Avoid Compromises with Customized Flow Monitors and Excess Flow Valves   

Avoid Compromises With Customized Flow Monitors And Excess Flow Valves   

Even though they’re essential in many gas or liquid systems, flow monitors and excess flow valves (EFV’s) are often overlooked during the design phase. Too late it’s realized that standard catalog items don’t fit quite the way expected or don’t perform exactly as needed. The result is either last minute changes that add cost or acceptance of suboptimal performance for the life of the system.

It doesn’t have to be this way. Although customized monitors and valves might appear expensive the reality is they often lower costs while improving performance.

When to consider customization

Many situations warrant consideration of customized flow monitors and excess flow valves. Top three most common needs for customization:

  1. Non-standard material is needed to handle media and/or environment
  2. Standard item does not fit (line size, FNPT/MNPT)
  3. Quick connect/disconnect needed for easy life-cycle maintenance
