Principle Features
INTRODUCTION
Leader forged steel Needle (Regulating) valve offers renewable seat by default with rising stem and hand wheel. It blocks the flow of pipeline through the rotation and lifting of hand wheel as well as stem to drive the lift of disc. There is no relative friction between disc and body sealing surface. The Needle (Regulating) valves have the feature of long service life for opening and closing, can be used as a shut-off valve for small size pipeline.
- 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.
