Parker offers a comprehensive range of directional control valves for a wide variety of media and customer applications, available in various types and configurations.

Often used to extend and then retract a cylinder at different speeds, these valves create two actions and have two exhaust ports, which allows you to control the speed of each action by attaching a flow control valve to each exhaust port. Also known as 4-way and 5/2 valves.

2019年6月5日 · The two primary characteristics for selecting a directional-control valve are the number of fluid ports and the number of directional states, or positions, the valve can achieve. Valve ports provide a passageway for hydraulic fluid to flow to or from other components.

2023年7月19日 · Directional control valves (DCVs) come in many shapes and sizes for pneumatic and hydraulic applications. Learn to distinguish the different configurations and the meaning of external markings.

Control the direction of flow or stop flow altogether with an electronic signal. These valves are also known as cartridge valves, and they screw into your mounting block. Place three - way valves between the pressure source and a single-acting cylinder.

2023年7月24日 · Directional control valves can be thought of as fluid switches that make the desired "contacts." That is, they direct the high-energy input stream to the actuator inlet and provide a return path for the lower-energy oil.

HydraForce offers a full range of cartridge style directional control valves, including check valves, lock valves, pilot-operated valves, shuttle valves, logic elements, spool valves, manual spring-return and rotary valves, brake-release valves, and proportional valves.

Control the direction of flow or stop flow altogether with an electronic signal. These valves are also known as cartridge valves, and they screw into your mounting block. Place four-way valves between the pressure source and a double-acting cylinder.

Gain complete control of your hydraulic system's flow with Danfoss directional control valves. Tailor your design with ease by choosing from our array of manual control options – be it rotary, lever, push and pull – or opt for hydraulic pilot-operated control.

2021年5月21日 · Directional control valves provide a flow path to the cylinder actuation and also a return path to the tank. Fluid pressure is controlled to perform different functions like pressure relief, sequence valve, and counterbalance valve as discussed below.
