7-way Valves-7L Flow Path

This type of valve can connect one side port to the bottom port, and shut off other 5 side ports at the same time. Switching can be done in 60° increments with 360° rotation handle.

Crossover (4- 6-Way) Valves

4-way Valves-4C Flow Path

This type of valve can connect two groups of adjacent ports at the same time. Switch between 0° and 90°positions with 90° rotation handle.

6-way Valves-6C Flow Path

This type of valve can connect three groups of adjacent ports at the same time. Switch between 0° and 60° positions with 60°rotation handle.

Special Flow Path

3-way Valves-3HL Flow Path

This type of valve can connect one side port to the bottom port, or connect two side ports to the bottom port. Switching can be done in 90° increments with 180° rotation handle.

4-way Valves-4H Flow Path

This type of valve can connect two opposite ports. Switch between 0° and 90° positions with 90° rotation handle.

4-way Valves-4HL Flow Path

This type of valve can connect three adjacent ports and shut off other ports. Switching can be done in 90° increments with 360° rotation handle.

4-way Valves-4V Flow Path

This type of valve can connect two adjacent ports and shut off other ports. Switching can be done in 90° increments with 360° rotation handle.

5-way Valves-5HL Flow Path

This type of valve can connect three side ports to the bottom port, and shut off the fourth side port at the same time. Switching can be done in 90° increments with 360° rotation handle.

5-way Valves-5H Flow Path

This type of valve can connect the bottom port to port 2 and port 4, or connect the bottom port to port 3 and port 5. Switch between 0° and 90° positions with 90° rotation handle.

5-way Valves-5LV Flow Path

This type of valve can connect two adjacent ports to the bottom port, and shut off other two side ports at the same time. Switching can be done in 90° increments with 360° rotation handle.

Vent Port Options

Vented Valves
The maximum working pressure for vented valves is 500 psig (34.5 bar).
Straight-pattern Valves
A vent hole in the side of the valve body makes the downstream port vent to atmosphere when the valve is closed.
Angle-pattern and 3-way Valves
A vent hole in the side of the valve body makes the bottom port vent to atmosphere when the valve is closed.
Welded Vent Port Connections
A OJFLUID tube fitting or a tube stub welded to the vent port is available for stainless steel vented valves.
