Description
1. Overview of Electric Soft-Seal Butterfly Valve
VTON electric soft-seal butterfly valves integrate rubber-sealed butterfly mechanisms with electric actuators, allowing precise control of fluid flow with input signals (4-20mA or 1-5VDC) and single-phase power. These valves are lightweight, compact, and highly efficient, making them suitable for automatic control systems across industries.
Applications:
- Food processing
- Environmental protection
- Petroleum
- Papermaking
- Chemical industry
- Teaching and research
- Power generation
2. Features
- Compact and Lightweight: Easy to install, disassemble, and repair, with installation flexibility.
- Efficient Operation: Low operating torque and quick 90° rotation for rapid opening and closing.
- Linear Flow Characteristics: Provides excellent regulation performance.
- Pin-Free Design: Eliminates potential internal leakage points.
- Replaceable Sealing Element: Reliable bi-directional sealing with replaceable seals.
- Customizable Coatings: Options for nylon or PTFE coatings on the butterfly plate for enhanced performance.
- Soft-Seal Design: Combines metal and elastic non-metallic materials for optimal sealing performance.
