Mechanically Operated Directional Valves

　　These valves are chiefly used to shift the pilot circuit. Rotary Type Directional Valves and Cam Operated Type Directional Valves are available.

　　一、Specifications

　　When a back pressure of more than 3 MPa (435 PSI) is generated in the tank port, be sure to use External Drain Type.

　　二、Model Number Designation

　　When a back pressure of more than 3 MPa (435 PSI) is generated in the tank port, be sure to use External Drain Type.

　　1.When selecting the Model type, be sure to give the model number from the following Graphic Symbols.No combinations other than those in the table below are allowed.

　　2. Special seals (Viton seals) are required when phosphate ester type fluids are used. (Prefix "F-" to the model numbers when ordering.)

　　1. Changeover Torque

　　When the pressure of pressure port "P" and cylinder port "A" (or "B") is set to 7 MPa (1020 PSI), the valve changeover torque will be as right side table:

　　2. 2-Way directional valves

　　Be sure to use the External Drain Type Valve of spool type "2" and plug the tank port.
