NUMATICS VL52 & VT52 Lockout Valves

Numatics lockout valves prevent unauthorized pressurization of an air system during service or maintenance. Numatics lockout valves employ 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 lockout valve cannot be operated until the padlock is removed.

 

Numatics lockout valves are available in several different designs including Manual, Slo-Start and Modular. Each lockout valve is equipped with an emergency shut off feature that quickly exhausts downstream pressure to atmosphere.

 

The optional Slo-Start Valve feature gives an operator the ability to turn the spool’s red knob in the CCW direction gradually increasing downstream pressure, before opening to full flow conditions.
