Common Challenges in Industrial Valve Maintenance and How to Overcome Them

Industrial valve maintenance may seem daunting, particularly when confronted with prevalent problems such as corrosion, wear, and high-pressure atmospheres. However, with the correct knowledge, you can directly face these challenges. Let's consider some maintenance tips to keep your industrial valves working at their best.

Dealing with Corrosion and Wear

Corrosion and wear are two common issues that you might encounter in maintaining industrial valves, emphasising the need for early detection. Here are some maintenance tips to help you effectively handle these issues:

  • Valve leakage is a common problem, often resulting from worn seals, damaged sealing surfaces, or incorrect installation. Regular inspections of the valve seals, gaskets, and sealing surfaces can reveal signs of wear or damage. If necessary, tighten the bolts or fasteners. If the leakage continues, you may need to replace the seals or address the root cause.
  • Sticking or binding valves can interrupt your operations. Debris, corrosion, or a lack of lubrication typically cause this issue. To fix this, clean the inside of the valve, lubricate it, and ensure that the valve components move without any hitches.
  • Excessive noise or vibration during valve operation could suggest a misaligned or improperly installed valve. Regular inspections, lubrication, ensuring sealing integrity, and maintaining the actuator are vital for the reliability of your plant's valves.
  • Internal inspections can reveal issues like cavitation and other internal damages that are not visible from the outside. Address these issues quickly to maintain the valves' proper functioning.
  • Do not ignore the wear condition of the sealing surface and the trapezoidal threads of the valve stem and valve stem nut. This should form a crucial part of your maintenance routine.

While these tips can help handle corrosion and wear, it's crucial to note that high-pressure environments pose their own unique challenges, which we will examine next.

Managing Maintenance in High-Pressure Environments

Managing industrial valves in high-pressure environments presents unique challenges. Actuated valves, crucial for precise flow control and process autonomy in high-pressure fluid service, enhance fluid flow applications by opening or closing at predetermined intervals, which offers remote control capabilities.

The kind of actuator which controls process valves through either rotary or linear motion is also essential. Actuators need an external power source to work. In manually operated valves, a lever handle or handwheel connects to the valve stem or a gearing system, delivering sufficient output torque to change the position of the valve mechanism. Powering valve actuation can be achieved through:

  1. Electric actuation
  2. Pneumatic actuation
  3. Hydraulic actuation

After grasping the role and operation of actuated valves, making the right choice is crucial. Evaluating flow conditions thoroughly and sizing the valve properly are necessary steps when selecting suitable valves for high-pressure fluid applications.

The actuator size required is determined by the maximum pressure of the pipe system and the force needed to operate the valve. It's also typical to specify the highest operating temperature along with the pressure for high-pressure valves.

One maintenance aspect requiring careful focus is the greasing operation. During this process, greasing pressure frequently changes between peaks and valleys. Low pressure might result in the seal leaking or failing. On the other hand, high pressure could clog the grease injection port, solidify the grease in the seal, or cause the sealing ring to jam with the valve ball and valve plate.

Safety should always be your foremost concern when maintaining industrial valves in high-pressure environments.

Valve Maintenance: The Closing Remarks

Maintaining industrial valves goes beyond a mere task. It's a vital responsibility that ensures operational efficiency, durability, and safety. Regular inspections, comprehensive cleaning, and suitable lubrication form the bedrock of this responsibility.
