Slow-closing check valve
Slow-closing check valves are used for water supply and drainage pipes. They are installed at the outlet of pumps to prevent medium backflow and eliminate destructive water hammer. They can effectively reduce the pressure of water hammer in valve closure and ensure safe operation. They have light disc, large opening.
Hydraulic electric floating ball valve
Electric floating ball valve is based on remote control floating ball valve installed with normally open solenoid valve electronic control device. The electric floating ball valve has double safety function. Even in the case of power failure or failure of the floating ball, it can control the water level.
Stainless steel solenoid valve
The working principle of the solenoid valve is that there are closed chambers in the solenoid valve. There are through holes in different positions. Each hole leads to different oil pipes. In the middle of the chamber is a valve, and on both sides are two electromagnets. The magnet coil electrifying valve body on which side will be attracted.

Flange open stem gate valve
The opening and closing parts of open-rod gate valve are gates. The moving direction of the gate is perpendicular to the fluid direction. The open-rod gate valve can only be fully opened and closed, and can not be adjusted and throttled.
There are two sealing surfaces on the gate. The two sealing surfaces of the most commonly used mode gate valve are wedge-shaped and wedge-shaped angles, which vary with the valve parameters, usually 50. When the medium temperature is not high, they are 2°52'. Wedge gate valve can be made into a whole, called rigid gate; it can also be made into a gate that can produce slight deformation to improve its workability and make up for the deviation caused by the angle of sealing surface in the process of processing. This kind of gate is called elastic gate.
