Naishi floating ball valves are designed for durability, safety, and optimal performance. Utilizing single-inclined or V-groove resilient seat structures, the valves ensure reliable sealing across a wide range of pressures. At low pressure, reduced contact area generates high sealing pressure; at higher pressures, increased contact area allows the seat to absorb greater thrust without damage. PTFE and other self-lubricating materials minimize friction, extending service life.
Key Features:
● Sealing Efficiency – Lip-type resilient seats ensure tight sealing, low friction, and reduced operating torque.
● Stem Safety – Bottom-mounted, blowout-proof stem maintains sealing integrity under fire conditions.
● Fire and Static Safety – Equipped with fire-safe and anti-static designs, ideal for soft-seated applications.
● Position Accuracy – Flat-head stem design ensures handle position accurately indicates valve status.
● Locking Mechanism – Locking holes at full-open and full-closed positions prevent unintended operation.
● Design Benefits – Compact, lightweight, and low-maintenance; offers smooth operation with minimal flow resistance and noise.
Naishi floating ball valves are available in full bore and reduced bore types. They conform to API 608, API 6D, BS 5351, and ASME B16.34 standards. A wide range of body, bonnet, and trim materials is offered to suit diverse service conditions.
