Forged Steel Floating Ball Valve

Naishi forged steel floating ball valves are made to last and work safely under tough conditions. They rely on single-inclined or V-groove resilient seats that keep a dependable seal whether the pressure is low or high. When the pressure is low the contact area is smaller, so the sealing force goes up. As pressure climbs the contact area expands and the seat can handle the extra force without getting damaged. PTFE and other self-lubricating materials cut down friction and help the valve last longer in service.

Here's what stands out:

• Lip-type resilient seats give a tight seal, keep friction low, and make the valve easier to turn.
• The stem sits at the bottom and is blowout-proof, so it stays sealed even if there's a fire.
• Fire-safe and anti-static features are built in, which is especially useful for soft-seated versions.
• A flat-head stem design means the handle clearly shows if the valve is open or closed.
• Locking holes at the fully open and fully closed positions stop anyone from turning it by accident.
• The whole design is compact and light, needs little maintenance, and runs smoothly with low flow resistance and almost no noise.

These valves come in both full-bore and reduced-bore options. They meet API 608, API 6D, BS 5351 and ASME B16.34. You can choose from a wide range of body, bonnet and trim materials to match different working conditions.
