Diaphragm Type Control Valve
We are proposing an extensive assortment of Diaphragm Type Control Valves. They are used for controlling the flow by opening of valve with the help of air pressure that is applied through a pilot valve into the actuator which further raises the diaphragm connected to the valve. They are experiencing a wide market demand owing to their last longing performing capability along with their accessibility in different bunch of features.
