Marchesini VPR3 3/8" BSP 3 Port Flow Control

This pressure-compensated flow control valve maintains a constant flow to port P, ensuring precise flow regulation regardless of pressure fluctuations or inlet flow variations. Any excess flow is diverted to port B, making it available for secondary functions. While port B remains unaffected by pressure changes, it is sensitive to flow variations.

Designed for durability and reliability, the valve features a zinc-plated steel body, hardened and ground internal components, and BUNA N standard seals. Its matched diameter design ensures minimal leakage and efficient load holding.

For proper installation, connect port E to the supply, port P to the actuator or a hydraulic circuit requiring controlled flow, and port B to the tank or a second actuator. Flow settings can be adjusted by rotating the hand knob after loosening the locking nut.

Engineered for stability, precision, and efficiency, this valve is an essential component for hydraulic systems requiring consistent flow control and multi-function capability
