The 3323 is a poppet-type normally open relay valve.
The spring keeps this valve in an open position and pilot pressure will close the valve,
stopping the air flowing from the source of supply to the device actuated.
Because of the 'U' cup and piston arrangement, this valve lends itself extremely
well for high pressure pilot signals (hydraulic and pneumatic).
The maximum operating pressure for the pilot chamber and piston is 700 PSI.
The maximum control pressure (pneumatic) is 200 PSI.
The valve is fully adjustable, and various springs are available,
to provide the proper operating range.
The 3300 series relay valves are all made in bronze and stainless steel
and all provide years of trouble free service, in a salt water environment. |
