Netherlocks' mechanical valve interlocks are operated with two color-coded keys

Netherlocks’ mechanical valve interlocks are operated with two color-coded keys, which, through a trapped key mechanism, control the open and closed position of a valve and communicate its current state. When the green key is released, the valve is locked in the “locked-open” position. For the red key to be released, the valve must be locked in the “locked-closed” position. If a valve is left in a midway position between open and closed, both keys are trapped in the device.

Netherlocks’ valve interlocks are fully mechanical with no need for electronic wiring. They can be incorporated into new construction and are designed for retrofitting older installations. All valve interlock components are made from corrosion-resistant 316 stainless steel.
