Hydraulic relief valve CR series

cartridge

— The CR valve is a direct operated pressure control valve cartridge type that can be used in blocks or panels with type D-10B seat. — It is normally used to control the maximum pressure in the hydraulic circuits or as a limiting device for pressure peaks generated during hydraulic actuator movement variation. — It is available in five different pressure control ranges up to 350 bar. — The circuit pressure acts on the shutter which is directly loaded by a spring on the opposite side. Once the set pressure is reached, the shutter opens, and discharges the excess flow in port T connected directly to the reservoir. — The pressure can be adjusted by a screw, usually supplied as the countersunk hex type, equipped with locking nut and maximum adjustment limiter.
