Floating ball valve adopts elastic seal ring structure design. When the medium pressure is small, the sealing ring and the ball contact area is small, in the sealing ring and the ball contact to form a larger sealing pressure, to ensure reliable sealing. When the medium pressure is large, with the elastic deformation of the sealing ring, the sealing ring and the ball contact area increases, so the sealing ring can withstand a larger medium thrust without damage.

The valve stem adopts the design of anti-blowout structure, which can ensure that the valve stem will not be blown out by the medium even under the extreme conditions of abnormal pressure rise in the valve cavity and failure of the packing pressure plate. The valve stem adopts the down-loaded structure design with sealing, and the sealing force of inverted seal increases with the increase of medium pressure, so it can ensure the reliable sealing of the valve stem under all kinds of pressure.

The valve stem adopts V-shaped packing seal structure, V-shaped packing can effectively transform the packing gland compression force and medium force into the sealing force of the valve stem.

The traditional packing gland is improved to a two-body structure design of packing pressure plate and packing pressure sleeve, the packing pressure sleeve and the packing pressure plate adopts spherical contact to ensure that the packing pressure sleeve is always vertical, and PTFE bushings are set inside the packing pressure sleeve to avoid the abrasion and wear of the stem and the packing pressure sleeve, and to reduce the operating torque of the valve.

According to the user's needs, a disc spring-loaded packing compression mechanism can be used to make the sealing of the stem packing more reliable.

The ball and seat treated with special technology are especially suitable for higher temperature and media containing various dust and solid particles.

1. the use of specially designed compensating movable metal valve seat structure, reliable sealing.

2. this series of ball valves should be used in accordance with the specified flow direction. 3.

3. this series of ball valves can be equipped with a variety of driving devices.
