ACCUSEAL SAFETY VALVES OPERATION & FEATURES 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.

Array 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.

SERIES ASV10/20 ACCESSORIES

LIFT LEVER ASSEMBLY A lift lever assembly is available for all sizes to test the operation of the valve assembly. By turning the outer handle, the inner rod is lifted which in turn picks up the bottom of the spring, relieves the spring preload, and allows the inner piston to open. By ASME Code, lift levers are mandatory for applications in air, or water above 140o F. For all other applications, this feature is optional.

INLET PORT A 1/4� NPT inlet port can be provided on the Inlet sub to install instrumentation like a pressure gage, or apply pressure below the seat to test the valve, in combination with a full-bore block valve upstream.

SPECIAL CONNECTIONS AND MATERIALS

SPRING CARTRIDGES Spring Cartridges, which include the Spring and the required Spring Bearings, are provided to change set pressures. Springs meet Code requirements.

OTHER ACCESSORIES Array can also provide peripheral equipment to complete your relief valve installation, including gaskets, bolting, discharge piping, and vent caps.
