Kirk HD Type VL ball valve interlock
Engineered for industrial flow control applications, the Kirk HD Type VL ball valve interlock ensures hazards, such as air and liquid flow power, are isolated before operators or engineers work on pneumatic presses, hydraulic equipment or systems with high-pressure air. The interlock fits ball valves from 1/4 to 3 in. in diameter. Operated via a stainless steel lever, the unit is made of Type 316 stainless steel.
