Product Overview

Type DR 10 DP is a pressure reducing valve which is used to control the pressure. The fact that Huade® pressure valves can replace the same series products offered by Rexroth is mainly due to the long-term cooperation with Rexroth. Compared with other similar brands, Huade® products are more advanced in technology and more durable. The prices of these pressure reducing valves are relatively cheap. The factory is a national key enterprise and has a high reputation in China .

Industrial Applications

  • Pressure reducing valve type DR 6 DP is used to reduce the system pressure.
  • The valve type DR 10 DP is a direct operated valve of 3 way design, with a pressure relief function on the reduced pressure side.
  • Pressure setting is by means of the pressure setting element (1).
  • At rest, the valve is normally open, and fluid can flow unhindered from port B to port A. Pressure in port A is also present on the end of the spool (2), via control line(4), opposing the compression spring (3). When the pressure in port A reaches the pressure level set at spring (3), spool (2) moves to the control position and holds the pressure in port A constant.  
  • Fluid to control the valve is taken from port A via control drilling.
  • If the pressure in port A rises still further due external forces, the spool (2) is moved still further towards the compression spring (3).
  • This causes a flow path to be opened over control land(5) in the control spool(2) to tank (port Y) . Sufficient fluid then flows to tank to prevent any further rise in pressure.
  • The spring chamber (6) is drained to tank externally via port Y.
  • An optional non return valve (7) is available to allow free flow from port A to port B.
  • A pressure gauge connection(8), permits the secondary pressure to be monitored.
