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 ends.
• Lever operated
• Valves can be offered with electrical and Pneumatic actuators on request.
• END CONNECTION:
  • Screwed ends/ Socket Weld.
  WORKING PRESSURE:
  • Maximum working pressure 69 Bar @ 38° C
  TEMPERATURE LIMITS:
  • Maximum working temperature 175°C

INTRODUCTION
Leader Butterfly Valves are designed to meet the flow control requirement of plumbing, fire-fighting and HVAC application. The body seat is vulcanised in-situ onto the body and offers 100% bi-directional sealing. The lugged wafer-style body has universal design to fit between flanges of all almost all standards.

• Design Standard: BS 5155, EN 593, API 609 CAT. A.
• Lugged Wafer type design makes it compact and take lesser space.
• Dynamic sealing of concentric disc is obtained with vulcanised rubber seat at very low torque.
• High-precision disc external profile for smooth operation & tight shut off sealing with low operating torque.
• Moulded rubber body seat extending onto the contact faces ensures perfect sealing and eliminates the need for separate flange gaskets.
• Notch plate ensures the locking of the hand lever at different positions in addition to open and closed positions.
• Shaft sealing is ensured by double sealing of Bush and ’0’ ring combination.
• Body castings made of superior FG 260 grade cast iron to ensure additional strength.
• Valve disc made of SS304 offers high strength against pressure.
• Shaft made of martensitic stainless steel to ensure maximum strength and torsional rigidity.
• Two-piece stem design which is precisely guided between the PTFE bush & Rubber ‘0’ Rings to prevent leakage, corrosion, and stem seizure.
• Taper disc holder pins to ensure shockproof shaft to disc connection & suitability of replacement at field.
• Easy visual control of open/closed position marked on the notch plate.
• Operation mode manual, gear, electric, pneumatic.
• Available with locking arrangement on request.
• Temper Switch / supervisory limit switches option available on request.
• Top flange as per ISO 5211 to suit F Series flanges of Gears and Actuators.

END CONNECTION

• Suitable for Clamping between flanges as per ASME B16.1 Class-125, ASME B16.5 Class-150, IS 6392, Table 17, IS 1538, BSEN 1092 PN25, BS:10 Table D, E, F, H.

UTILISATION & SERVICE

• Best suited for water, HVAC, fire-fighting service.

WORKING PRESSURE & TEMPERATURE LIMITS

• Maximum Working Pressure: 16 Bar.
• Maximum Working Temperature: 120°C.
