The valve is installed in the bypass between the flow and return pipes and opens on rising differental pressure to allow flow through the bypass. This maintains the differential pressure between the flow and return pipes at the predetermined set value. Differential bypass valves are used in systems with variable flowrates. Radiator circuits utilising thermostatic radiator valves or heating systems incorporating 2-port control valves are typical applications. Differential bypass valves can be used in both constant and variable volume systems to prevent the differential pressure from rising, which can seriously affect the performance of the 2-port control valves.
