It opens automatically as system pressure rises when thermostatic radiator valves or zone valves close, so water keeps circulating through the boiler or heat pump and the pump isn't left running against a closed head. The opening point is set on a visual dial on the valve body. Choose the straight (in-line) ABPS28CP or the angled (90°) ABPA28CP to suit your pipe run.\u003c\/p\u003e\n\u003ch3\u003eKey points\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eAutomatic differential pressure bypass, no electrical connection needed\u003c\/li\u003e\n\u003cli\u003eAdjustable setting 0.1 to 0.5 bar with a visual dial\u003c\/li\u003e\n\u003cli\u003eStabilises circulation, flow rate and pump pressure\u003c\/li\u003e\n\u003cli\u003eProtects the pump and maintains minimum flow through the heat source\u003c\/li\u003e\n\u003cli\u003e28mm compression connections, straight or angled pattern\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eWhat's included\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e1 x Inta 28mm automatic bypass valve in your chosen style\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eSpecification and price\u003c\/h3\u003e\n\u003ctable\u003e\n\u003cthead\u003e\u003ctr\u003e\n\u003cth\u003eStyle\u003c\/th\u003e\n\u003cth\u003eInta code\u003c\/th\u003e\n\u003cth\u003eConnections\u003c\/th\u003e\n\u003cth\u003ePrice (inc VAT)\u003c\/th\u003e\n\u003c\/tr\u003e\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003eStraight\u003c\/td\u003e\n\u003ctd\u003eABPS28CP\u003c\/td\u003e\n\u003ctd\u003e28mm compression\u003c\/td\u003e\n\u003ctd\u003e£19.99\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eAngled\u003c\/td\u003e\n\u003ctd\u003eABPA28CP\u003c\/td\u003e\n\u003ctd\u003e28mm compression\u003c\/td\u003e\n\u003ctd\u003e£22.99\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003ctable\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003eDifferential pressure range\u003c\/td\u003e\n\u003ctd\u003e0.1 to 0.5 bar\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eFlow capacity\u003c\/td\u003e\n\u003ctd\u003e1 to 5 m³\/h\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMax inlet pressure (dynamic)\u003c\/td\u003e\n\u003ctd\u003e10 bar\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMax inlet temperature\u003c\/td\u003e\n\u003ctd\u003e100°C\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003ch3\u003eOptions\u003c\/h3\u003e\n\u003cp\u003eSelect \u003cstrong\u003eStraight\u003c\/strong\u003e for an in-line fit or \u003cstrong\u003eAngled\u003c\/strong\u003e for a 90° fit using the Style selector.
