Fluid e.g. water, supply valve for livestock, has movable membrane mounted between pressurized water supplying opening and outflow opening, and immobilizing unit immobilizing peripheral edge of membrane to interior of valve body by pinching

摘要

The valve has a valve body in which a movable membrane (5) is mounted between pressurized water supplying opening (3) and a outflow opening (4). The membrane is movable between opening position in which the opening (3) is in communication with the opening (4) and closing position in which chambers are in communication with the opening (3) and one of the chambers is in communication with the opening (4). An immobilizing unit (11) has a receiving unit and immobilizes a peripheral edge (20) of the membrane to the interior of the valve body by pinching.
