Pressure Swing Adsorption

Hero Summary
Field-proven and lab-tested control valve assemblies from Flowserve are approved and trusted by the world’s leading licensors for high-cycle PSA applications.

Pressure swing adsorption (PSA) applications require control valves that maintain tight shutoff amidst high cycles and bi-directional flows. The violent nature of these processes and frequency of required cycling put significant strain on PSA valves.

PSA control valves can cycle as often as every 30 seconds, leading to stem or shaft breakage. In addition, inadequate actuator and positioner linkages can contribute to mechanical failure in high-cycle environments, increasing maintenance and unplanned downtime. 

 

PSA unit operators can optimize performance and maximize uptime in control and on/off applications by specifying licensor-approved Valtek® control valves and Logix™ automation from Flowserve.

Maximize PSA skid efficiency and profits 

The proven shutoff reliability of Valtek Valdisk™ and Mark One™ valves allows plant operators to maintain accurate pressure in PSA beds and extract purer hydrogen, oxygen and nitrogen (or other gases). Increased gas purity and capacities lead to greater production and higher profits.

Extend service life and lower total cost of ownership

Costly downtime is reduced and turnaround cycles can be extended as a result of the long service life and minimal wear of Valtek Valdisk and Mark One valves. These valve assemblies are RedRaven Ready, which means maintenance intervals and lifecycle costs can be further improved with Flowserve’s IoT-enabled, advanced predictive maintenance solution.

Selecting the Right Valves for PSA Applications

There are typically three types of valves used in PSA operations: isolation, on/off and control valves. When selecting valves for PSA applications, it's essential to understand what these valves do and what performance criteria to consider.
