The floating ball valve features an elastic sealing ring structure design. When the medium pressure is low, the contact area between the sealing ring and the ball is small, generating a higher sealing pressure to ensure reliable sealing. As the medium pressure increases, the elastic deformation of the sealing ring causes the contact area to expand, enabling the sealing ring to withstand greater medium thrust without damage. The valve stem is designed with an anti-blowout structure, ensuring that it will not be ejected by the medium even under extreme conditions such as abnormally high valve cavity pressure or packing pressure plate failure. Additionally, the valve stem incorporates a bottom-mounted seal design, where the sealing force of the reverse seal increases with rising medium pressure, ensuring reliable sealing under various pressure conditions.

The valve stem employs a V-shaped packing seal structure, effectively converting the compression force from the packing gland and medium pressure into the sealing force of the stem.

The traditional packing gland has been improved to a two-part structural design consisting of a packing pressure plate and a packing pressure sleeve. The pressure plate and the sleeve are in spherical contact, ensuring the packing gland remains consistently vertical. A PTFE bushing is incorporated within the packing gland to prevent scratching and wear on the stem and the packing gland, thereby reducing the valve’s operating torque.

Based on user requirements, a disc spring packing compression mechanism can be employed to enhance the reliability of the stem packing seal.

The specially processed ball and seat are particularly suited for high-temperature media containing dust and solid particles.
