Air-operated 2-port valve Cylinder Valve SAB*W Series

Brand :

CKD

Caution

Product Description

This is an air-operated valve with a cylinder drive system, available in a wide range of connection port diameters from Rc1/4 to 50 flange. Compatible with water, air, steam, and low vacuum; a solenoid valve-equipped model is also available.
[Features]
· Cylinder drive system using external pilot air provides strong resistance to contaminants and ensures reliable opening and closing.
· A lineup of series compatible with water, air, low vacuum, and steam. By selecting body and seal materials as options for each series, an even wider range of fluids can be accommodated.
· The actuator section can be oriented in four directions, making piping and wiring work easy.
[Applications]
· Ideal for controlling water and non-corrosive fluids.
