800X Differential pressure bypass balance valve
Product overview
The differential pressure bypass valve is composed of hydraulic control valve main valve, differential pressure pilot valve and piping. It is a valve used to balance the pressure difference between the water supply and return water in the main pipe of air conditioning system. The valve can improve the utilization rate of the system, protect the safety of the system, and reduce the noise of the system and the damage to the equipment caused by excessive pressure difference.
