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