Description

The valves are 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 returnThe valves are 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.

Design
The eres differential bypass valves use a stainless steel compression spring to exert a predetermined force onto the disc.
The force is adjustable by turning the control knob to set the required differential pressure between 1 to 5m head (10 to 50 kPa) for the angle valve and between 1 to 6m head (10 to 60 kPa) for the straight valve
The straight valve has a protective dome to conceal the scale and adjustment mechanism.
The valve have compression ends complying with BS EN 1252-2 for use with R250 (half hard) copper tube.
