The Importance Of Vent Valves

In any type of closed system where there is the risk of pressure building up above a specific maximum limit, it is critical to have the correct vent valves in place in the system. Most types of vent valves are designed either for locations on tanks or strategically placed in pipelines and processing systems, making them a common valve required in the Texas oilfields.

What to Consider
It is possible for vent valves to also operate as a pressure only valve. The exterior of these two options is the same, but the pressure only valve does not offer the vacuum breaker options on the internal plunger.

Regardless of the presence of the internal plunger and vacuum breaker or if it is optional in the valve, the actual design, and materials used in the valve are essential considerations. Look for valves that are constructed with high tensile strength aluminum for the housing or body of the valve as well as for the flange attachment to the tank or vessel.

The same is true for inline styles of valves, with aluminum offering the necessary strength to weight ratio to avoid the pipe bowing or stress issues in the pipe. The choice of aluminum also means high corrosion resistance, an important factor for any type of part or component in the oil and gas industry in Texas.

Finally, check to make sure the vent valves under consideration are going to be practical to maintain and install in the field. The best designs have a lid and clean-out process that is easy to work with, and they also use a clip-in pressure seat for easy and secure installation.
