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

The shut-off valve opens and closes the line through a pneumatically driven piston with the flow of a ball valve. The article is made of nickel-plated brass. The data give thread G 3/4", nominal size DN 20 mm, face-to-face length 135 mm, height 70 mm and switching function spring opening.

Benefits

• At DN 20 mm the piston opens the full cross section and switches faster than a rotary actuator.
• The spring opening 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 opening version works with 4.2 - 8.5 bar of control pressure.
