ESI 22mm Straight Brass Automatic Bypass Valve ESABV22S

ESI 22mm Straight Brass Automatic Bypass Valve ESABV22S. This product is used to maintain the water flow in central heating systems when fitted with thermostatic radiator valves to meet Part L of the building regulations. This reduces noise and also reduces wear and tear on system components. With this valve, you can ensure a constant flow through the boiler. It also features a high capacity flow, up to 50 litres per minute, as well as a wide differential range, 0.05 to 0.5 bar. It is also quick and easy to install thanks to its 22mm compression fittings.
