TRUNNION BALL VALVE
Trunnion ball valve is a non-threaded ball type design. It has a supportable ball cage valve, and it has a supportable valve that allows rotation on its shaft. The steel body with external thread or internal thread is composed of a seal at the other end. The utility model adopts an ear type shaft ring without installing a guide rod and a valve seat, which ensures the small volume, light weight and convenient installation of the valve. Trunnion type is applicable to all kinds of liquids or liquids with almost no ball.
Product Description:
the trunnion connecting ball valve is a non threaded ball type design. It has a supportable ball cage valve, and it has a supportable valve that allows rotation on its shaft. The steel body with external thread or internal thread is composed of a seal at the other end. The utility model adopts an ear type shaft ring without installing a guide rod and a valve seat, which ensures the small volume, light weight and convenient installation of the valve. Trunnion type is applicable to all kinds of liquids or liquids with almost no ball.
Trunnion ball valve is an easy to install and replace ball valve. Good sealing performance, high ball valve requirements, can be used at a wide range of temperatures, and the pressure is low at the ambient temperature. Trunnion type ball valve can meet the pressure of high pressure and high temperature below 2000 ℃ without damage or deformation.
The valve body is a trunnion valve commonly used in the industrial field, especially an operating valve in the oil and natural gas field. TBV is mainly composed of valve body cover and valve cover. The cover trunnion is connected with the valve body. During the process, the load of the entity is reduced and fixed through the control rod between the cover trunnion and the seat ring. One or more central positions relative to the ball in the fixed hole shell are provided to pass through.
Product advantages:
Ideal for trunnion valves and water systems, their design of up to 10 GPM makes them easy to flow and move, and they are light to handle, and can also work in the environment. Include a large one. Working flanges can be used in a wide range of applications, so you can rely on them in almost any application.
Trunnion type is applied because of its designed processing capacity, processing type of sphere, shape and height of size. They can be ordinary, and they can have graphs; There are various end connections and separate pressure tests are carried out before leaving the factory.
Axial ball valves are designed for a wide range of applications, from basic opening / control to complex ear reactive pressure and temperature control. As the first flow valve, such as trunnion design, our valve is ideal for applications with limited space and special angles when installing equipment. The trunnion ball can withstand the most severe working conditions.
Product design:
Trunnion ball valves are ideal for controlling movement from one area or process system to another. This is the compound direction of the ball in the trunnion raceway. This unique design option allows the pipe to be rotated back and forth to the full position in any direction, allowing the pipe to be connected at any angle that needs to be closed.
Trunnion Ball and butterfly valves these heavy-duty valves are designed for convenience and can be used to close or open, with a variety of configurations combined with your position. They are usually used for elbow flanges and well locations. It can be installed as a pre filter or wherever a ball valve is required.
The valve body is designed to completely isolate the flow of the process flow and facilitate port control. The full size range of valve body type provides a full range of products, and can provide various heights to adapt to actuators in different places. And can provide a variety of available options, allowing you to choose the style that best meets your needs.

The trunnion ball valve is an essential device for regulating the flow of fluids- steam, gas, or oil in pipeline. It is quarter-turn designs with a ball capable of rotating 90 degrees on its axis to either block or allow the flow of fluid. These valves have a spherical disk design at the center, which rotates to regulate the start-stop flow cycle. The disk often called the ball comes designed with a small protruding shaft at the top and bottom which are mechanically supported. In this case, flow is controlled by the position of a hole in the center of the ball. For their versatility, Trunnion mounted ball valves are useful in industries where such shut-off operation is required.
