描述
气动软密封蝶阀
This pneumatic soft-seated butterfly valve consists of a rubber-seated valve
body with a carbon steel or stainless steel butterfly disc and valve shaft. It
is designed for flow regulation and shut-off in water, wastewater, air, gas,
steam, oil and mildly corrosive fluid pipelines.
The valve is widely used in food processing, pharmaceutical, chemical,
petroleum, power generation, textile, paper and general industrial systems.
Its compact construction, quick quarter-turn operation and replaceable sealing
components provide reliable bidirectional sealing and convenient maintenance.
主要特点
- Compact and lightweight butterfly valve design.
- Fast opening and closing with low operating torque.
- Suitable for installation in any position.
- Replaceable sealing components for easy maintenance.
- 在适当条件下，可实现可靠的双向密封，且无可见泄漏。
- Ageing-resistant and corrosion-resistant sealing materials.
- Available with double-acting or spring-return pneumatic actuators.
- Optional manual override, solenoid valve, limit switch and positioner.
- ISO 5211 mounting interface for convenient actuator installation and replacement.
