Replace the Butterfly Valve Regularly to Make Sure Its Efficiency

Butterfly valves are designed to turn on and off or to reduce liquid flow through piping system. A disc is installed on a rod and turning the valve in one way, it will block the flow and while turning it another position, flow is allowed.

The butterfly valve replacement period have some simple and consistent traits. The design of Butterfly Valve is inherently simple and economic in that it has fewer components than other valves. And on account of this, it is relatively easier to repair and maintain, cheaper to produce and install. And the time needed to install butterfly valves is less attribute to its less-complicated structure. To shut off the piping system, butterfly valves can provide a quicker way; it can achieve complete shutoff easily and modulate flow as well. These advantages make butterfly valves widely used in many different applications to stop or modify the flow of fluid. Actuation of fluid flow can be manual by handle, pneumatic actuators operator and can also be automotive through equipment. Automated actuators have different types, such as electric, pneumatic and hydraulic. These three different types of actuator has different characteristic each and it is according to the requirement of the system to control the valve, speed for automatic actuator. Pneumatic valves can be automatic and semi type.

Different kinds of butterfly valves have different failure rate. The failure rates are calculated to figure out the useful lifetime of a butterfly valve. You can know how long the produce can perform properly according to its lifetime. And one beyond its useful lifetime, failure rate will begin to increase. In order to keep failure rate in a fixed figure, it is necessary to replace the butterfly valve at regular interval.

Then how often should you replace the pneumatic actuators replacement period? Why should you change it? There are several tips for you to follow. When you find that the butterfly valve begin to clogged and the flow cannot be control fully, or if the results are poor idling, acceleration start to slow down and other similar ailments, it is revealed that it is time to replace butterfly valve. There is no fixed standard on how long should a butterfly valve be replace, but if the above ailments shows, you should think about replacing it.

Generally speaking, the device should be test and replace every two years. Temperature and pressure of the working environment is very important for the butterfly valve to operate safely and once the valve fails, it will cause damage to the device and impact the efficiency. Based on working condition of the valve, it is suggested by some professionals that test and replace pneumatic actuators every two years. To test the temperature and pressure, the lever need to be lifted to check whether there is any water sprays from it, if no water sprays; it is time to replace one. One thing to notice that whey you test the valve there may cause debris inside the pipe and lead to clog, it would be better to test on valve that is leaking.
