Flow regulators DV and flow regulators with reverse flow control DRV HYDAC are, in accordance with DIN-ISO 1219, valves designed to control the flow in hydraulic systems by means of an adjustable constriction of the cross section.

The flow rate depends on the difference in pressure and viscosity. DV Flow Control Valves feature a specially designed throttle mechanism to allow for precise flow regulation and shut-off. Flow control and shutdown work in both directions.

HYDAC flow control valves with reverse flow control DRV allow for the same precise regulation of flow rate. The flow control and shut-off function, however, only work in one direction. Unrestricted Flow in the reverse direction is via the built-in valve.

Additional advantages of these valves are:

• Space-saving in-line mounting thanks to the compact design
• A high level of safety obtained with a patented safety mechanism
• Screw locking setting
• the choice of nine sizes ensures the best possible fit to the system.
• Mounting location is optional.
• For size 20 and above, the valve can be set with a wrench.
