monoblock valve


According to the amount of control, directional control valves can be divided into single-control type and dual-control type. Single control type means that when the control signal disappears, one working position of the valve is obtained by the control signal, and the other working position is obtained by other forces (called reset mode). For example, the return of a spring force is called a spring return; Air pressure reset is called air pressure reset; The return of spring force and air pressure is called a hybrid return. Hybrid reset reduces the diameter of the spool reset piston. The greater the reset force, the more reliable the valve reversing and the more stable the work. Dual control means that the valve has two control signals, and the two-position valve adopts dual control. When one control signal disappears and the other control signal is not added, the original valve position can remain unchanged, and the valve has a memory function. For three-position valves, each control signal controls one valve position. When neither control signal is present, the spool is in the neutral position by spring force and/or air pressure. 

There are many types of directional control valves on the market, and at the same time they are of varying quality. If you buy a directional control valve produced by an unreliable company, you may face a series of problems such as poor product quality, high price, and insufficient after-sales service. If you haven't found a trustworthy company yet, then choose us Hanjiu Technology Co., Ltd.
