MARCHESINI Bi-Directional Flow Control Valve 3/8'' BSP (30 L/min Flow Rate) Bondioli & Pavesi (VRFB9002) - S.101632

Technical Information

MARCHESINI Bi-Directional Flow Control Valve 3/8'' BSP (30 L/min Flow Rate) USE AND OPERATION
These valves are used to control the cylinder movements and block it in both directions. In order to have the descent of a load under control and avoid the load's weight being carried away the valve will prevent any cavitation of the cylinder. Type "A" is different due to the connection positions and the pilot ratio.
MATERIALS AND FEATURES
Body: zinc plated steel.
Internal parts: hardened and ground steel.
Seals: BUNA N standard
Leakage: negligible leakage. Standard setting: 320 Bar.
Oil temperature: 50° C - Oil viscosity: 30 cSt
Valve setting must be at least 1.3 times more than load pressure in order to enable the valve to close even when undergone to maximum load pressure
CONNECTIONS
Connect V1 and V2 to the supply, Cl and C2 to the cylinder to be controlled. In-line mounted.
