Tianjin Worlds Valve Co., Ltd. offers a 4‑inch (DN100) electric actuated wafer butterfly valve featuring a two-piece shaft design, a CF8M (AISI 316) stainless steel disc, and a replaceable EPDM seat. This valve is engineered for reliable automated on/off and modulating control in water treatment, HVAC, chemical processing, and general industrial applications.
1. Two-Stem Design – Enhanced Structural Integrity
The upper and lower shaft configuration provides exceptional torsional strength, resisting bending and deformation under high pipeline stress or pressure surges.
Ensures precise, stable disc alignment throughout its entire 90-degree rotation, resulting in smooth, low-friction operation and reduced actuator strain.
Minimizes mechanical stress and wear on stem and bearing points, significantly prolonging valve service life and reducing long-term maintenance needs.
2. CF8M Stainless Steel Disc – Superior Corrosion Resistance
CF8M (AISI 316) offers excellent resistance to pitting, chlorides, and general corrosion in water, seawater, and mild chemical environments.
Outperforms standard 304 grades, making it ideal for harsh or marine applications.
Precision-machined disc interacts perfectly with the seat to create a reliable, bubble-tight seal.
3. Replaceable EPDM Seat – Easy Maintenance & Low Lifecycle Cost
The EPDM seat can be replaced in the field without removing the valve from the pipeline, significantly reducing downtime.
Eliminates the need to replace the entire valve when the seat wears — only the seat needs replacement.
EPDM provides bubble‑tight shut‑off (Class VI), excellent resistance to water, steam, ozone, and aging.
Temperature range: -20°C to +120°C.
Alternative seat materials (NBR, Viton, PTFE) available for specialized media.
4. Electric Actuator – Remote & Precise Automated Control
Enables on/off or modulating control from a control room, reducing manual labor and improving response time.
ISO 5211 top flange allows direct actuator mounting without custom brackets.
Integrates with PLC, DCS, or SCADA systems via 4-20mA signals, feedback relays, and communication protocols.
Manual handwheel override for operation during power outages or maintenance.
5. Wafer-Style Body – Compact & Cost-Effective
Installs directly between standard pipeline flanges using through-bolts, saving space, weight, and installation time.
No companion flanges required – lightweight and compact footprint.
Face-to-face dimensions conform to ISO 5752 / EN 558 Series 20.
