The theoretical flow characteristic curve is an equal percentage characteristic curve

When the operation regulation of the system adopts centralized regulation (such as variable speed regulation of water pumps)

Balance valve is a regulating valve with a special digital locking function. It adopts a DC valve body structure and has better equal percentage flow

The balance valve itself has no special features, only in terms of its functional and field differences.

When water is injected into the pipe, the plug stays in the open position for a large amount of exhaust.

The float of the exhaust valve is made of low-density PPR and composite materials, which will not deform even if soaked in high-temperature water for

When there is gas overflow in the system, the gas will climb up the pipeline and eventually gather at the highest point of the system.

All parts of this valve are forgings, and forging is strictly carried out in accordance with the forging process specifications and process cards.

The disc of the swing check valve is in a circular shape and rotates around the axis of the valve seat channel.

Check valves can also be used on pipelines that provide supply to auxiliary systems whose pressure may rise above the system pressure.

A check valve refers to a type of valve with a circular valve disc as the opening and closing component, which acts to block the backflow of the mediu
