Severn Glocon has received a second order for innovative control valves, known as Switching Valves, that are specifically designed for use in hydrogen production plants The new order reinforces the success of these valves, which have been developed by Severn Glocon for the demanding duties encountered in the PSA (Pressure Swing Adsorbsion) process

Specialised valve design for Hydrogen plant PSA
"Switching valves" are used in the PSA (Pressure Swing Adsorption) process that removes impurities from the hydrogen rich gas manufactured in steam methane reforming plant in a new plant in Italy
Solution for valve fugitive emissions control
Severn Glocon has developed an innovative solution for positive valve stem gland security, enabling changes in performance to be safely monitored during the service life of the valve
The process removes impurities from the hydrogen rich gas produced in steam methane reforming plants.
After an accelerated development and testing programme lasting more than six months, the valves were first ordered by Axsia Howmar in 2003 for a plant at an Italian refinery.
The new order is for another Axsia Howmar hydrogen generation plant now being built in the Czech Republic.
This order includes a new butterfly valve development of the original globe valve version of the Severn Glocon Switching Valve.
In customer witnessed testing at the Severn Glocon factory, the butterfly valve version successfully achieved more than one million operating cycles before it was specified for the new plant.
The tests were essential since the PSA process operates in a cyclic manner and calls for very rapid stroke times with a bubble-tight shut off for flow in both directions.
The application therefore demands special attention to the design and selection of materials for valve and actuator components.
In addition, valves for the Czech Republic plant must be suitable for low ambient temperature operation down to minus 33C.
Meeting this requirement dictated the use of low temperature carbon steel for valve components and special seals in the pneumatic actuators.
In total, Severn Glocon is supplying twelve globe type and four butterfly type Switching Valves in sizes up to 6 inches, together with three conventional control valves, on the latest contract.
