Abstract
A pneumatically actuated valve includes a valve body, an inlet duct connected to the valve body and an outlet duct connected to the same valve body, a shut-off valve acting to selectively interrupt or allow the connection between the inlet duct and the outlet duct, a control chamber associated with the valve body and includes a first deformable membrane and a second deformable membrane which are adapted to form a flexible wall delimiting a closed, sealed space inside the control chamber and which operate on the shut-off valve. The valve further includes a spacing element interposed between the first deformable membrane and the second deformable membrane to define an intermediate chamber between the first deformable membrane and the second deformable membrane, the intermediate chamber being without fluid sealing.
