What are the characteristics of all welded ball valves?


All welded ball valves feature:


1, no maintenance, adjustment and lubrication, easy to install, long-term reliable operation under low operating costs. The surface is spray-coated and has a beautiful luster and is at the leading level in China. There will be no external leakage. The valve body is welded, so the valve is light and easy to insulate. Installation of the adjustment mechanism is very simple, the operating handle can be removed and reversing.


2. Since the valve seat is composed of carbon fiber reinforced Teflon seal ring and disc spring, it has strong adaptability to changes in pressure and temperature, and does not cause any slippage within the marked pressure and temperature range.


3. The processing of the sphere has advanced computer detector tracking and detection, so the processing precision of the sphere is high.


 


4. Since the valve body material is the same as the pipe material, there will be no uneven stress, and it will not be deformed due to earthquakes and vehicles passing through the ground. The pipeline is resistant to aging.


5, large diameter all welded ball valve, equal diameter and variable diameter channel, using fixed ball and floating ball, double piston effect sealing system, automatic


Inject sealant bearings.


6. In order to prevent static electricity, steel ball and spring are respectively installed between the valve stem and the ball body and the valve stem and the stuffing box, which can keep the conductive parts of all parts of the fluorine-filled ball valve and the valve body, let the current pass through the area, and discharge static electricity. Not only prevent fires, but also prevent corrosion and achieve temporary cuts for timely maintenance.


7. The valve stem anti-off function is because the valve stem is affected by the pressure inside the valve, and the force is always generated. Therefore, the valve stem is designed to prevent the structure.


8. Push the pressure washer to the valve stem with a low-friction material thrust washer support so that the valve stem only transmits torque.
