main feature

1. The three-way ball valve adopts an integrated structure, a 4-sided valve seat sealing type, fewer flange connections, high reliability, and a lightweight design.

2. The three-way ball core is divided into T shape and L shape, with long service life, large circulation capacity and small resistance.

3. Ball valves are divided into two types: single-acting and double-acting. The characteristic of the single-acting type is that once the power source fails, the ball valve will be in control system requirements.

Chief Features

The specially designed V-shaped ball has strong shearing effect and sealing performance on the medium, and can adjust the flow characteristics of the medium in equal proportion

The valve meets NACE standard, fugitive emission function and fire test certification of API Spec 607

API 622 certified live loading of packing makes valve stem sealing safer

The spherical surface can be hardened by hard chromium plating, desalination, supersonic spraying and other sealing surface hardening processes to increase the hardness, wear resistance and corrosion resistance of the sealing surface

The valve seat spring is designed with clip spring, which can provide preload for the valve seat seal and greatly reduce the torque required to drive the valve

Due to the shear force between the V-shaped opening and the valve seat, and the smooth and round flow channel in the valve cavity, the medium is not easy to accumulate in the cavity, so it is more suitable for the system control of medium with fiber and solid particles besides liquid medium

main feature

1. It has an elastic load pressure auxiliary sealing seat to ensure close contact between the valve seat and the ball core.

2. It?has an integral valve body structure and there is no possibility of potential leakage?.

3. It has equal percentage characteristics and a wide range of The control range and particularly stable control process can be widely used in a variety of processes.

4. The valve stem and the ball core are connected by involute splines. When the tooth profile is loaded, there is a radial force on the tooth that can automatically Centering effect, and each tooth is evenly stressed, making it high strength and long life.

main feature

1. Its structure adopts the eccentric tightening principle to achieve the purpose of gate tightening, adjustment and closing through the transmission mechanism. The sealing pair is a metal surface ring with a hard surface contact seal, double offset

When the core structure is opened, the valve core is located in the ball chamber, with a large flow cross-section, and the valve will not be washed. When closed, the valve core will not be washed. When it is opened, the spherical surface of the valve core will move along the valve.

The seat is progressive, effectively removing scaling obstacles and achieving reliable sealing.?It is particularly effective for mixed flow transportation of two-phase mixed flow where solids prone to scaling are precipitated.

2. The hemisphere of the valve is made of bimetal, and different alloys are overlayed on the base metal. The valve seat is also overlayed accordingly. After special treatment, the sealing surface is combined into an anti-corrosion, wear-resistant, high-performance sealing surface.

Various types such as strength to meet the needs of different occasions.

3. It is tightly sealed and can transport harmful gases with zero leakage.

4. There is a compensation amount left in the valve core of the sealing pair. When the valve is worn, rotate it a little when closing to ensure reliable sealing and extend the service life.?Additionally, users will

The compression nut is unscrewed and the valve seat can still be used after adjustment or replacement, thus avoiding the disadvantage of scrapping the entire unit if the valve seal fails.
