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.
• Adjustable Components Options: Offers various adjustment elements such as knobs, hex sockets with protective caps, and scaled lockable knobs for user convenience.
• High-Performance Materials: Manufactured with durable, corrosion-resistant materials and excellent sealing properties for long-term stable operation.
