maintaining overall quality. With a service range of 15 psi to 4500 psi and a wide array of options and applications, our 9500 Gas Modulating Pilot Series is the valve you can trust.

9500 Liquid Modulating Series is designed to gradually open the main valve in response to system overpressure. Modulating pilots produce far less shock on a system and provide considerable resistance to wear and tear on the main valve components. Our 9500 Liquid Modulating Pilot is based on proven control design principals, featuring our "Auto Seat Technology"®. The 9500 Liquid Modulating Series valve is manufactured in accordance with the requirements of ASME Boiler and Pressure Vessel Code, Section XIII UV stamped applications for Liquid service. When you need to regulate system pressures and maintain overall quality, you need a safe and reliable valve. With a service range of 15 psi to 1480 psi and a wide array of options and applications, our 9500 Liquid Modulating Pilot Series is a valve that you trust.

The weather cap is a PVC valve cover that is the best insurance against valve deterioration caused by all external elements. When installed properly this simple design can help protect your equipment from various kinds of intrusion into your valves and piping systems. Environmental degradation such as small animals, birds, insects and other critters calls for a product that can protect your equipment.
