Check Valves for Control Systems
 These check valves seal bubble tight even without back pressure and provide a smooth, minimum resistance flow path when open. The poppet is spring loaded for operation in any position. The spring load is borne by a metal stop, rather than by the soft seat, ensuring long seal life and minimum maintenance. Operation is smooth and chatter-free.
