    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.

    Which is better wafer or lugged butterfly valve?

    When selecting any type of valve for a specific application, it is important to consider the size and pressure rating requirements of the system. In general, wafer butterfly valves are used when reduced weight and cost are desired while lugged butterfly valves provide enhanced structural integrity. The primary difference between wafer and lugged butterfly valves is that the lugged design has two sets of bolts attaching each side of the valve body to its companion flanges, whereas a wafer design typically utilizes only one set of bolts affixed on either side.

    Wafer butterfly valves are lighter, lower in cost and easier to install than their lugged counterpart due to their simpler design which requires fewer components (just halves). This makes them ideal when quick installation or replacement times need to be met or if space availability is limited as they can be installed into very tight spaces without having to install additional gaskets/seals. Wafers have been known to cause higher levels of vibration due mainly to their weaker housing compared with lugs which often require extra supports or braces against high pressures.. Additionally, because a wafer relies on just one set of bolts rather than two like an ISO / Lug Butterfly style does there’s an increased risk for leakage at pipe connections if not fastened properly or using suitable grades/types of mounting nuts & washers etc..

    What is a wafer type butterfly valve installed?

    A wafer type butterfly valve is a quarter turn rotary valve that is typically used to control and isolate mediums such as air, gas, steam, water, oil and other liquids. It consists of a circular disc mounted onto a shaft which is in the centre of the body. The disc can rotate 90 degrees from open to closed positions depending on the direction of flow. The wafer style butterfly valve not only acts as an isolation device but also provides some throttling action due to its semi-lunar shape design.

    Wafer type butterfly valves are installed between two flanged pipe fittings by bolting it directly into them using four stud bolts or lag screws in accordance with ANSI/ASME B16.5 standards for pipe flanges and standard pressure ratinigs (ANSI Class 150/300). In order to achieve a leak-proof seal between the mating flanges, two flat gaskets are inserted between them which must be rated for pressures above those expected in operation.
