Product Details

Applicable Working Conditions

The high-pressure ball valve is mainly suitable for the pipelines of various systems of thermal power stations, cutting off or connecting the pipeline medium.

Applicable Media

Water, steam and other non-corrosive media.

Compared with other valve products, high-pressure ball valves are characterized by high temperature and high pressure, a unique self-sealing design, the higher the pressure is, the more reliable the seal will be. Due to the special performance technical characteristics and special working conditions, the product has formed the characteristics that other products can not replace.

Valves Certificates

Qualified to offer the EN 10204:2004 Type 3.2, it will comply to your TPI or ITP.

Zhejiang Xiongtai valve manufacturing Co., Ltd, High pressure ball valves are qualified to do the Non-destructive testing, such like:Fugitive Emission testing, Radiograhpic testing, Ultrasonic Testing, Magnetic particle testing, Ferrite testing, microstructure E112 testing, etc.

High Pressure Ball Valve Structural Features

1. The anti static design of the high pressure ball valve makes the ball, valve stem and valve body form an electrostatic channel. Therefore, the static electricity generated by the friction between the ball and the bonnet during the opening and closing process can be led to the ground through the valve body to prevent the fire or explosion hazard caused by the static spark.

2. Standard single-piston action (self-relief valve seat), the fluid pressure on both sides of the forward and reverse flow, creating a combined force of thrust, the combined force pushes the valve seat tightly against the ball.

The effect of fluid pressure in the valve cavity creates a resultant thrust, which pushes the valve seat away from the ball. When the valve is in the fully open and fully closed position, any over pressure in the valve cavity, the single piston design can automatically relieve pressure.

Therefore, this valve seat ring is called "automatic pressure relief type".

Optional double isolation and double bleed action

There is fluid pressure at both ends of the inlet and outlet, which is a resultant force in the valve cavity, which pushes the valve seat ring toward the sphere. If the valve is a double-piston valve seat ring, a pressure relief valve is needed to reduce the occurrence of over pressure in the valve cavity.

3. The high pressure ball valves are coordinated with the bracket platform on which the drive device is installed, and the worm gear transmission device, the pneumatic device, the electric device, the hydraulic device and the gas-hydraulic device can be conveniently installed.
