Modular Valves Check and Throttle Valves MSA-03 MSB-03 MSW-03 03 Series
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.
