Products Description

Newlotoke Trunnion ball valves are widely used valves to control flow and pressure. They are commonly used in piping systems that transport liquids or gases. The biggest advantage of ball valves is that they can be opened and closed quickly, making them very useful in responding to emergencies.

Fixed ball valves are composed of balls, stems and valve bodies. The sphere is usually spherical or hemispherical, and the stem is fixed on top of the sphere. When the stem rotates, the ball rotates with it, controlling the flow in the pipe.

There are many types of fixed ball valves, including one-way ball valves, three-way ball valves, four-way ball valves, etc. Among them, one-way ball valves only allow fluid to flow in one direction, while three-way ball valves and four-way ball valves can be used for diverting and mixing fluid flow.

The advantage of fixed ball valves is that there are no extra connection points between the stem and the ball, so there are few air leaks or leaching during operation. The spheres are usually made of wear-resistant reinforced materials, which have good corrosion resistance and wear resistance.

Fixed ball valves are widely used in various industrial and civil pipelines, such as electric power, petrochemical, papermaking, chemical, water conservancy and other fields. In water treatment, ball valves are often used to control flow and pressure to support farmland irrigation, urban water supply and underground drainage.

In general, as a common valve type, fixed ball valve has the advantages of simple structure, convenient use and durability, and has a wide range of applications.

Design Feature

◆ It adopts cylindrical spring or wave spring preloaded movable metal valve seat structure, reasonable sealing pre-tightening force design, flexible closing and opening, effectively ensuring the reliability of sealing.

◆ The valve stem with a special structure device not only ensures that the filling material will leak, but also prevents the valve stem from coming out.

◆ According to the needs of users, it can be designed to adapt to the structure of dust (including solid particles), slurry and other media, so that the ball valve has better wear resistance and high temperature resistance.

◆ It has fire-proof and anti-static function.

◆ The structure of the ball valve should be used in accordance with the specified flow direction.
