Numatics™ VL Lockout Valve
The ASCO Numatics Series VL is a standard manual lockout valve that prevents unauthorized pressurization of an air system during service or maintenance.
The valve employs a unique, one-piece center spool design that accommodates a user-supplied padlock in the closed position. When locked in the closed position, the pneumatic system controlled by the valve cannot be operated until the padlock is removed.
