Valtorc has released new spring return fail safe automated knife gate valves. The spring return cylinders are available in 316SS, carbon steel Epoxy ends and can work with knife gate valves up to 20″. The spring return linear cylinders can be designed “Man Safe” captured springs—meaning the unit can be easily dismantled and repaired on site without special equipment.
As per standards, the spring return cylinders are welded shut to prevent tampering and accidental removal of the end caps. The spring options are available in spring to close or spring to open.
