Principle Features
INTRODUCTION
Leader Ball Valves are available in three-piece construction. It offers full flow with minimum turbulence and can balance or throttle fluids. Ball move from closed to full open in a quarter of a turn of the shaft and therefore referred to as quarter-turn ball valve.
- Design St& BSEN ISO 17292.
- Pressure Temperature Rating as per ISO 5208/ API 598.
- Sturdy design for high-pressure & temperature service.
- Three-piece constructions designed for easy online service.
- Floating Ball. line pressure forces the floating ball against the downstream seat to effect bubble-fig. sealing.
- Mirror-finished Solid Stainless Steel Ball ensures bubble-tight sealing and lower operating torques.
- Premium quality PTFE sea. to ensure bubble-tight sealing and lower operating torques.
- Inbuilt antistatic mechanisms to pro.de electrical continuity.
- Blowout-proof stem design.
- Fire-safe design as per API 607, features secondary metal seats act In the event of a fire. after the soft seat totally deform, the Pall moves and touches the metal seat to form a leak. tight seal.
- Screwed Female Tapper ends as per ASME B1.20.1 (NPT) / BS 21 Screwed Female Parallel ends as per ISO 228 / BS 21 available on request.
- Socket-weld / Buff Welded are available on request with 100mrt Nipple on both the ends.
- Lever operated.
- Valves can be offered with electrical and Pneumatic actuators on request.
