Pressure Reducing/ Relieving Valves MV9-5

General Description

These two-stage spool valves maintain reduced outlet pressure against variation in inlet pressure above selected valve settings. These valves are able to act as relief valves (at 50% of maximum flow) to prevent excess pressure being developed when an actuator is subject to a reactive load. Relief flow is directed to the "Tb" port . Therefore, for the relief function to operate, all components above this MV-9 module must contain the "Tb" port and the Directional Valve must have the "Tb" bypass feature. Pilot control may be from the "P", "A" or "B" port. Pilot drain flow may be directed internally to tank port "Ta" or externally out of the valve body. The valve pressure setting is adjustable by means of either an adjusting screw containing an internal hex. Different spring ratings cover an overall pressure range from 2 to 315 bar (30-4500 psi).
