Description

Invention field

[0001] The present invention relates to a two-way valve having a first opening and a second opening for introducing and discharging pressurized fluid in two directions. Background of the invention

[0002] Usually two-way valves have been used in fluid lines. The two-way valve has a first opening and a second opening for introducing and discharging pressurized fluid, and has a valve body that opens and closes a communication passage between the first opening and the second opening. The valve body is operated by the control pressure supplied through the control port.

[0003] In the traditional two-way valve, the control port is fixed at the predetermined position of the valve body. If the installation space is small, it is difficult to connect the pipe to the control port during the pipe connection operation. Because the direction of the pipe is limited, it is difficult to connect the pipe to the control port. It is difficult to freely change the direction of the ...
