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. <p><p> They 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. <p><p> <strong> Features & Benefits: </strong> <br> <ul> <li> Valves are installed in the bypass between the flow & return pipes & opens on rising differental pressure to allow flow through the bypass. This maintains the differential pressure between the flow & return pipes at the predetermined set value. <br></li> <li> The valve has compression ends complying with BS EN 1252-2 for use with R250 (half hard) copper tube. <br></li> <li> The force is adjustable by turning the control knob to set the required differential pressure between 1 to 5 m head (10 to 50 kPa) for the angle valve and between 1 to 6m head (10 to 60 kPa) for the straight valve. <br></li> <li> The eres differential bypass valves use a stainless steel compression spring to exert a predetermined force onto the disc. <br></li> <li> The straight valve has a protective dome to conceal the scale and adjustment mechanism. <br></li> </ul>
