Wafer butterfly valve

Wafer butterfly valves provide the perfect solution for controlling, throttling or shut off of fluids in any application. This type of butterfly valve is lightweight, compact and designed to fit between flanges with two-piece body construction, making it easily interchangeable with other types of valves without extensive rework. The unique design features a double-latched seal which allows very high flow rates and minimal pressure loss while also providing excellent sealing performance. The disc is connected to a stem on one side and can rotate around its axis allowing for precise control over the flow rate. Butterfly valve manufacturers Available in the following sizes: 2inch,3 inch,4 inch,5 inch, 6 inch, 8 inch, butterfly valve and 60 inch butterfly valve. Wafer style butterfly valve are also highly reliable and require minimal maintenance, making them an efficient and cost-effective choice when compared to other types of valves available on the market today. Whether you need to regulate pressure or just shut off fluid flow in your system, investing in a quality wafer butterfly valve is the best long-term solution you can make.

What parameters need to be provided to buy a butterfly valve？

When looking to buy a wafer butterfly valves, there are a few important parameters that you should keep in mind. The first parameter is the size of the valve. Depending on the application, you'll need to specify how big or small it needs to be. This will determine how much flow can pass through it and also affect its weight and ease of installation.

The second important parameter is butterfly valve torque rating, which determines how much pressure it can handle without malfunctioning or becoming damaged. It's typically measured in Newton-metres (Nm) so make sure you know exactly what level of torque your specific application requires before buying.

Thirdly, consider materials used for construction as they determine strength, durability and corrosion resistance of the butterfly valve this makes stainless steel butterfly valve a popular choice since it will last longer under harsher conditions than plastic butterfly valve would endure. Lastly, think about operational temperature ranges when selecting a butterfly valve since extreme temperatures may require specialised materials for maximum performance and longevity.
