Types of butterfly valves

Check Valves Ready For Shipment. Multiple Models In Stock. Over 30Valves Ready To Ship. What are the different types of butterfly valves? When to use a butterfly valve or ball valve?

Can butterfly valves be used for flow control or throttling?

What is the difference between a lug type butterfly valve and wafer? There are main categories of butterfly valves: Rubber-lined , Plastic-lined , and Metal. Less expensive valves for non-demanding, non-abrasive, lower temperature applications. The two manual methods are handles and gear wheels.

Automated actuation is also possible, depending on the model! Buttwelded end connection also available upon request. The wafer body is placed between pipe flanges,.

The lug body has protruding lugs in the periphery.

Lug Style Butterfly Valve. Flanged Butterfly Valve. In this types, the body has flanged that match with pipe flange dimension. The eccentric type can be single, double, or triple-offset type.

The most accessible in the business sector for eccentric type are double-offset or triple-offset. A few times this sub-sort of butterfly valve is additionally called as an elite butterfly valve. BUTTERFLY VALVE DESIGN CONCENTRIC BUTTERFLY VALVE (CENTRIC) The concentric butterfly valve is used in water.

DOUBLE ECCENTRIC BUTTERFLY VALVE. Double eccentric butterfly valves find large application in. TRIPLE ECCENTRIC BUTTERFLY VALVE. Triple offset butterfly valves are built with high-grade. Another important feature is that these valves can be equipped with a gearbox-like mechanism.

In the setup, the hand wheel from the gears is connected to the stem, making the valve easy to operate but at low speeds and for larger valves. With that in min let’s look at ways to install different types of butterfly valves. Types Concentric butterfly valves – this type of valve has a resilient rubber seat with a metal disc.

Doubly-eccentric butterfly valves (high-performance butterfly valves or double-offset butterfly valves ). Triply-eccentric butterfly valves (triple-offset butterfly valves ) – the seats are either.

In the above chart, you can see the types of valves and their function. Isolation valve isolates or cuts the supply of fluid when needed. A control valve that regulates the flow of fluid falls in the regulation category.

A different installation procedure is used for each one. Wafer style is the more common of the two and is less expensive than. Butterfly Valves are typically used to open and close (seal type ) or adjust the medium flow in pipes.

A typical flanged butterfly valve is illustrated in Fig. They are usually manufactured in flange wafer, and lug, or single-flange- type designs. Resilient Seated Butterfly Valve(RSBFV) There are two basic designs: Cartridge Seated utilizes a rubber seat over a hard backup ring, usually phenolic, making the seat very rigid. Installation requires only inserting the valve body between flanges, centering it, and tightening the bolts to specified torque. Bundor offers a full line of butterfly valve including lever operated butterfly valve,worm gear operated butterfly valve,flanged butterfly valve,PTFE lined butterfly valve and metal seal butterfly valve.

Butterfly valves engineered by Bray including resilient seated butterfly valves , double offset high performance butterfly valves , triple offset premier isolation butterfly valves and high performance valves for the sugar industry. After years of development, we have extensive experience in the production and processing of soft seal butterfly valves. Pinch valves offer many benefits over the other types of valves. They can be used for handling corrosive fluids as there is no contact between the fluid carried and the actual valve mechanism.

Once suitable sleeve material is selecte this valve can work with a variety of fluids.
