Numatics Modular Lockout Valve by Numatics Air Valves

Air-Oil Systems
Manufacturer: Numatics Air Valves

Numatics lockout valves prevent unauthorized pressurization of an air system during service or maintenance. They 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 system controlled by the lockout valve cannot be operated until the padlock is removed. Each lockout valve is equipped with an emergency shutoff feature that quickly exhausts all downstream air to the atmosphere.
