Spira-Trol control valves have extended options to ensure that the valves can be optimized for a specific customer application. Pneumatic-piston actuators have been added to the diaphragm and electric actuator ranges. The free-float design provides users with longer stem-seal life and improved valve shut-off performance. Spira-trol valves also now feature better capacities and a balanced trim option for high differential pressures. The valves are now additionally available in 6- and 8-in. sizes, due to high demand, says the company. — Spirax Sarco Inc., Blythewood, S.C.
