Accuseal Relief Valves

The Series ASV10 & ASV20 safety relief valves provide an economical solution for your pressure relief applications. They are ideal for a variety of gas/vapor and liquid services, including pipelines, separators, compressors, coolant circulation systems, as well as many unique OEM applications.

These are direct spring operated valves with a fixed blowdown. They utilize a soft seat to ensure bubble-tight seating. Pressure acting on the seat area overcomes the spring pre-load and opens the valve at the set pressure.

The spring, assisted by dome pressure, reliably closes the valve once the system pressure drops below the reseat pressure. ASV10’s and ASV20’s open with minimal overpressure to assure protection of your personnel, your systems, and your investment.

Accuseal offers value through reliable performance of products in service as well as from qualified, professional personnel supporting the product before and after delivery.

ACCUSEAL products meet the requirements of the ASME Boiler and Pressure Vessel Code Sec. VIII, Div. 1 for Air, Gas, and Liquid. Capacity ratings were established by testing performed at the National Board of Boiler and Pressure Vessel Inspectors, Columbus, Ohio.
