Concept Identification for Future Powell Valve Closure Systems

Every Powell Valve Closure System, whether intended for 90 ton tank cars or 150 pound cylinders of hazardous chemicals, has undergone a complete design and testing procedure before the first system is ever sold. By doing this, we can ensure that every future system will share the same quality, reliability and durability you would expect to find in a Powell Valve Closure System.

The procedure starts with a need. Our customers have indicated the need for various systems aimed at the emergency closure of valves on containers of numerous different hazardous chemicals.

Once we understand the need, we gather a team of experienced professionals to determine the best path to fill the needs of our customers. This planning stage can take months before a viable system is identified. During this period, we research every aspect of the particular chemical, container and valve combination in question.

Next, a design is produced in Powell’s CAD Department using the latest state-of-the-art drafting software. By utilizing the latest analysis features, we can identify the appropriate materials, dimensions and working clearances before the first prototype is built.

Still, no drawing can answer all the design and development questions that must be addressed before any new emergency valve closure system is put on the market. So, a prototype system is then fabricated. This system is then evaluated as described in following articles:

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.
