This Vortex Roller Gate features a valve body constructed of 6061-T6 aluminum with a 304 stainless steel blade and seal retainers. Material contact is 304 stainless steel and polymer.
PET side seals and upper and lower bonnet seals are live loaded and silicone rubber backed. The valve blade is electropolished to handle sticky materials.
The valve features a fail-safe closed assembly for operation of valve one-time on loss of air supply. Upon electrical failure and a loss of plant air, the single solenoid valve will shift, allowing the compressed air to flow from the reserved tank, through the solenoid valve to the double acting air cylinder closing the game.
