2 WAY AUXILIARY PILOTED
Angle Body Piston Valves
Bronze or 316L S.S. Bodies - ½" to 2" N.P.T. [Series 8290]

The solenoid is an electromagnetic part of a valve, comprised of a coil, coretube, core and enclosure. ASCO Redhat brand offers the worlds largest selection of 2-, 3- and 4-way solenoid valves, designed to handle the most demanding fluid control applications.
General Description
These auxiliary-piloted, 2 way angle pody pison valves featurea an extra stable shaft with oversized bearings for extended service life. They have been tested to over one million cycles.
A preloaded stem seal and FPM shaft "wiper"" allow these valves to be used in aggressive and corrosive services. The watertight actuator head is double-walled for superior strength.
Fluid passes under the valve seat to eliminate damaging water hammer. A reversed flow version for rapid cycling steam applications is also available.
The valves can handle back pressure to their full rating.
Fluids handled: Air, water, inert gas, oil, light slurries and steam
