A pressure operated diaphragm type control valve designed to control the flow of a fluid or air by an independent pressure applied to the valve diaphragm
Available either normally open; closed by diaphragm pressure or normally closed; opened by diaphragm pressure.
Diaphragm pressure connection can be indexed to over inlet, over outlet or over either side for maximum hook-up flexibility.
Full port diameter means full capacity and low pressure drop through the valve.
Larger sizes have a fully balanced inner valve for both inlet and outlet pressures up to 250 psi, ensuring operating pressure requirements unchanged by variations in system pressure.
Larger size valve component interchangeablity enables easy changeover from normally open to normally closed or vice versa.
