Valve Introduction
Floating ball valve features stem-limited design, with medium pressure pressing the ball against the downstream seat for sealing. ISO 5211 direct-mount pad allows actuator installation without bracket. 90°quarter-turn operation for fast switching, full- bore design for low flow resistance. PTFE/PPL soft seats ensure bubble-tight shut-off. Blowout-proof and anti-static stem, self-compensating carbon packing minimizes external leakage, low torque, easy maintenance. Widely used in water, HVAC, gas, industry, environmental protection, and other automated piping systems.
Design Features
1. ISO 5211 mounting pad, integrally cast with the body.
2. Blowout-proof stem design.
3. Anti-static device.
4. Dual stem sealing design to prevent packing leakage.
5. Resilient seat design for low operating torque.
6. Fire-safe structure.
7. Shell by silica sol investment casting, with smooth surface fin
