Diaphragm valve 514/515

The manually actuated diaphragm valve from GF ensures a safe and precise setting of the liquid flow and shuts off the passage completely, if required. A plastic housing gland ensures a corrosion-free connection to the housing of the valve.

The diaphragm separates the moving parts from the medium to be transported. A constricted passage ensures an accelerated linear flow.

As standard the GF diaphragm valve is equipped with a lockable handwheel and a two-colour position indicator.
The 514 Series has a gland fitting, the 515 Series a glue fitting.
