a2 series is a full nozzle type safety valve designed according to ASME Sec. I standard for saturated and superheated steam service on drums, super heaters outlet, reheater inlets and outlets and economizer applications.
Features and Benefits
Lighter and more compact construction:
Continuous design improvements have created smaller and lighter valves to support current industry design trends, especially space and weight saving.
. Simplified maintenance and service:
Re-engineering has reduced the number of parts, making maintenance easier and more cost effective.
. High performance springs:
Safety relief valve springs are specially designed to guarantee set point repeatability.
. Nozzle design:
The method and location of attachment to the body avoids transmission of pipe stresses to the nozzle/disc mating surface
. Two-Ring Design:
Precise blowdown control is provided by the adjustable two-ring design. Blowdown may be conveniently adjusted while the valve is installed in the system.
. Shut Tight:
a2 Series valves shut off tight. Years of application engineering have resulted in special design which is recessed for pressure and temperature equalization ensuring a flat, tight seal that is capable of containing system pressure at 94+% of the valve’s set pressure.
. Precise Popping Point:
Centering of the disc through the low friction guide ensures that RADMAN’s a2 Series Safety Valves open at set pressure precisely, even after repeated cycling.
