摘要：
A pneumatically actuated valve (19) comprises a valve body (29) an inlet duct (22) connected to the valve body (29) and an outlet duct (21) connected to the same valve body (29), shut-off means (7, 20) acting to selectively interrupt or allow the connection between the inlet duct (22) and the outlet duct (21), a control chamber (27) associated with the valve body (29) and including:
- a first deformable membrane (28) and a second deformable membrane (24) which are adapted to form a flexible wall delimiting a closed, sealed space inside the control chamber (27) and which operate on the shut-off means (7, 20);
the valve (19) comprising a spacing element (D) interposed between the first deformable membrane (28) and the second deformable membrane (24) to define an intermediate chamber between the first deformable membrane (28) and the second deformable membrane (24), the intermediate chamber being without fluid sealing.
- a first deformable membrane (28) and a second deformable membrane (24) which are adapted to form a flexible wall delimiting a closed, sealed space inside the control chamber (27) and which operate on the shut-off means (7, 20);
