To Accuseal, Value means:• Reliable Product Performance

• Responsive Customer Support

• Competitive Pricing

• On-time Deliveries

The Series ASV10 & ASV20 safety relief valves provide an economical solution for your pressure reliefapplications. 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 ensurebubble-tight seating. Pressure acting on the seat area overcomes the spring pre-load and opens thevalve at the set pressure.

The spring, assisted by dome pressure, reliably closes the valve once the system pressure drops belowthe reseat pressure.

ASV10’s and ASV20’s open with minimal overpressure to assure protection of your personnel, yoursystems, 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 NationalBoard of Boiler and Pressure Vessel Inspectors, Columbus, Ohio.

Accuseal safety relief valvesmeet the requirement of theNational Board.

SERIES ASV10/20 ACCESSORIES

INLET PORTA 1/4” NPT inlet port can be provided on theInlet sub to install instrumentation like apressure gage, or apply pressure below theseat to test the valve, in combination with afull-bore block valve upstream.

SPECIAL CONNECTIONSAND MATERIALS

Array offers special inlet and outlet connections, other than as shown on page 4,to your exact specifications, as well as specialty alloys and elastomers to meetyour special service conditions.

SPRING CARTRIDGESSpring Cartridges, which include the Spring and therequired Spring Bearings, are provided to change setpressures. Springs meet Code requirements.

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

For details, discuss the above options further with an Array sales specialist at 1-281-977-8500.

LIFT LEVER ASSEMBLY

A lift lever assembly is available for all sizes to test theoperation of the valve assembly. By turning the outerhandle, the inner rod is lifted which in turn picks upthe 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, orwater above 140o F. For all other applications, thisfeature is optional.
