The difference between side mounted ball valves and top mounted ball valves

Side mounted ball valves generally refer to valves where the valve core ball is installed from the side of the valve during valve installation. The ball and seat sealing rings of the side mounted hard sealed ball valve are made of metal materials, and the sealing pressure ratio is very high. Relying on the pressure of the medium itself cannot meet the sealing requirements, and external force must be applied. This type of valve is suitable for high temperature and high pressure media.The main Ball valve product names of China Ball valve Network include:Forged Brass Ball Valve (Butterfly Handle Type)，Forged Steel Anti-sulfur Fixed Ball Valve，GB/ANSI Three-way Ball Valve，GB/ANSI High Pressure Forged Small Ball Valve，GB Cast Steel Fixed Ball Valve，GB Forged Steel Fixed Ball Valve

Side mounted floating ball valve, also known as side mounted soft sealed floating ball valve, refers to a floating ball (elastic ball) that is formed by opening an elastic groove at the lower end of the inner wall of the ball to obtain elasticity. When closing the channel, use the wedge-shaped head of the valve stem to expand the ball and press it against the valve seat to achieve sealing. Release the wedge-shaped head before rotating the sphere, and the sphere will return to its original shape, creating a small gap between the sphere and the valve seat, which can reduce friction and operating torque on the sealing surface.

The difference between side mounted ball valves and top mounted ball valves lies in which part of the valve body the ball is installed into, whether it is installed from the side or top of the valve. The ball valve with a valve core installed from the top is called a top mounted ball valve. Top mounted ball valves are mainly used on long-distance pipelines, such as the West East Gas Pipeline When repairing this type of valve, the valve core ball can be removed for maintenance or replacement without removing the entire valve from the pipeline

Top mounted ball valve product features:

1. Integrated valve body design, upper pivot fixed support, flange structure.

2. Integrated pivot fixed club design.

3. Double blocking release function.

4. The high-strength integral club structure ensures precise positioning of the sphere.

5. The pivot adopts an anti blowing protection structure.

6.2 sets of O-ring seals, combined with fire-resistant packing structure on the valve stem, effectively prevent leakage.

7. Corrosion resistant, low friction coefficient bearings.

8. The nickel corrugated spring allows the nylon sealed metal valve seat to move towards the ball, providing bidirectional sealing for both the inlet and outlet.

9. The superior performance of standard nylon and PEEK valve seats ensures effective sealing under low pressure conditions.

10. The design of the sealant holder allows for the insertion of sealant in emergency situations to seal the valve stem or seat.

11. Adopting unique retractable valve seat technology, the ball rod, valve stem sealing ring, metal valve seat, and corrugated spring can be replaced online.

Reduce torque to a minimum for easier valve operation.

13. A high-performance anti-static grounding device that effectively contacts the ball club and valve body.

14. Pre installed drive device platform and screw holes, ready to assemble the drive device at any time.

15. Fire prevention function: When the valve seat is burned or damaged, the metal valve seat automatically adheres to the ball, resulting in a small leakage between the valve seat and the ball.
