Kofloc Model 6610 Pressure Regulator Valve controls the pressure applied to the flow to keep it constant or reduce the pressure during flow control. Pressure-regulating valves are classified into reducing valves and back-pressure valves. Reducing valves make the outlet-side pressure constant when the pressure on the inlet side changes, and are used at the first stage of systems in general. Meanwhile, back-pressure valves are a kind of constant-volume relief valve that removes gas while keeping the primary-side pressure constant.
This valve has been developed for better repeatability and quick, reliable pressure regulation by increasing the accuracy of the low-pressure side compared with the Model 6600. It is ideal for high-sensitivity analyzers and semiconductor manufacturing equipment, as well as for research and development.
