Stacked Pressure Reducing Valve MRP-03 MRA-03 MRB-03 Hydraulic Reducing Valves

Stacked Pressure Reducing Valve MRP-03 MRA-03 MRB-03 Reducing Valves 03 Series

Features

The modular valves are functional elements with which a hydraulic system can be composed and built easily by stacking them with the mounting bolts. Therefore, no piping is required for the manufacture of the hydraulic systems. Seric's 03 Series Modular Valves are widely used to compose the hydraulic systems for the various industrial equipment including machine tools, special purpose machines and injection moulding machines. The valves have standardized mounting surface conforming to ISO 4401-AC-05-4-A and optimum thickness for the stacking.

Specifications

★In pressure adjustment range "H", if the pressure in the primary side is set above 20 MPa (2900 PSI) and the pressure in the secondary side is set below 10 MPa (1450 PSI), the maximum flow is limited to 50 L/min (13.2 U.S.GPM).

Instructions

●The minimum adjustment pressure equals the lower limit of either pressure adjustment range (B, H) plus the tank line back pressure of the next page. This back pressure should include the value of the T-line pressure drop characteristics of the values stacked to the base plate side of the modular valve.

●To make pressure adjustment, loosen the lock nut and turn the pressure adjustment screw clockwise or anticlockwise. For an increase of pressure, turn the screw clockwise. Be sure to re-tighten the lock nut firmly after making adjustment to the pressure.
