This is a pilot-operated, spool-type, dual pressure setting relief valve. The one-stage setting is for low-pressure relief function (when there is no pilot at port 3), and the valve setting is determined by screw adjustment (customers can ask Winner to predetermine the setting at the factory). The two-stage setting for high-pressure relief function is the maximum spring setting and is non-adjustable; please inform Winner of the predetermined pressure. The pressure at port 3 must exceed 11 bar (Y=A) to move the pilot piston and compress the spring to reach the valve setting.
-
The maximum leakage is approximately 30 cc/min at 70 bar (1000 psi).
-
Working parts are heat-treated and high-precision ground to increase hardness for long life.
-
A variety of seal kit materials for different applications, see seals information under Technical Reference.
-
