Limitorque LPS Pneumatic Scotch Yoke Heavy-Duty Actuators
Limitorque LPS Pneumatic Scotch Yoke Heavy-Duty Actuators retrofitted to existing DN600 inlet butterfly valves to prevent untreated raw water passing into and through the plants without chemical dosing. The Limitorque actuators will enable the plant to implement a ‘fail close’ strategy for the inlet valves.
Additional features incorporated include custom valve closing times;
• 0-75 degrees – 5 seconds (minimal impact to flow through and head across the valve)
• 75-90 degrees – 15 seconds (most flow control and head loss through this portion of travel)
