Product Description

Introduction:

Ductile Iron Valve Disc Vulcanized Rubber Seat Butterfly Valve | Corrosion-Resistant Flow Control

Tianjin Worlds Valve Co., Ltd. – ISO 9001 & WRAS-Certified Industrial Valve Solutions

CBF01-TF01---Operation and Maintenance ManualDOWNLOAD

Main Spare Part Material Quality of Butterfly Valve-CBF01-TF01

Product Features:

1. Vulcanized Rubber-to-Disc Bonding

Permanent chemical fusion between EPDM/NBR elastomer and ductile iron disc prevents seat detachment during thermal cycling (-20°C to 120°C).

Eliminates compression-set failure common in press-fit seats, extending service life to 50,000+ cycles.

2. Optimal Flow Efficiency

Aerodynamic ductile iron disc design reduces pressure drop by 25% vs. traditional valves.

Full port opening minimizes turbulence in high-flow systems.

3. Triple-Layer Corrosion Defense

Body: 300µm fusion-bonded epoxy coating for chlorine/UV resistance.

Disc: Zinc-nickel plating + epoxy topcoat prevents pitting in pH 5-12 environments.

Stem: 316L SS with PTFE bushings.

4. Zero-Maintenance Design

Self-lubricating RPTFE bearings and triple-sealed stem eliminate greasing needs.
