Abstract
A valve for a pressure vessel system includes a housing including a cavity and a hollow fluid flow portion. A membrane actuator is disposed in the cavity of the housing. A piston is disposed in the cavity and in the hollow fluid flow portion of the housing. A spring is disposed in the hollow fluid flow portion of the housing. The spring biases a piston head toward a fluid flow port formed in the hollow fluid flow portion. The piston head seals the fluid flow port when the biasing of the piston head by the spring is not countered by an opposite deflection of the membrane actuator.
