 FAQ     

Q: What is the accuracy of this backpressure valve?

A: R71 backpressure valves are highly accurate. Specific accuracy values may vary depending on the use environment and measurement conditions, but generally meet the accuracy requirements of most industrial and laboratory applications.

Q: What scenarios are the 300 psi pressure range suitable for?

A: It is suitable for pressure control in a variety of industrial production processes, such as fluid transportation and pressure regulation in chemical, pharmaceutical, food and beverage industries. It can also be used in some laboratory pressure testing and research scenarios.

Q: How stable is the backpressure valve?

A: The backpressure valve has undergone strict quality inspection and testing, and has excellent stability. Under normal use conditions, it can maintain stable pressure control for a long time to ensure the safe and reliable operation of the system.

Q: Is it complicated to install this backpressure valve? What do I need to pay attention to?

A: Installation is not complicated. When installing, you need to ensure the sealing of the connection ports and connect the piping and instrumentation correctly according to the product manual. At the same time, pay attention to the direction of installation to avoid the product not working properly due to wrong installation.

Q: How to operate the back pressure valve correctly?

A: When operating the back pressure valve, you can control the pressure level by adjusting the knob. During the operation, it should be adjusted slowly to avoid the sudden change of pressure causing shock to the system. Meanwhile, the working condition of the back pressure valve should be checked regularly to ensure its normal operation.

Q: Is this backpressure valve compatible with other brands of equipment?

A: In most cases, the R71 backpressure valve is compatible with other equipment that meets the relevant standards. However, in order to ensure the stability and reliability of the system, it is recommended to consult a professional technician or refer to the product manual before use.

Q: Does the backpressure valve require regular maintenance? How long is the maintenance cycle?

A: Regular maintenance is required. The maintenance cycle depends on the frequency of use and environmental conditions, and it is generally recommended that inspection and maintenance be performed every 3 to 6 months.

Q: How do I perform routine maintenance on my back pressure valve?

A: Routine maintenance mainly includes cleaning the surface, checking the connection parts for looseness, and observing whether the meter display is normal or not. If problems are found, repair or replace parts promptly.

Q: If the back pressure valve malfunctions, how to repair it?

A:If the back pressure valve fails, you should first stop using it and check the cause of the failure. If it is a small problem, you can repair it by yourself, such as replacing seals and cleaning the valve.
