Tamperproof bypass valve
This bypass valve from Inta is designed to avoid those without sufficient plumbing knowhow adjusting its setting. The transparent cap is retained by a grub screw to avoid changes to the system setup after initial commissioning.
Flow is automatically stabilised when circulating pressure begins to rise in a system with thermostatic radiator valves. This helps to prevent the pump pumping against a closed head. It also improves the efficiency of the boiler and increases the life of system components.
Inta valves have 22 mm compression fittings and are available in straight and angled variants.
