What is valve pressure testing, and why is it important?
Valve pressure testing is a quality control process that ensures your valves can withstand operational pressures without leaking or failing. It helps prevent costly breakdowns, safety hazards, and system inefficiencies, ensuring your valves perform reliably under real-world conditions.
What types of pressure testing do you offer?
We offer three main types of pressure testing:
- Hydrostatic Testing – Uses water to check for leaks and structural integrity.
- Pneumatic Testing – Uses compressed air or gas to detect even the smallest leaks.
- Seat Leak Testing – Ensures a tight seal when the valve is closed, preventing internal leakage.
How often should valves be pressure tested?
The frequency of pressure testing depends on the type of valve, application, and industry regulations. In critical applications such as steam, oil & gas, and chemical processing, valves should be tested at regular intervals to ensure ongoing reliability and compliance with safety standards.
What happens if my valve fails the pressure test?
If a valve fails testing, we provide a detailed failure report outlining the issue. Our team can then recommend repairs, refurbishment, or replacement parts to restore the valve to full working condition, ensuring it meets performance and safety requirements
When should a valve be repaired instead of replaced?
Valves can often be repaired if issues like leakage, sticking, or worn seals are present—especially when the valve body is still structurally sound and replacement would be more costly or time-consuming.
What parts of a valve are typically repaired or replaced?
Common repairable parts include seats, seals, gaskets, stems, and actuators. Internal cleaning, lapping, and re-machining may also be performed depending on wear.
What is valve pressure testing?
Valve pressure testing is the process of verifying a valve’s ability to maintain pressure without leaking under set conditions, using air, water, or other mediums.
What are the main types of pressure tests?
The most common tests include hydrostatic testing (with water), pneumatic testing (with air or gas), and seat leakage testing to verify sealing performance.
How long does valve repair typically take?
Repair time varies based on valve size, type, and the extent of damage—but typical repairs range from a few hours to several days, depending on complexity and part availability.
Why is pressure testing important?
It ensures valve reliability, safety, and compliance with industry standards—preventing costly failures or accidents in service.
