Structure and characteristics of self operated differential pressure control valve:

The body of ZY47 self operated differential pressure control valve is composed of a dual channel automatic regulating valve that can change the flow resistance and a controller separated by a diaphragm into two independent chambers. One chamber is connected to the return water pipeline. Installed on the return water pipeline during use. The channel automatic regulating valve is an actuator, and its action is powered by the pressure difference between the supply pressure P1 and the return pressure P2. The controller is a differential pressure comparator, which is selected based on the resistance of the controlled heating system. The spring reaction force on the return water side is used to balance the pressure difference between the supply and return water. When some users of the controlled heating system adjust the room temperature and the resistance increases or decreases, it will cause a change in the circulating flow until the pressure on both sides of the diaphragm is balanced, allowing the controlled system to automatically adjust internally.

Installation instructions for self operated differential pressure control valve:

Try not to change the diameter as much as possible, and consider reducing the diameter when the flow rate is too low. The connection of the control valve pressure pipe is 1/2 pipe thread, with a length of 1.5m, and is connected to the water supply pipe. This valve is divided into two types: fixed pressure differential type and adjustable pressure differential type. Nominal pressure: 1.6Mpa, medium temperature 0-120 ℃.

Typical Installation of Self operated Differential Pressure Control Valve ZY47

Key installation points for self operated differential pressure control valve ZY47

1. Self operated differential pressure control valves are divided into three types: supply type, return type, and bypass type. Generally installed on the return pipe, the pressure pipe on the valve is connected to the supply pipe; Water supply pipe installation can also be used, but it cannot be interchanged. The bypass type self operated differential pressure control valve is in a closed state within the rated differential pressure range.

2. Self operated differential pressure control valves can be installed horizontally or vertically.

3. The size of the pressure pipe connector is generally 1/2 "pipe thread, and a variable diameter pipe joint or welded pipe joint should be installed on the water supply pipe during installation.

4. The adjustable self operated differential pressure control valve has a knob for adjusting the differential pressure, which can increase or decrease the set value of the differential pressure.

5. The installation position should be set with straight pipe sections according to the product manual requirements.

6. Prior to installing the self operated differential pressure control valve, additional installation was made in front of the valveGL41HY type filterTo avoid blockage. If it is confirmed that the water quality is clean enough, filters need not be installed.
