Duplomatic Oleodinamica represents the real alternative in the hydraulics market.

Duplomatic’s wide range of products and worldwide service network, grant its users a real competitive advantage.

The Duplomatic 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.
