Understanding check valve sizing is crucial to ensuring proper flow and optimal efficiency of your fluid, steam, or gas flow system. To get the most out of your check valve, you need to know which check valve types are suitable for the environmental factors or your application.
Check valves should be sized according to their application and flow, rather than solely based on their line size. Selecting an appropriately sized check valve ensures it operates at its peak, delivering efficient service with maximum protection. Proper check valve sizing enhances a system’s reliability, offering the longest and most trouble-free service.
Undersized Valves
To small of a valve will result in higher pressure losses, restricted flow and could generate excessive noise and vibration.
If the check valve is too small for the pipe, it's like having a tiny door for a big crowd – it creates a bottleneck. This means the fluid or gas flow will be restricted, causing pressure buildup and potentially damaging the valve or the system.
Oversized Valves
To large of a valve may cause premature wear and failure of the valve’s internal components.
If the check valve is too large for the required flow, it's like having a huge door for a small room – it's inefficient. The valve will operate in a partially open position, fluttering in the flow or chattering, both situations causing premature failures and possible equipment damage.
