PC-04 Hydraulic Operated Check Valves (Poppet-type)

SPECIFICATIONS:
Max working Pressure:       250bar

WORKING POSITION:
Pressure at ② overcomes the spring-bias poppet and allows free flow to ③. Flow in the opposite direction, from ③ to ②, is blocked by the poppet. When the required pilot pressure is achieved at ①, the poppet unseats and allows flow between ③ and ②. The pilot piston area to poppet seat area ratio is 2.8 to 1.
