描述

The Cast Iron Rubber Lined Butterfly Valve is a flanged centerline butterfly valve whose body is fully lined with elastomer. The disc rotates within the liner to provide tight, bidirectional shut-off, while the lining protects the iron body from corrosion and abrasion. It is a versatile, low-maintenance valve for water and mildly corrosive media.

技术规格:
  • 压力等级: PN10 / PN16
  • 尺寸范围: DN50 – DN1200
  • 适用介质: Water, sewage, seawater, weak acids and alkalis
  • 工作温度: -10°C to 80°C
Main Parts and Materials:
部件名称材料
阀体铸铁HT200 / 球墨铸铁QT450
阀瓣Ductile Iron (rubber-coated or nickel-plated)
衬里EPDM / NBR
阀轴不锈钢2Cr13
操作装置Worm Gear / Lever
产品主要特点:
  1. Full Lining: Elastomer liner covers the entire wetted body surface for corrosion resistance.
  2. Bubble-Tight: 双向零泄漏。
  3. 扭矩小: Centerline design with self-lubricating bushings for easy operation.
  4. Light Weight: Much lighter than an equivalent gate valve.
  5. 驱动选项: Handle, worm gear, electric or pneumatic.
应用:

适用于 供水, Wastewater Treatment, Desalination以及 Chemical Dosing Lines. Specifically suited for corrosive or abrasive media where an unlined iron body would degrade.
