Differential Pressure Bypass Valve for Hydraulic Balance This self-regulating bypass valve maintains a stable water flow, reduces hydraulic disturbances in your heating system, and protects components from excessive pressure. It provides consistent operation across floor heating, heat pumps, and boiler applications, helping extend overall system life. - Compact brass construction: Made from high-quality brass with a space-saving design that fits into existing HVAC configurations. Thread diameter 33 mm; overall height 155 mm; installs without extensive modifications. - Dual scale display: 360-degree visibility with pressure readings in Bar and MH2O units, so you can monitor pressure from any angle. Clear display aids proper setting and ongoing maintenance. - Versatile compatibility: Suitable for floor heating, heat pumps, central heating networks, and air conditioning setups. Adaptable for residential or commercial HVAC configurations. - Use scenarios: New installation of underfloor heating with a heat pump to balance hydraulic flow and prevent noise; retrofit of a boiler-based system to reduce pressure spikes and protect components; integration into a central cooling loop in a commercial building to maintain stable pressure.
