Manual proportional directional valve MHV-32 manual proportional valve, flow rate 800L / min, pressure 430bar, suitable for construction machinery, mining, metallurgy, shipbuilding, medicine and other industries. It is a load-sensitive proportional directional valve with pressure compensation. The working pressure is 420 bar, and the single-chip flow rate reaches 380 l / min. It adopts a unified modular design as a whole, which can provide reliable system solutions for manufacturers of engineering vehicles. It is simple and reliable for users to make different combinations of valve bodies according to functional requirements. It can be either a simple load-sensitive manual multi-way valve or an electronically controlled proportional control valve with a non-saturation function that is independent of the load and pump flow.
