Shut-off valve, pneumatic, brass, G 3/4", DN 20, spring closing

As a shut-off valve the article opens and closes the line through a pneumatically driven piston with the flow of a ball valve. Material nickel-plated brass is listed for this version. The article is listed with a nominal size of DN 20 mm.

Benefits

• At DN 20 mm the piston opens the full cross section and switches faster than a rotary actuator.
• The spring closing version determines where the valve goes without pilot air.
• The control pressure of 4.2 - 8.5 bar is fed through two G 1/8" pilot ports.
• The compact body with 135 mm face-to-face length and 70 mm height allows any mounting position.
• The temperature range of -20 to +80 °C depends on the seal material.

Applications

On water and oil lines the spring closing version works with 4.2 - 8.5 bar of control pressure.
