Butterfly Valves – A Complete Guide by Engimek
At Engimek, we take pride in delivering world-class valve solutions that serve industries across the globe. Among the many industrial valves, butterfly valves from Engimek solution stand out due to their simple yet highly effective design. This article dives deep into their functions, specifications, applications, pros and cons, market trends, and why Engimek is your trusted partner for butterfly valve solutions.
What are Butterfly Valves?
A butterfly valve is a quarter-turn valve that uses a disc to regulate the flow of fluids. Think of it as a gate that can swing open or close to allow or block flow. The disc rotates around an axis, moving between 0° (fully closed) and 90° (fully open). This straightforward design makes butterfly valves compact, cost-effective, and easy to operate.
Main Functions of Butterfly Valves
- Regulating flow: Control the flow of liquids, gases, or steam with precision.
- On/Off service: Perfect for quick shut-off and opening applications.
- Minimal pressure drop: Ensures fluid passes smoothly when fully open.
- Tight sealing: Prevents leakage when in a closed position.
