Directional Control Valves

　

Directional control valves are designed to direct the flow of fluid, at the desired time, to the point in a fluid power system. Directional control valves may be operated by differences in pressure acting on opposite sides of the valving element, or they may be positioned manually, mechanically, or electrically. Often two or more methods of operating the same valve will be used in different phases of its action.

J&F manufactures and supplies a full range of directional control valves which, for visitor-friendly presentation purpose, are classified into two categories in terms of operation purpose: solenoid valves (solenoid operated) and directional control valves (otherwise operated).

In the category on directional control valves, J&F supplies quality valves to meet your application needs: hand valve, foot pedal valve, mechanical valve, check valve, flow control valve, shuttle valve, quick exhaust valve, shocking equipment and vacuum valve.

• HLP series pressure controller
• HLP series pressure control can protect compressors in refrigeration and air-condition plant, and keep them from over-low pressure or over-high suction pressure.
• HLP series pressure controls can start and stop refrigeration compressors and fans of air condensers.
• HLP series pressure controls can be used not only in fluoride refrigeration, but also in air and liquid.
• HLP series pressure controls are fitted with a single pole double throw (SPDT) changeover switch. The position of the switch is determined by the pressure control setting and the pressure at the connector.
