Brief introduction:
Product features:
Screw-in cartridge;
Small size; compact structure;
Direct-operated, poppet-type;
Optional pressure adjustment spring.
Function:
When the pressure value of port P is 85% of the spring set pressure, oil port P to T will be closed; If the pressure is more than 85% and continue rising, the fluid will be relieved from port P to T, till to the max spring set pressure value. (note: the rate 85% is an approximate value, it’s normal that the actual value may slightly deviates.)
