Principle Features
INTRODUCTION
Leader Ductile Iron Sluice Valves (Non-Rising Spindle) are best suited for services that require infrequent valve operation, and where the wedge is kept either fully opened or fully closed. It offers the ultimate dependable service wherever minimum pressure drop is important.
- Designed as per 1S:14846.
- Bolted Bonnet, Inside screw, Non-Rising Stem.
- Solid Wedge, Metal to Metal seating.
- Body & Bonnet castings made of superior Ductile Iron ASTM A395 grade to ensure additional strength.
- Gun Metal Body & Wedge rings, Stainless Steel Stem.
- Compact & rigid structure.
- Provided full flow with minimal pressure drop.
- Small opening and closing torque.
- Using Non-Asbestos packing, reliable sealing, light and flexible operation.
- Robust construction of hand wheel in open spoke design.
- Provision for re-packing under pressure in the installed condition.
- Easy visual control of open/closed position marked on the hand wheel.
- Operation mode manual, gear, electric, pneumatic.
- Available with open-shut indicator & locking arrangement on request.
- Flanged ends as per ASME B 16.5 CL-150 (FF).
- Widely used in water distribution, power plants and pipeline for access or cut off the medium pipeline opening and closing devices.
END CONNECTION
- Flanges as per ASME B 16.5 CL-150 (FF), Drilled.
- Flange drilling as per other standards also available upon request.
