Introduction:
Unimac Control Systems specialize in manufacturing, supplying and exporting of Industrial Butterfly Valves in India. Butterfly valves are used in a variety of settings. Both slurry and high volume water applications suit them well. Some common uses for butterfly valves include the following: water cooling, air cooling, gas cooling, fire safety, etc. Industrial butterfly valves are a type of quarter-turn valve used to control the flow of fluids in various industrial applications. They're called "butterfly" valves because of the wing-like disc that rotates within the valve body to regulate the flow.
Here are some key features and considerations regarding industrial butterfly valves:
- Quarter-Turn Operation: Butterfly valves operate on a quarter-turn mechanism, meaning they can be fully open or fully closed with a 90-degree rotation of the disc.
- Simple Design: Compared to other types of valves, butterfly valves have a relatively simple design, consisting of a disc, a stem, and a valve body. This simplicity often translates into lower manufacturing costs and easier maintenance.
- Flow Control: The position of the disc within the valve body determines the flow rate. When the disc is parallel to the flow direction, the valve is fully open, allowing for maximum flow. Conversely, when the disc is perpendicular to the flow direction, the valve is fully closed, blocking the flow completely.
- Low Pressure Drop: Butterfly valves typically have a low pressure drop across the valve when fully open, meaning they don't significantly impede the flow of fluids.
- Various Sizes and Materials: Industrial butterfly valves are available in a wide range of sizes, from small sizes used in HVAC systems to large sizes used in industrial pipelines. They're also manufactured in various materials, including stainless steel, carbon steel, cast iron, and PVC, to suit different applications and operating conditions.
- Resilient Sealing: The disc of a butterfly valve can have either a resilient seat or a metal-to-metal seat. Resilient-seated butterfly valves are commonly used for applications where a tight seal is required, while metal-seated butterfly valves are preferred for high-temperature and high-pressure applications.
- Manual and Automated Operation: Butterfly valves can be operated manually using a hand lever or gear operator, or they can be automated using pneumatic, electric, or hydraulic actuators for remote operation and control.
- Lug and Wafer Design: Butterfly valves are available in lug and wafer designs. Wafer-style valves are sandwiched between pipe flanges, while lug-style valves have threaded inserts or lugs on the valve body that allow for easy installation and removal from the pipeline.
- Fire-Safe Design: Some butterfly valves are designed to comply with fire safety standards by incorporating features such as metal seats and graphite packing to prevent leakage in the event of a fire.
- Applications: Industrial butterfly valves find applications in various industries, including oil and gas, chemical processing, water and wastewater treatment, HVAC, power generation, and marine.
When selecting an industrial butterfly valve for a specific application, factors such as the type of fluid being handled, operating pressure and temperature, flow rate, size constraints, and environmental conditions have to be thoroughly thought out in order to guarantee peak performance and dependability.
