Spirax Sarco's Spira-Trol control valve range is available in six- and eight-inch sizes
Spirax Sarco's Spira-Trol control valve range is available in six- and eight-inch sizes with more control options. The valves are engineered to be easy to maintain and do not require any special tooling due to the ‘clamp-in-seat’ design. The number of options has also been extended. Pneumatic piston actuators have been added to the diaphragm and electric actuator ranges. The free float design is engineered to provide the user with longer stem seal life and better valve shut-off performance. The valves are also designed for improved capacities and feature a balanced trim option for high differential pressures.
