Netherlocks’ manifold interlocks ensure that instrumentation valve operation on hydraulic manifolds conforms to process protocol. The interlocks are ideal for use on manifolds with 1oo2 (1-out-of-2), 2oo3 and 3oo4 configurations. Netherlocks’ manifold interlocks are constructed from corrosion resistant 316 stainless steel. They use small operating keys to control the locked open (LO) and locked closed (LC) positions of the instrumentation valve. When installed, an operator can no longer deviate from the process procedure. Netherlocks’ manifold interlocks can be customized to fit any type of manifold manufacturer, including Parker, Swagelok and Aptek.
