Pressure Reducing Valve DR 5 DP

As the authorized distributor of Huade Hydraulic, we specialize in providing Huade® pressure reducing valve DR 5 DP. Huade® commodity has always come up to the international standards. Huade Hydraulic has had two experiences of cooperating with Rexroth, and its products performance and quality are comparable to those of first-tier big brands. The price is reasonable. With these unique selling points, Huade® pressure reducing valves are already popular among consumers.

Pressure reducing valve DR 5 DP is used to control the pressure in the hydraulic system. Due to introducing Rexroth technology, Huade® DR 5 DP series pressure reducing valves can replace the same type of Rexroth. Huade Hydraulic has a strict testing system to ensure the high quality of its products. The series of pressure control valves are widely used in marine hydraulic system.

Section and symbol of Pressure Reducing Valve DR 5 DP

The valve type DR5 DP is a 3-way direct operated pressure reducing valve with a pressure relief function on the secondary side.

The secondary pressure is set by the pressure adjustment element (4). At rest, the valve is normally open and the pressure fluid can flow unhindered from port P to port A. The pressure in port A is at the same time, via the control line (6), present at the spool area opposite to the compression spring(3). When the pressure in port A exceeds the pressure level set at compression spring (3), the control spool (2) moves into the control position and holds the set pressure in port A constant.

The control and pilot oil are taken from port A via control line (6).

If the pressure in port A still increases due to external forces on the actuator, the control spool(2) moves still further towards the compression spring(3).

This causes a flow path to be opened at port A via control land (8) on the control spool (2) to the tank. Sufficient pressure fluid then flows to tank to prevent any further rise in pressure.

The spring chamber is always drained to tank externally via port T(Y).

For free return flow from port A to port P an optional check valve (5) can be fitted.
