Definition of an AWWA Butterfly Valve
AWWA stands for the American Water Works Association. A butterfly valve 
regulates the medium's flow by allowing and restricting fluid flow. In this kind of 
valve, the rod is joined by a disc. This disc allows fluid to pass through the valve.
Lever-operated, hand-wheel-operated, and gear-operated are the three variants 
available for AWWA butterfly valves. These valves come with either an electric or 
pneumatic actuator, depending on your requirements.

What is a Butterfly Valve?
A butterfly valve is a part of the quarter-turn rotary motion valve family (bi- 
directional) that is used to prevent, control, or start flow.
Quarter valves include the type of valves in which 1/4 turn of the disk is enough to 
fully open or fully close the flow. Quarter turn valves are fast to operate as they 
only require 90 degrees of rotation in order to move from the fully open to the 
fully closed position. This is also why they are also called fast-acting valves.
The butterfly valve gets its name from the shape of the plug and how it moves.
The plug is disc-shaped with a rod passing through it which makes it look like a 
butterfly. When the rod is turned, it rotates the disc by a quarter such that the disc 
falls perpendicular to the flow and stops it. And to restore the flow, the rod 
rotates the disc back to the original position, i.e. away from the flow. The valve 
can also be opened in stages to control the flow.
Advantages of Butterfly Valve:
A high-pressure rebound follows the low-pressure decrease.
Can be installed/removed easily without disrupting the piping system
Costs less because there is less raw material.
Design is small & requires little room.
Durable
Easy to install and operate
Energy efficiency has improved.
Good for on/off and throttling
Good for slurries
Large seating area
Larger sizes are available.
Less assistance is required.
Lightweight
Low operation torque allows for simple operation.
Low-pressure drop.
Maintenance is easier, inexpensive and less required.
No gas pockets
Numerous actuation methods are available.
Piping system easily supports the weight.
Quick operation; little time spent opening or closing.
Quite accurate.
Various seat and disc materials are available.

Pneumatic Actuated Butterfly Valve manufacturer in USA
SVR Global is a prominent Pneumatic Actuated Butterfly Valve manufacturer in 
USA that provides a variety of pneumatically operated valves. We test each of 
our pneumatically operated valves to make sure it meets the needs of our 
customers.
Additionally, we provide custom-built pneumatic actuators that are manufactured 
to meet particular industrial requirements.
Definition of a Pneumatic Actuated Butterfly Valve:
Pneumatic actuated butterfly valves are quarter-turn rotational valves used to 
prevent, control, or start the flow of medium through systems. These valves are 
ideal for managing vast quantities of fluid or gases at low pressure.
A pneumatic actuated butterfly valve converts compressed gas energy into 
mechanical motion. A pneumatic actuated butterfly valve uses pressurized air or 
gas to convert energy into linear or rotational motion. They are very efficient, 
cost- effective, and safe. They are especially used to open and shut the valve. They 
look like a huge circle. This valve is used to control or isolate fluid flow.
Working of Pneumatic Actuated Butterfly Valve:
A butterfly valve should ideally have a disc in the middle of a stem and pipe. The 
stem is attached to an actuator (for automatically actuated valves) or a handle (for 
manually operated valves). The valve's stem is attached to a pneumatic actuator, 
which uses pressurized air to move a piston or a diaphragm to either close or open 
the valve.
When the valve is closed, the disc is held firmly by a valve seat and rests 
perpendicular to the fluid flow. The stem is sealed with an O-ring to avoid leaks 
and provide a snug but flexible fit. The disc moves to a position parallel to the 
fluid flow when the pneumatic actuator rotates the stem at a 90-degree angle. The 
flow becomes proportionate or throttled when the stem is partially rotated, and the 
valve can be used to modulate services.
Pneumatic Actuated Butterfly Valve is used in industries like:
Chemical industry
Mining industry
Petroleum industry
Types of Pneumatic Actuated Butterfly Valve:
Wafer-style butterfly valve
Lug-style butterfly valve

Concentric Butterfly Valve Manufacturer in USA
SVR Global is a reputable Concentric Butterfly Valve Manufacturer in USA with 
a wide variety of Concentric Butterfly Valves. Our products have been well 
received for many years by various prestigious organizations.
What is a Concentric Butterfly Valve?
The most typical kind of butterfly valve is a centric or concentric valve, commonly 
referred to as a zero-offset butterfly valve.
The disc is in the center of the valve body, and the stem is in the middle of the 
disc. The disc remains in the passage, but due to its thinness, it offers very little 
flow resistance. Some disc sections are always in contact or rubbing against the 
seat as it opens or closes. This configuration results in friction being applied to the 
seat each time the valve is used.
Concentric butterfly valves are also referred to as resilient seated butterfly valves 
since it depends on the flexibility of the seat rubber when the flow is closed, for 
the reliability of the seal.
