Product details

Product Overview

• Brand & Model: The3DR10Pis a pilot-operated three-way pressure reducing valve fromRexroth (Bosch Rexroth).

• Application Scenarios: Primarily used to reduce system pressure and limit secondary circuit pressure in various industrial hydraulic systems.

------

Product Features

1. Structural Characteristics:

• Composed of a main valve with a control spool and a pilot control valve with pressure adjustment components.

• Features asubplate mountingdesign, with port mounting surfaces conforming toISO 4401-07-07-0-05standards.

2. Functional Characteristics:

• Pressure Regulation: Precisely controls the outlet pressure of the main valve by adjusting the pilot control valve, ensuring stable system pressure reduction.

• Pressure Limiting: Automatically opens when the outlet pressure exceeds the set value, releasing excess pressure back to the tank to protect the system from overpressure damage.

• Three-Way Design: Equipped with three ports (P, A, T) for inlet, outlet, and return, enabling complex hydraulic control functions.

3. Other Features:

• Multiple Pressure Ratings Available: Options include50 bar, 100 bar, 200 bar, 315 bar, etc., based on actual requirements.
