Evolving control valve

08 June 2017

Routine wear and tear of traditional control valves can lead to downtime and underperformance, which can reduce process efficiently. When it designed the Spira-trol control valve ten years ago Spirax Sarco took a new approach to the transfer of steam and other industrial fluids to ensure greater durability and efficiency.

This resulted in the control valve being capable of controlling pressure, temperature and flow in industrial environments, helping to achieve energy savings with minimal total cost of ownership (TCO).

Spira-trol is a modular, ‘set and forget’ system. Its cage retained seat design allows maintenance procedures to be done quickly and efficiently, with no need for any special tools. The control valve can also be maintained in-situ without being removed from the line, minimising downtime and maximising productivity. 

Internal components of the control valve have been designed to withstand a range of industrial fluids, including steam that is highly corrosive. 

Electrically or pneumatically actuated, Spira-trol includes a range of smart positioners to aid accurate control valve positioning and improve efficiency. With the option of the bellows sealed bonnet, users can achieve zero emissions leakage and further reduce maintenance.
