Product Description

DV DRV Hydraulic Flow Control Throttle Check Valves

Rexroth DV6, DV8, DV10, DV12, DV16, DV20, DV25, DV30(DRV6, DRV8, DRV10, DRV12, DRV16, DRV20, DRV25, DRV30) Flow Control Valve functioned with throttle cross-section by changing the length or Throttle Valve to control fluid flow, Rexroth DV/DRV flow control valve has the advantage of:
1: Flow adjustment range, a pressure change in a smooth flow
2. A small amount of internal leakage, if it leaked oil port, and also a small amount of leakage
3. Adjust torque is small, quick action
How to measures to reduce congestion orifice:
1. Choose a large thin bladed hydraulic radius orifice
2. Precision filters and oil changed regularly
3. Before and after the appropriate pressure reducing orifice
4. Using a smaller potential difference of metal materials, use a good anti-oxidation stability of oil, reducing the surface roughness of the orifice.
