A reliable 22 mm automatic bypass valve is essential for any heating system that uses thermostatic radiator valves (TRVs) or zone valves. Designed for boiler‑radiator loops, this premium valve keeps the pressure steady and guarantees a minimum flow of up to 50 L/min, protecting your pump and boiler heat exchanger from wear and noise.
Key benefits
– Wide differential pressure range: 0.1 – 0.6 bar ensures smooth operation as TRVs close.
– Noise reduction: Maintains even system pressure, eliminating the “click‑clack” of closing valves.
– Pump & boiler protection: Constant flow prevents impeller strain and extends heat‑exchanger life.
– Lockable set pressure: Turn the adjustment head to the desired setting and secure it with the top screw for a hassle‑free fix.
Installation made simple
1. Place the valve in a loop between the pump’s flow and return lines (follow the arrow on the body).
2. Adjust the head until the required pressure number appears, then lock it in place.
3. Verify settings against your boiler’s manual and the flow‑rate chart provided.
With its 22 mm compression fittings and boxed delivery, this valve is ready for quick fitting in any residential or commercial heating circuit that needs a reliable boiler bypass. Keep your system quiet, efficient, and long‑lasting with this straightforward solution.
