Butterfly Valves

Butterfly valves are low profile, on and off flow control plumbing valves. This valve type features an internal disc, or wing, that opens and closes 90 degrees about a center axis. The butterfly valve is engineered to remain locked in position as it is opened or closed along its range of motion. This unique design allows plumbing flow to be started, stopped or restricted as needed for regulating the delivery of liquids or gases in pipe systems. The increased ability of butterfly valves to control flow makes them ideal choices for pipelines that often experience needs in repair, maintenance cleaning, or changes to plumbing orientation. Butterfly valves are highly effective in industrial applications due to their durability, corrosion resistance, functional ease of use and range of operation. This valve type is frequently chosen for use in chemical handling and processing, in manufacturing plants, water purification, industrial wastewater control, irrigation, food lines, high pressure scenarios, swimming pools, aquatics, aquariums and space restricted applications.

Butterfly valves are available in three main styles: lever handle, gear operated and lug. Butterfly valves come with either a grip-button lever or gear reduction turn handle that is used for valve operation and actuation. Levered butterfly valves are also known as quarter turn valves and have been engineered to fully open and close with only a 90 degree (i.e. quarter) turn of the lever. The lever type butterfly valve features an easy to use grip-button handle that stays in place when released and are best suited for smaller diameter piping and low stress applications. Geared butterfly valves feature a spigot type turn handle with internal gears that work together to open or close the valve disc. Gear butterfly valves are best suited for medium to large diameter pipe and high stress scenarios. Lug butterfly valves feature dedicated bolt attachment / lug locations. These allow one side of the valve to remain attached and the other disconnected for making pipeline maintenance, repair or adjustments. Lug type butterfly valves also come in actuator ready models without a lever or handle to prime them for installation with an actuator.

In butterfly valves, we provide some of the industry’s best brands, offering Hayward butterfly valves as well as Red Flag and Georg Fischer butterfly valves. The valves are available in sizes from 2” up to 12”. Non-standard sizes up to 24" are available on request. Our butterfly vavles are manufactured from high strength, corrosion resistant thermoplastic PVC or CPVC rated for up to 150 PSI (10.3 bar) @ 70 ˚F (21 ˚C). Polypropylene and PVDF butterfly valves can be provided on request. Butterfly valve disc materials are either PVC, CPVC or PP (polypropylene) with valve seats offered in EPDM, Viton or Nitrile. Valve stems are made from 316 stainless steel. The materials used in butterfly valve production are approved per NSF / ANSI 61 and 51 standards that certify them for potable water use and as lead free plumbing. Butterfly valve are installed using flange or stud pack type connections. Many of our butterfly valves come with 2 year manufacturer warranties.

Butterfly valves are low profile, on-off flow control pipe valves designed to regulate liquids, chemicals, and other fluids. An internal disc rotates 90 degrees around a central axis that provides precise flow control with the ability to lock at multiple positions. Their design allows for quick starting, stopping, or restricting media flow. This adaptability makes butterfly valves ideal for pipelines that demand operating flexibility, frequent valve cycling, or that require frequent repair, maintenance, or changes in plumbing direction. From industrial plumbing and manufacturing to chemical processing and water treatment, butterfly valves are trusted for their ease of use and streamlined performance.

Key Features

Industrial butterfly valves offer several advantages for demanding work environments. These valves are known for their durability, high corrosion resistance, and ease of use. CPVC and PVC butterfly valves provide exceptional chemical resistance and are well suited for chemical handling and water treatment plants. Professional butterfly valves are engineered for reliability and operational efficiency in challenging conditions. The compact, lightweight design saves space and simplifies installation compared to bulkier valve types.

Butterfly Valve Types

PVC Pipe Supplies provides three main types of industrial butterfly valves, each engineered for specific performance and installation needs:

Lever Handle Butterfly Valves

Lever handle butterfly valves feature a thin body design and an internal disc for flow control. The ergonomic grip lever locks in place and allows for quick on/off operation with a full 90 degree range of motion. Most models offer multiple stop positions for throttling. Lever valves are ideal for small to medium pipe diameters and are easy to install and operate. They are recommended for systems dealing with aggressive, corrosive chemicals, abrasive media, or applications that require reliable flow regulation. They are widely used in water treatment, chemical handling, and other industrial and process systems.

Gear Operated Butterfly Valves

Gear operated butterfly valves are equipped with a heavy duty gear and spigot style handle system. The built-in gearing mechanism allows for precise flow control and makes operation effortless, even on larger diameter pipes and high stress environments. Geared butterfly valves are suitable for demanding industrial installations where throttling, isolation, and superior durability are required.

Lug Butterfly Valves

Lug butterfly valves are built with additional bolt and lug ports around the body to provide tight flange connections and easy disassembly for maintenance, cleaning, or repair. The lug design allows either side of the adjacent piping to be disconnected without affecting the other. Lugged butterfly valves are available in levered, geared, and actuator ready models to suit manual or automated flow control setups. Commonly used in water treatment, aquatics, chemical processing, marine applications, and manufacturing.

Common Butterfly Valve Applications

Our professional butterfly valves are trusted across many applications, including:

Chemical handling and processing
Manufacturing plants
Fire protection systems
Water purification and treatment
Industrial wastewater control
Agriculture irrigation systems
Mining and slurry operations
Food and beverage lines
HVAC systems
Swimming pools, aquatics, aquariums, and other space restricted work environments

PVC and CPVC butterfly valves are used in various chemical applications due to their resistance to harsh substances and their suitability for both indoor and outdoor use.

Butterfly Valve Sizes and Options

PVC Pipe Supplies partners with leading brands such as Hayward, Red Flag, and Georg Fischer to provide a full supply of industrial butterfly valves. Our valves are available in sizes from 2” to 12”, with custom sizes up to 24" available on request. Constructed from high strength, corrosion resistant thermoplastic PVC or CPVC. We also offer options in polypropylene and PVDF for specialized needs. Disc materials include PVC, CPVC, or PP (polypropylene), with seat materials offered in EPDM, Viton, or Nitrile, and all stems are crafted from 316 stainless steel.

Certifications

All butterfly valves meet NSF/ANSI 61 and 51 certifications for potable water and lead free plumbing use. Installation is simple with flange or stud pack connections available. Many models include a 2 year manufacturer’s warranty for manufacturing defects.
