Interlocks

Interlocks

Interlocks integrate with all makes and sizes of manually operated valves without modification. With minor modification, they operate with hydraulic or electrical actuators. Interlocks are tamperproof, weatherproof, maintenance-free and require no hot work or drilling for installation. They are manufactured from grade 316L stainless steel to ISO 9001 standards. Available in single- and dual-key configurations for rising and non-rising handwheel and quarter-turn lever-operated valves. The Prosafe MT (multi-turn) series can be anchored to globe or gate valve yokes with fabricated stainless steel straps, giving considerable cost and weight savings and allowing for easy valve maintenance with obstructing access.
