NUMATICS VL42 & VT42 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 42 Series lockout valves are available with the standard manual construction (VL42 Series) and the Slo-Start construction (VT42 Series). These modular constructions can be easily mounted to the 42 Series FRL assemblies. 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.
