Designed to meet the demands of today’s industries, the Spirax Sarco Spira-trol control valve is robust, innovative and cost effective.
Adaptable to Your Needs
The Spira-trol control valve has a modular design concept, which can incorporate many options within a single body envelope. This leads to a low number of components and a highly flexible system, where one valve can satisfy the needs of numerous industrial requirements. The outcome for the user is a general service control valve with an exceptionally low cost of ownership.
Robust, Innovative and Cost Effective
Increased stem seal life
Top and bottom guided valve stem ensures excellent alignment and long stem seal life. Scraper and dust rings ensure the stem seal is not damaged by the flow media or particles form the atmosphere. Viton 'O' rings ensure excellent sealing in low pressure and temperature media.
Long-life valve internals
When compared to alternative designs, the cage retained seat and plug of the Spirax Sarco Spira-trol provides the user with better valve shut-off performance and reduced leakage across the seat. Hard trim materials as standard, designed for steam, giving a high resistance to erosion and corrosion on an extensive range of media. Large gallery area reduces the flow velocity, body erosion and noise output.
Hassle free - with quick and easy installation and low maintenance requirements
All trim components are designed to clamp in place so the valve can quickly be configured to the user’s specific process needs. During assembly the seat and plug are self-aligning using the clamp in place cage retained design. The simplicity of build also means that maintenance is quick and easy, with no special tools required.
• Quick to configure
• No special tools required
• Design performance easily achieved after maintenance
SP400 and SP500
The smart solution
Reduce energy consumption with the ultra-efficient SP400 and SP500 positioners. These smart digital positioners consume
approximately 1 % of the air of a traditional electropneumatic positioner and have class-leading low impedance helping to save on
Hall effect contactless feedback, giving a zero lag between feedback and position, eliminating hysteresis.
Simple single button push to commission - quick and easy to set up, requiring no specialist training or skills.
Highly efficient positioner, with the lowest steady state air consumption on the market - increases profitability, reduces electricity cost and lowers CO2 emissions.
