Spirax Sarco’s Spira-Trol general service control valve has a fully modular design with a two-port control valve engineered for refined performance with a wide range of applications including food and beverage.
The Spira-Trol uses a low number of components, creating a highly flexible and maintainable system where one valve can satisfy the needs of numerous industrial requirements. Both ANSI and EN versions share the same internals, and only three pneumatic actuators are required for valves up to 100 mm in size. There are many options within this one body envelope, from low noise and low flow applications, to high temperature and zero emission requirements.
Self-aligning and clamp-in-place internals increase ease of maintenance. Hard trim materials and modular design diffuse the discharge from the plug and seat, as well as reducing internal flow velocities to minimise internal erosion. This ensures long stem seal life, extends valve life and reduces valve maintenance.
Additional valve options include electric, pneumatic or modulating actuation; external control system interface; noncontact feedback positioners; low noise, soft seal or hard facing trims amongst others.
