SPV Valve’s factory uses advanced processing machinery to produce valves that adapt to your specifications. Passing through quality testing in every stage, our butterfly valve varieties have earned API 609, API 607, API 6FA, API 598, SIL3, CE, ISO 15848-1, and GOST certification. As such, they work well for chemical, food, and pharmaceutical applications.
High-performance butterfly valves are also called double offset or double eccentric butterfly valves. Along with their ability to withstand liquids and gases, our high-performance butterfly control valves are also made with a fireproof structure. Adding stops on our valves improves their efficiency in controlling fluid flow and preventing over-travel. Each valve is also made with a two-way pressure Class 150-900 and adjustable packing glands to ensure zero external leakages.
Made for general service, our valves are custom-made, with precise sizes, to fit your requirements and prevent problems during their application. SPV Valve provides strong adjustment and installation solutions to make setting up our valves easier for any location.
Butterfly Valves
Efficient sealing makes our valves more convenient to open and close, along with enhancing their overall performance.
A low fugitive emissions design and high temperature resistance makes our valves more fit for extreme cycling applications.
Used in low pressure applications, our concentric valves come with flexible seat rubbers for easier flow control.
Made easy to install due to the wide range of different sizes, wafer-style butterfly valves come with multiple centering holes and open and close quickly during pneumatic actuation.
Providing a safe alternative to most valves, lug-style valves contain threaded bolts all around and can be applied as the end-of-line service.
SPV excels in producing custom-made flange butterfly valves desired by your industry for optimum performance and longer periods of service.
Applied in extreme pressure environments, this valve type comes with metal seating that resists cracking and degeneration caused by high temperatures.

Industrial Butterfly Valves101
A butterfly valve is a machine tool that regulates, restricts, or stops the pressure and flow of gases, liquids, or slurries through a piping system. The valve system operations occur through the opening, closing, or partly blocking different pathways.
This mechanical equipment is used in several industries, including oil and gas, water treatment, and more. Let’s find out more about the significance of butterfly valves in many industrial applications and why they are widely used compared to other valve types.

Why Use a Double Offset Butterfly Valve?
A butterfly valve is used to regulate both liquid and gas flow through pipes. It is a type of quarter-turn motion valve that can open and close whenever the rotating disc is turned at ninety degrees. Moreover, a butterfly valve is used in several industries due to its compatibility, reliability, and low maintenance features.
In fact, there is a substantial reliance rate on the butterfly valve industry because of its extensive utilization in different applications. This includes the automation, wastewater treatment, petrochemical, chemical, food and beverage, and pharmaceutical segments.
Industrial Butterfly Valves101
Basically, butterfly valves consist of four main parts: body, disc, stem, and seat. Each segment has a vital function.
Body
Butterfly valves have bodies that can fit between two pipe flanges and the most common body structures are wafer and lug. The lug’s body has protruding lugs that present bolt holes matching those in the pipe flange. On the other hand, a wafer’s body does not contain protruding lugs. Instead, the wafer is sandwiched between pipe flanges, then the flange bolts surround its body.
Stem
The stem part could be a one-piece or two-piece shaft structure. It is protected from the media in most resilient seated designs, allowing an efficient material selection concerning cost and mechanical properties. On the contrary, the stem is in contact with the media in high-performance butterfly valve designs.
Disc
The disc is a moveable part that allows and restricts flow through the valve, rotating in one quarter-turn or ninety degrees. Thus, it is the flow closure in a butterfly valve, the counterpart of a plug when it comes to a plug valve, a ball in a ball valve, or a gate in a gate valve.
Seat
The seat is a surface inside the body that comes into contact with the disc to provide a tight shutoff. It can be a fireproof seat, resilient seat, or metal seat used to prevent compressed fluids or combustion gasses from getting into the manifold.
Butterfly Valves Advantages & Disadvantage
Like other types of valves, butterfly valves have their benefits and downsides.
Advantages
Butterfly valves are lightweight and only require smaller space compared to other industrial valves in the business. Due to its compatibility, it is manageable and only needs a ninety-degree rotation of the handle to support a full opening or closing of the valve. Also, even if it is high-performing, it is easy to maintain and very cost-efficient.
Disadvantages
Butterfly valves’ disc part tends to face the flow even if it is fully opened, leading to a pressure switch over the valve. Also, choked flow and possible cavitation are a worry when butterfly valves perform. Moreover, there are instances that they have a poor sealing function, and throttling is restricted to low-pressure drop applications.
What are butterfly valves used for?
Like other types of valves, butterfly valves have their benefits and downsides.
Oil and Gas industry
High performing butterfly valves are widely used in the oil and gas industry due to their capability to deliver a high degree of durability and reliability to ensure long service and low maintenance needs of pipelines in oil and gas applications.
Water Butterfly Valves
Butterfly valves are also used in water supply, collection, distribution, and pumping stations because of their capacity to restrict and isolate the flow of fluids. These applications usually make use only of double offset and triple offset butterfly valves.
Cryogenic Butterfly Valves
Generally, cryogenic butterfly valves are used on processes concerning liquefied gases like oxygen, liquid nitrogen, and liquefied natural gas (LNG). They can also be used in fuel gas supply systems (FGSS) and LNG engines or gas turbines.
Types of Butterfly Valves
There are three main types of butterfly valves. First is the rubber-lined valve, which are less expensive compared to other types. Then there’s plastic-lined valves are used for sanitary and abrasive applications. On the other hand, the metal types are utilized for high-pressure and high-temperature applications.
Butterfly Valves by Body Types
Here are the different butterfly valves segmented by body types.
Wafer
A wafer style butterfly valve features two or more centering holes to support installation between pipes. They are widely used since they are lighter and cheaper.
Lug
A lug style features threaded metal bolts around the entire body. Its main application is to connect and disconnect piping systems – from one side without distributing on the other side of the system. A lug style can replace a wafer valve. However, you can’t switch from a lug to a wafer.
Flanged
Flange butterfly valves are known for their large sizes. They are used for various methods of piping connection. These types have raised or winged edges in the enclosure so that they can be fastened in between two pipes.
Welded
The welded butterfly valve is used for very high-pressure operations. Since most plastic-lined valves are very limited to PN10/16 (150#) flanges, the welded butterfly valve is rarely seen with plastic-lined valves. So, this type is typically made from stainless steel, aluminum, or bronze elements.
