Zwicky Regulating Valves

Controlled Pressure Regulating Valves


The operation of this valve is designed to react to variations of pressure at a constant and predetermined level.

It remains closed while the fluid pressure upstream of the valve builds up to the predetermined datum level which any further increase in pressure will act upon the underside of the diaphragm and cause the valve to open. The valve will continue sensitively thus to regulate the pressure on the line upstream of it, opening and closing acoording to the pressure acting upon the diaphragm.

Zwicky Regulating
