The 2/2-way valves of the GB-series are suitable for general applications and is not dependent<br />

operationally on a specific minimum differential pressure. They are ideal choice for installation in<br />

situations where differential pressure fluctuate greatly and are not possible to determine precisely in<br />

advance. They are also suitable for use in heating and cooling circuits.<br />
