Butterfly Valves

Butterfly Valves are commonly used in applications that require isolation or flow control of liquids, gases and even some solid particles as part of a pipeline. These Industries can include Petroleum, Oil & Gas, Water, Wastewater, Chemical, Power, HVAC & Pharmaceutical. Allowing for a quick shut off, these types of butterfly valves are now commonly being used in place or as an alternative to Ball Valves. This is due to the generally lower cost, weight and installation difficulties that can come with larger sized Ball style with Butterfly requiring less space and support in the pipeline.

Lugged Type High Performance - Double Offset

Lug-style valves have threaded inserts at both sides of the body that allow them to be installed with only bolts and no nuts. The valve is placed between two flanges, one on each side. This setup permits either piece of piping disconnected without affecting the complete process. Due to the double offset movement, the rotation of the disc is eccentric over the seat. The rotational circular movement of the disc turns into an elliptical movement. So, the disc achieves just a few degrees contact with the seat before the valve is fully closed. The Colossus is one of our most reliable products because it's made from high-quality materials that can withstand the harshest conditions while still working reliably over long periods of time with minimal maintenance required.

Less Space In The Pipeline

Less space, results in less material, bringing significantly lower costs in the process. As part of Isolation applications, our valves can be fully open or fully closed with quarter turn movement (90 Degrees) of the functioning lever or actuator. When closed, the reliable seal and disc can provide 100% leak tight downstream shutoff and low-pressure loss across the valve when opened through a streamlined, energy saving metallic disc. These types of valves can also be used to regulate flow pressure or temperature through a multi-position lockable lever or 4-20mA 3-15 psi control.

Main Components

The main components consist of the Body, Shaft, Disc, Elastic Ring (Seat/Seal) O-Ring, Circlip, Washer & Mounting Flange. All of which are available in different materials and specifications to suit your application requirements including Ductile/Cast Iron, Stainless Steel, Duplex, Aluminium Bronze, Carbon Steel & Super Duplex. Depending on application requirements, these valves are also available in a number of body designs including Wafer, Lugged, Flanged, Double Flanged, Triple Offset, Grooved End and High Performance.

Frequently Asked Questions

Depednding on the butterfly valve type valves can require gaskets to create a tight seal and prevent leaks in the system. Gaskets are not requried for rubber lined butterfly valves as the rubber provides this function.

Butterfly valves act as a rotating disc within the valve body and pipeline to control the flow of fluid or gas. This simple yet efficient design allows for quick on/off functionality and precise flow modulation.

Butterfly valves are typically installed by bolting them between two pipe flanges. Proper alignment and torque are essential during installation to ensure leak-free operation. Guide lugs assist with installation as well as threaded fully lugged designs.

Butterfly Valves are used to control fluids, including water, air, gases, and corrosive chemicals. Their wide range of applications suit industries including HVAC, Water Treatamnet, Food & Beverage, Chemical or Oil & Gas.

A double-offset butterfly valve features two distinct offsets in the design to reduce wear and improve sealing performance. Double offset butterfly valves are ideal for high-pressure and high-temperature applications. Redcued actuation cost is provided by lower torque values.

A triple-offset butterfly valve incorporates three offsets to further minimize leakage, making it suitable for critical applications where tight shut-off is essential, such as in the oil and gas industry. Torque and actuation costs are again reduced.

Butterfly valves are an excellent for flow regulation due to their ability to precisely modulate flow rates and medium. They provide efficient control in systems where throttling is required. 4-20mA positioners can be added to build assemblies.

Yes, butterfly valves are suitable for throttling. The degree at which they are throttled should be within the manufacturers specified limits to prevent excessive wear and maintain performance and sealing abilities. 

Butterfly valves usually have a flow direction which will be indicated by an arrow on the valve body. Correct installation ensures optimal performance and prevents flow reversal issues. Bi-directional valves are also available without arrow markings.

Advantages of butterfly valves include a  compact design, lightweight construction, and cost-effectiveness compared to ball valves and gate valves. They also require minimal maintenance and offer reliable shut off performance.

When comparing butterfly valves to gate valves, factors for considerations can be application, cost, and space / weight constraints. Butterfly valves excel in applications where space-saving and efficient flow control are crucial.

The lifespan of butterfly valves varies depending on factors such as material compatibilty, usage conditions, and proper maintenance schedules. Follwoing manufacturers O&M manuals valves and seals can last for many years.
