Ductile Iron Differential Pressure Bypass Valve 800X-16Q

Product Description

The 800X Differential Pressure Bypass Valve is a valve used between the supply and return water lines in HVAC systems to balance pressure differentials. This valve optimizes system efficiency, maintains a constant pressure differential, reduces system noise, and prevents damage to equipment caused by excessive pressure differentials. What sets the 800X differential pressure bypass valve apart from other balancing valves is that it lacks an actuator; instead, it relies on the pressure differential of the medium itself to balance the system, thereby saving energy and installation space. It is a smart valve.

Structural Features and Applications

The 800X differential pressure bypass valve consists of a main valve, a differential pressure control pilot valve, a needle valve, a ball valve, a strainer, and a pressure gauge, forming a hydraulically controlled piping system. Through a specially designed pilot valve control chamber, pressure change signals are compared to generate a signal that controls the opening of the main valve, thereby maintaining the inlet and outlet pressure differential of the main valve at a preset value. This product utilizes self-acting hydraulic control, requiring no additional devices or power sources, and is easy to maintain. This series of valves is used in water supply network systems for high-rise buildings, residential areas, and other similar applications, as well as in municipal water supply projects.
