Cast Iron Rubber-Lined Butterfly Valve

Description

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.

Technical Specifications:

• Pressure Class: PN10 / PN16
• Size Range: DN50 – DN1200
• Applicable Medium: Water, sewage, seawater, weak acids and alkalis
• Operating Temperature: -10°C to 80°C

Main Parts and Materials:

Key Product Features:

1. Full Lining: Elastomer liner covers the entire wetted body surface for corrosion resistance.
2. Bubble-Tight: Zero leakage in both directions.
3. Low Torque: Centerline design with self-lubricating bushings for easy operation.
4. Light Weight: Much lighter than an equivalent gate valve.
5. Actuation Options: Handle, worm gear, electric or pneumatic.

Applications:

Ideal for Water Supply, Wastewater Treatment, Desalination, and Chemical Dosing Lines. Specifically suited for corrosive or abrasive media where an unlined iron body would degrade.
