What is Valve?

Valve is an application that controls the flow of the fluid or gas. It manages direction or controls the flow of a fluid or gas by opening and closing of various passageways.

Valves play a vital role in most of the industries involving pipelines or other applications. Some of the common industries having valves are oil, gas, petrochemicals, marine industry, and many more.

There are 6 different types of valves namely globe, gate, ball, butterfly, check, and plug. Every valve is differently designed based on the characteristics of the application and also the pressure. Therefore, different industries use different valves.

Why is Valve Testing important?

As valves are a crucial application in many industries, it is important that the valves function accurately i.e. directing the right pressure without leakages. There have been cases that these high pressure systems have exploded due to leakages or inaccurate pressure transfer. Thus, it is important to ensure that joint-integrity is maintained in such a high pressure system for safety and productivity.

Valve testing is conducted as a maintenance process to evaluate the condition or health of an operational valve. Following are the functions of a valve testing machine on a high pressure system:

  • Testing for any valve leakages
  • Seat and seal test
  • Seat leakage inspection
  • Suitability for fluid & Gas testing

Valve testing is generally conducted to rectify issues like mechanical friction, flashing, cavitation, choked flow, erosion, and noise in valve to name a few.

The benefits of these valve testing machines are that all the tests are automated that allows them to create a log of all past data. Additional features like rotating test benches, vacuum testing, customizable equipment based on requirements are also provided.

Why does a valve corrode or deter?

As valves are constantly being exposed to gases and liquids there is a high probability of the system to start corroding. Other common problems that occur are that minerals get accumulated to create leakages.

How frequently is valve testing required?

Depending on the pressure faced by the valve, testing should be ideally conducted anywhere from every two months to three years based on the application and the pressure it works on.
