The eccentric rotary plug design provides excellent throttle control accuracy, low dynamic forces, and tight closure. Straight through flow pattern leads to high flow rate.
Corrosion resistance:
PFA linings with small wall thickness are resistant to most corrosive fluids.
Reduce unorganized emissions:
The rotary design essentially reduces packing wear compared to a typical linear valve. In addition, the standard design includes PTFE/ graphite coil root, V-ring supported by double O-ring follower to provide stepwise reliability in corrosive applications.
Easy to maintain:
The compact size and lightweight design allow for easy installation and removal without compromising pipe force.
Reliability:
Dovetail grooves provide mechanical anchorage between the metal body and the PFA lining to ensure high performance in vacuum and high temperatures. Powerful, field-proven rolling diaphragm actuators provide product fail-safe operation. The actuator linkage is fully enclosed with a combination handwheel and an adjustable limit stop with a locking mechanism. All actuators are provided with a complete range of options and accessories.
Size:
1" to 3" (25 to 80 mm)
