The Tube-O-Matic™ valve uses hydraulic or pneumatic pilot pressure to open and close on an airfoil center coil. For full valve closure, pilot pressure of 10 psi over the line pressure is required. Stainless steel, PVC, and Teflon are available options to the valve's standard nickel-plated brass wetted parts. The valve is suitable for environments where machine tool coolant is used.
