Product Overview


Products Description

The 800X differential pressure balancing valve is a valve used to balance the pressure difference between the supply and return water of an air conditioning system. This valve can improve the utilization rate of the system, maintain a precise and constant pressure difference, and minimize system noise and equipment damage caused by excessive pressure difference. The advantage of the 800X differential pressure balance valve over other balance valves is that it does not have an actuator and relies solely on the pressure difference of the medium itself to achieve the function of the balance system, saving energy and installation space. It is an intelligent valve.

Structural characteristics
1. The valve body adopts a full channel and streamlined design, with low fluid resistance and high flow rate.

2. The connection between the body, cover, and piston rod is double sealed by a sealing gasket and a sealing ring, with no external leakage.

3. The valve body, piston cylinder, and piston are double guided, ensuring smooth and reliable movement.

4. All stainless steel piston cylinder, integral cast piston, NBR sealing ring. The perfect combination greatly extends the service life.

5. Introducing advanced technology for detachable valve seats, with clever structures, innovative ideas, and convenient maintenance and replacement.

6. For piston cylinders with guide holes, increase the resistance appropriately to make the piston movement more stable.
