ESI Controls Central Heating Automatic Bypass Valve Angled 22mm - ESABV22

The ESABV22 angled automatic bypass valve from ESI is for use as a boiler or system bypass. Used to maintain water flow in a central heating system fitted with TRV's, the valve keeps a minimum flow rate to minimise circulation when valves are fully or partially closed. Not only does this reduce system noise caused by the closing of radiator valves and motorised valves, it helps eliminate wear and tear on circulating pumps and protects the boilers heat exchanger. This additionally has energy saving benefits.
