Pressure Reducing Valve DR 10

Huafilter aims to provide cost-effective pressure reducing valve DR 10 for customers. We have become the authorized distributor of Huade Hydraulic from 2023. Our hydraulic valves have unique selling points. They have always come up to the international standards. Thanks to two long-term cooperation with Rexroth, Huade® pressure reducing valves are more advanced in technology and more durable in this field. The price is relative cheaper.

Pilot Pressure reducing valve DR 10 DP is used to control the pressure of the hydraulic system. The price is more reasonable compared to other international famous brand. Huade Hydraulic pays more attention to the practicality of its products. Huade Hydraulic is a national key enterprise. It has been cooperating with Rexroth twice for a long time, introducing advanced technology from Rexroth and advanced production equipment from all over the world to ensure the high quality of its pressure reducing valves. After years of development, Huade has become a leading brand in China's hydraulic industry. Huade® is a well-known trademark in China.

The main function of pressure reducing valve DR 10 is to reducing the pressure in the system.

Section and symbol of Pressure Reducing Valve DR 10

Pressure valves type DR 10 are pilot operated pressure reducing valves, which are controlled from the secondary circuit. They basically consist of main valve (1) with main spool insert(3) and pilot valve (2) with pressure adjustment element.

At rest, the valves are open, fluid can freely pass from port B to port A via the main spool insert (3).

Pressure present in port A acts upon the bottom side of the main spool. At the same time there is pressure acting on the ball(6) in the pilot valve (2) via the orifice (4) on the spring loaded side of the main piston (3) and via the port(5). Same it is acting on the ball (6) via the orifice (7), control line (8), check valve(9) and orifice (10). According to setting of spring(11), pressure builds up in front of the ball (6), in port (5) and in spring chamber(12), holding the control piston (13) in the

open position. Fluid can freely flow from port B to port A via main spool insert (3), until the pressure in port A exceeds the value set at spring (11) and opens the ball (6).The control

piston (13) moves to closing position.

The desired reduced pressure is achieved, when a balance between the pressure in port A and the pressure set at spring (11) is reached. Pilot oil drain from spring chamber(14) to tank takes place externally via control line (15).

Free return flow from port A to B can be achieved by installing an optional check valve (16).

A pressure gauge connection (17) allows the reduced pressure in port A to be monitored.
