AGH flow regulating valve is a specially designed valve, which can be adjusted by a scale handwheel. Gas or ambient temperature air can be transmitted to regulate the flow in a linear way to protect the safe operation of equipment.

operational principle:

Flow limit: When the medium flow exceeds the set value, the valve will automatically close to prevent excessive flow from damaging the burner.

Safety protection: in the case of abnormal high pressure, the valve will cut off the fluid to avoid equipment overload or damage.

design feature

Forced sealing design: Similar to the traditional stop valve, the AGH type valve requires pressure to be applied when closed to ensure sealing and prevent leakage.

Valve disc and seat structure: usually use conical or flat sealing surface to ensure good cutting performance.

Flow sensing mechanism: May be equipped with a flow sensor or mechanical regulator to monitor and control the upper limit of flow.

merit:

Quick cut to protect equipment safety.

The structure is relatively simple and easy to maintain.

Suitable for high pressure and high temperature environment.

Installation and maintenance precautions

Flow direction: When installing, ensure that the medium flow direction is consistent with the valve body marking direction. Usually, "low inlet high outlet" or "high inlet low outlet" design is adopted, depending on the pressure level.

Avoid particle media: not suitable for fluids containing solid particles, high viscosity or coking, so as not to affect the sealing performance.

Periodic inspection: the sealing surface and valve stem should be maintained to prevent leakage due to wear or corrosion.

application scenarios:

Combustion system: used for gas burner to prevent safety accidents caused by flashback or abnormal flow.

Compressed air system: protect diaphragm pump and other equipment from excessive flow impact.

Chemical and energy industry: flow control for high pressure or corrosive media.
