BUNDOR 800X Control Valve 9308-621c
800X control valve 9308-621c
This valve can increase the utilization factor of a system, maintain the pressure difference at a precise constant value, and maximally reduce the system noise and avoid damages caused to the equipment because of an excessive pressure difference. The 800X control valve 9308-621c excels over other balance valve in the fact that it does not have an actuating mechanism, depends entirely on its own pressure difference to realize the function of balancing the system. Accordingly, our pressure difference balance valve saves energy and requires little installation space, thus can be regarded as an intelligent valve.

The role and purposes: for air-conditioning system supply / return water, ensure differential pressure between supply and return water, improve system utilization. To maintain the exact pressure utilization, reduce system noise as well as damage to equipment caused by excessive differential pressure.
