Field Testing

Every Powell Valve Closure System is subjected to a complete development program to guarantee the highest quality, durability, and reliability available in a valve closure system. Whether aimed at 90 ton railcars or 150 lb cylinders, Powell’s development procedure for all new valve closure systems isn’t finished once our exhaustive in-house testing is completed. In addition to our computer controlled actuator test bench, Powell also completes rigorous testing of the entire system in the field, on the actual tank cars or chemical containers where the valve closure systems will eventually be used by our customers.

From exhaustive durability testing to stringent field testing, Powell offers valve closure systems that are reliable during the critical times you need them the most.

By testing our valve closure systems in actual service before making the system available on the market, we can identify field issues that might otherwise be difficult to anticipate during our in-house testing. Issues such as corrosive chemical contamination of the equipment, weather effects, and user abuse can be evaluated under the same conditions that can be expected in a customer's application. Even though the field testing period takes time, the resulting reliability and durability more than justify the delay of making the system available to our customers.

If it's a Powell system, you have complete protection that will last.

Shutdown Systems for Various Container Sizes

Powell is the only manufacturer to offer both pneumatic or electric systems for both small (150 lb - 1 Ton) to large container sizes (20 Ton Bullet Tanks to 90 Ton Railcars).

Powell offers several brackets designed to adapt to a variety of valve types, making the systems compatible with an extensive list of hazardous gasses. Powell can design, engineer and test prototype brackets upon request.
