Extended Stem Gear Flange Butterfly Valve

Gear Flange Floating Ball Valve (Extension rod) is used to cut off or connect media in pipelines, as well as regulate and control fluids. As a professional custom valve manufacturer, Waits Valve has always been at the forefront of fashion and has leading technology. If there is anything that needs to be innovated, please feel free to contact us at any time!

Waits valves can provide you with various floating ball valves and fixed ball valves.

The main characteristics of ball valves are compact structure and reliable sealing. The sealing surface and spherical surface are usually in a closed state,

This means that it is not easily eroded by media and is easy to operate and maintain. NAI LOK is a professional ball valve supplier and valve manufacturing company, selling various types of ball valves. We specialize in manufacturing manually cast and forged ball valves of various special alloys, suitable for conventional working media such as water, solvents, acids, and natural gas, as well as harsh working environments.

Product Features

The Gear Flange Floating Ball Valve (Extension rod) is designed with an outward swinging valve body that complies with ASME Class 800 product standards.

All pressure bearing components adopt a fully forged structure.

The valve is connected by a flange, and the flange is integrally formed with the closing component.

The standard main sealing gasket is designed as OR AED type and always provides secondary emergency sealing to meet fire protection requirements.

High quality packing ensures reliable sealing and low emission performance.

The Gear Flange Floating Ball Valve (Extension rod) uses low seat friction materials and surface smoothness to ensure reliable sealing and a long service life.

The optimal CV value.

The valve body closure connection adopts a standard split bolt connection design.

We use a low operating torque design.

Static conductive springs (anti-static devices) are standard between the valve stem and the sphere.

Anti blowing valve stem design.

Introducuction:

The Gear Flange Floating Ball Valve (Extension rod) is a quarter turn valve that uses a hollow, perforated, and rotatable ball (known as a floating ball) to control the flow rate through the ball.

The floating ball valve utilizes natural pipeline pressure to compress and seal the ball onto the downstream valve seat. The sphere is suspended in a flowing medium (floating) and held in place by the compression of two valve seats.

When the ball hole is aligned with the flow direction, the sphere opens; When the valve handle is rotated 90 degrees, the ball closes. Floating ball valves are durable and can maintain good performance even after multiple uses. They are also reliable and can be safely closed even when not in use for a long time.

The Gear Flange Floating Ball Valve (Extension rod) is designed to achieve bidirectional closure.

As the size of the valve hole increases, the area that can withstand pipeline pressure will also increase. This will result in an increase in the force acting on the sphere.

When the valve seat reaches the critical point, the ball will no longer be able to support the ball, and other designs need to be considered: floating ball valves are usually not suitable for large-sized and high-pressure applications. Floating ball valves are not suitable for throttling purposes.
