Product Features:

1.Top Entry Design: One of the outstanding features of the top entry ball valve is that the key components such as the valve stem and ball can be removed from the top of the body, without disassembling the entire valve or affecting the pipeline system, which greatly reduces the maintenance difficulty and cost, as well as shortens the repair time.

2.Quick Replacement: When parts need to be serviced or replace, the top entry design makes the operation easier and faster, increasing work efficiency.

3.Large Flow Area: The ball design makes the valve has a large flow area in the full open state, which reduces the resistance of the medium at the valve, and improves the flow efficiency of the pipeline system.

4.Reasonable Flow Tunnel Design: The flow tunnel design of the top entry ball valve is reasonable, which can effectively reduce the deposition and blockage of the medium at the valve, and extend the valve service life.

5.Various medium: Top entry ball valve can be applied to various medium, including water, steam, oil, gas, etc., to meet the needs of different industrial fields.

6.Long Service Life: The structure of the top entry ball valve is simple and reliable with the long service life, which can operate stably under various conditions.

7.Anti-static Design: The electrostatic extraction device of spring and small ball is used to form an electrostatic channel between the ball and the valve body through the valve stem, so that the static electricity caused by the friction between the ball and the sealing ring is led to the earth through the valve body, which can prevent fire or explosion and other hazards caused by electrostatic sparks.

8.Sealing Emergency Rescue and Valve Lubrication: When the valve seat and stem seals are damaged and leaked, the sealing grease injected by the grease injection valve can achieve instantaneous sealing. In normal operation, the valve stem and ball can be lubricated by injecting grease to make the valve opening and closing more flexible and convenient.

9.Middle Cavity Self-pressure Relief Function: When the pressure in the valve cavity is abnormally elevated, the piston valve seat structure can ensure that the pressure in the valve cavity is pushed away from the valve seat, so that the pressure in the valve cavity is released to ensure the safety of the valve.

10.Actuator Mounting Platform Setup: The flange of the top entry ball valve is designed according to ISO 5211, which allows easy installation of any type of actuator by means of brackets and coupling sleeves.
