The simplest directional control valve is the 2way valve. Characteristics and configurations of manual directional control valves used in hydraulic systems selecting the right valve for the job. The solenoid directional control valves of the rs type are used to control the motion of one or more consumers. Whereas discrete valves generally use a spool to achieve two, three, or more positions, discrete valves use a plunger, poppet, or ball that seals against a seat. As in digital electronics, binary valves operate either on or off. On the other hand, if the valve is handling cooling water to a reactor, the flow should be maximum in case of emergency. Directional control valves can be classified in a number of ways. A guide to selecting a manual hydraulic directional. Goto product focused delivery times are available only for the quantities and if applicable, the preferred options listed for the product. The flow from it is fed to a directional control valve of the rs type, which specifies which one of the. Detent in position 1, 2, 3 and straight through spool.
Directional control valves perform only three functions. Wet type solenoid operated directional control valve ss series wiring system. Detent in position 1, 2 and 3 marine version spring centered with straight through spool. Directional control valves are probably the most common of all hydraulic components and are used to control the starting, stopping and reversal of flow in a system. Even more basic than the discrete directionalcontrol valve is the binary valve. These three functions usually operate in combination. For example, if the valve is used to control steam or fuel flow, the valve should be shut off completely in case of air failure.
