GG interlocks for wheel operated valves

GG interlocks for wheel operated valves

Ellis provides a range of devices for interlocking multi-turn valves. Units are available for gate, globe and diaphragm valves, whether handwheel or gearbox operated. Constructed of stainless steel, the units replace the existing valve handwheel without further modification. Single key interlocks release a key in either fully open or fully closed positions, whilst dual key units can lock valves in both positions. Units are easily adjustable in situ to allow for valve seat wear.
