A pneumatic butterfly valve is one of the most widely used for effective management of water supply and sewage systems. It consists of a metal disc attached to a pneumatic actuator outside the valve. The actuator is supported by a rod and uses pressurized air to adjust the position of the valve. The disc is installed in the center of the pipe, perpendicular to the fluid flow. When the valve is closed, the disc turns to block the flow of air or fluid completely. When the valve is open, the disc rotates one-quarter of a turn to allow fluid to pass through. When it is in motion, the disc resembles butterfly wings, hence the name given to the valve. Below are 6 advantages that come with this type of valve.
Pneumatic actuated valves are much lighter in weight than some of the available options. This means less support is required for proper installation. It contributes towards ease of installation, and helps to keep costs down. Faster and more accurate motion during valve activity is enabled by the lightweight nature of the valves. It is also a plus when it comes to maintenance. It makes it easier to perform routine maintenance, as well as undertake repairs more comfortably and faster.
2. High Efficiency
The valves are relatively small in size and quick in motion. This is because the pneumatic power source enables the valves to open and close swiftly. Valves are also characterized by high precision for valve positioning. This provides effective shut-off as well as efficient flow of fluid with only one-quarter of a turn. The molded-in, resilient seat of the valve provides extremely tight shut-off in various operating conditions. This goes a long way to prevent leakage. It also saves you time and money.
3. Low Maintenance
Pneumatic butterfly valves are amongst the easiest to maintain. This is partly because they have fewer mechanical parts which contribute to a low wear and tear rate. The resilient seat of the valve is mechanically secured, hence it eliminates the need to bond or cement. Pneumatic butterfly valves are also amongst the easiest to clean, which makes maintenance easier to undertake.
The lower wear and tear rate helps to extend the life span of the valves. This makes the pneumatic butterfly valve one of the most durable on the market. It has a high number of leak-free cycles, which gives it a much higher reliability than other valves in the long run.
Pneumatic actuated valves are amongst the least expensive valves available on the market. This makes it easier to complete your installations within a reasonable budget. It also enables faster project turnaround time. The affordable cost, low maintenance and ease of installation combine to make the pneumatic butterfly valve a cost-effective choice in the long run.
Pneumatic actuated valves are a relatively clean technology. The utilization of compressed air to give motion to the valves helps to maintain a clean system. You need not labor over messy clean-ups that occur with other alternatives such as hydraulic actuated valves, which utilize fluid to fuel operations.
