Sigma Valves as a company was founded in 1968 to provide a solution to the requirement for a non-automatic reset relay valves in stainless steel. Today Sigma has a wide variety of master relay valves for safety system automation. From basic actuator control circuits to complicated multi-well control systems with low pressure pneumatic and hydraulic circuits, Sigma has a valve for every application. The original 11RRS Series has the ability to initiate shutdown on low supply pressure conditions. This keeps an actuator or a system from operating at marginal ranges where actuated instruments may be partially closed or not functioning. There are additional models to meet whatever requirement one may have for manual relay type valves.
