Quarter-turn valve solenoid interlock 90L

All Ellis valve interlocks are available in single key (locking in open or closed positions) or dual key (locking in open and closed positions) variations. Ellis offers a range of valve interlocks for use with lever operated quarter turn valves including ball, butterfly and plug valves. Constructed in Stainless Steel, the interlock fits directly to valve in place of the exisiting lever and requires no modification or welding to the valve during fitting. When operating keys are removed, stainless steel dust covers seal the unit against moisture and dust ingress.
