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 CRQ valve is a pilot operated pressure control valve cartridge type that can be used in blocks or panels with D-10C type seat.
It is normally used to control the hydraulic circuit pressure and allows use of the entire flow of the pump even at pressure values near the set value.
It is available in four different pressure control ranges up to 350 bar.
It consists of a main balanced type spool and a pilot stage. The main spool, normally closed, opens when the circuit pressure exceeds the set value generated by the pilot stage, discharging the excess flow in port T, directly connected to the tank.
The pressure is adjustable with a screw, usually supplied as the countersunk hex type, equipped with locking nut and with maximum adjustment limiter.
