Top entry ball valve fixed the shortcomings

of the spring preload can not be adjusted and controlled, and large compression spring assembly, the assembly difficult. To solve this

problem, instead of the spring material selection ANSI 302 304. ANSI 302 spring stiffness, corrosion resistance and 304 close. Furthermore,

the increase of the spring seat and adjust the nut, the cylindrical valve seat and spring seat are turning screw, adjust the nut with a

compression spring within the spring seat, the seat assembly into the valve body. As the installation prior to spring ball has been

compressed, so the ball valve is very easy to install. When the ball assembly, it will

adjust the nut out the spring seat, this time the spring preload of smaller spheres. If you want to increase the preload adjustment nut can

be adjusted.
This new  ball valve is an innovative
solution for gas, sewer and water applications where metal ball valves
have typically been installed.

The  ball valve is 50 percent lighter than comparable metal valves
and offers corrosion resistant internal and external parts.

Available in
1" through 6", the new  ball valve boasts a two-step planetary
gear system to ensure smooth opening and

closing of the valve, thereby
eliminating water hammer.
