Kombi-3-plus dynamic differential pressure balancing valve

HoneywellKombi-3-Plus Dynamic Differential Pressure Balancing ValveIt is a commonly used product for pressure difference control in HVAC water supply systems, which includes red or black valves for water supply pipes, blue valves for return pipes, pressure difference control bellows, and pressure tapping pipes. The Honeywell Kombi-3-Plus series dynamic differential pressure balancing valve is widely used in branch pipelines and end devices of HVAC water systems, and can also be applied to other occasions with the same or similar functional requirements. The Honeywell Kombi-3-Plus series dynamic differential pressure balancing valve can dynamically respond to and balance changes in system differential pressure, thereby maintaining a constant pressure difference at two key points in the pipeline. The pressure difference control diaphragm box installed on the blue valve senses the pressure from the red valve, black valve, and blue valve on the upper and lower sides of the diaphragm. When the pressure change at any end causes a change in the diaphragm sensing pressure difference, the position of the valve core of the blue valve will change accordingly. Adjust the pressure difference at the two ends of the key point until it reaches a new balance with the set pressure difference.

feature

The red valve has functions such as shut-off, flow pressure difference measurement, water injection, and drainage

Black valves can replace red valves and have functions of shut-off, water injection, and drainage

The blue valve has functions such as shut-off, flow pre adjustment, water injection, and emptying, which can be controlled by pressure differenceAfter the membrane box is connected, it has the function of dynamic pressure balance

PTFE sealing seat and annular sealing ring ensure that the entire valve body does not leak, without the need for maintenanceMaintenance and upkeep

The blue valve can accurately display the actual opening of the valve, ensuring precise adjustment

The red copper valve body ensures that the valve has high corrosion resistance
