Pressure Reducing Valve DR 10 DP

Huafilter specializes in providing Huade® pressure reducing valve DR 10 DP. We are the authorized distributor of Huade Hydraulic, aiming to provide customers with high-quality products. Huade® hydraulic valves are widely sold at home and abroad because of its high quality and low price. It is worth considering as an affordable alternative option to first-line brand. We guarantee the quality of the pressure reducing valves for one year. We also have professional technicians who can provide technical support. Choose cost-effective hydraulic products, choose us!

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 .

Section and symbol of Pressure Reducing Valve DR 6 DP

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.
