In order to ensure safe operation of gate valves, Alcatraz Interlocks provides multi turn locks, with both single and double keys in two sizes to fit correctly on all common gate valve sizes.
Alcatraz integral multi turn (type DML/SML) valve interlocks fit on all types of handwheel operated valves, such as gate, globe and all gear operated valves. The interlocks are easy to install, even when the valve is in a live process.
They are mounted on multi turn valves to interlock the locked open and/or locked closed position of the valve. The key movement is only possible in fully open / closed position thus providing an extra confirmation that the valve is in the exact desired position as compared to car seals etc.
Alcatraz’ Interlocks for gate valves can be used in multiple situations like control valve flow, ensuring safe valve operation, safe switchover of pressure safety valve systems and operation of pig trap systems. To offer the right interlock for a gate valve we need to understand your application and sequence of actions. To execute this properly our dedicated team could assist you with measurement, commissioning and installation. Gate valves are commonly used in applications like:
Gate valves utilize a handwheel to operate. To lock these valves we have designed two kinds of interlocks depending on your sequence (linear or nonlinear), our engineering department will design it.
