HYDAC offers a wide range of direct acting and pilot operated Relief and Reducing Valves. In general, the direct acting valves are faster in response while pilot operated valves have flatter pressure/flow characteristics.

HYDAC Pressure Reducing Valves are direct acting and pilot operated spool types with optional pressure adjustment ranges up to 5000 psi (350 bar). They have been designed to maintain a constant secondary regulated pressure regardless of pressure variation in the primary system

Operation

N/A The DB06C blocks flow from 1 to 2 until the predetermined pressure setting is reached at port 1 to lift the spring opposed poppet from its seat, allowing flow from port 1 to port 2. Pressure at port 2 is directly additive to valve pressure setting. Flow from port 2 to port 1 is checked.
