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.
