Product Introduction

LYV® floating ball valves are meticulously engineered to ensure superior quality and performance. Our stringent manufacturing processes and quality control measures result in products that outshine similar offerings in the industry. These floating ball valves meet multiple international standards such as API-6A, API-6D, ASME-B16.34, and ISO-17292. Additionally, they have obtained the API-6FA fire certification, making them suitable for applications requiring fire safety. LYV®'s floating ball valves are equipped with high-quality sealing solutions, allowing them to operate reliably in high-pressure and high-temperature environments. We offer a range of sealing options to meet diverse operational requirements. Please contact our dedicated sales team to discuss your specific needs, and we will tailor a floating ball valve solution that meets your unique requirements.

What is Floating valve:

A floating ball valve is one where the ball is not held in place by a trunnion. In normal operation, this will cause the ball to float downstream slightly. This causes the seating mechanism to compress under the ball pressing against it. Furthermore, in some types, in the event of some force causing the seat mechanism to dissipate (such as extreme heat from fire outside the valve), the ball will float all the way to metal body which is designed to seal against the ball providing a somewhat failsafe design .

How does it work(sealing):

The floating ball valve is a common type of ball valve. Its working principle is that the ball itself does not directly contact the valve body, but seals against the valve seats. When the valve is open, the ball can float freely under the influence of the media flow, reducing friction between the ball and valve seats. Since the ball can float freely, the valve seats need to have a certain clearance, and this structural design gives the floating ball valve excellent sealing performance.

Why choose LYV®️ valves:

We produce ball valve for over 30 years. The workshop covers 13000 square meters and own more than 50 advanced CNC machines. Our engineers & production team will make sure your order delivers with high-quality and fastest time. We also care about valve shipping. The valves will wrap by bubble pouches or paper to ensure the paint will not be damaged. We also fixed valve by plywood stick after we put valve into the box. The plywood case will be painted with necessary marking to make sure the valve will not be damaged during shipping.
