Resilient Seated Manual Butterfly Valve

Brand: A-T Controls, Inc.
Butterfly Valves cover a wide range of industries from General Purpose to Chemical, Food and Beverage, Pulp and Paper, Waste Water applications and more. 

A-T Controls Butterfly Valves are designed to comply with MSS-SP-67 and API-609 and are tested to comply with API-598 standards. They are compatible with ANSI 125/150 flanges.
Features
  • Each body is cast, precisely machined and epoxy-coated to meet rigid tolerances. 
  • Multiple seat and disc material options are available to meet a wide variety of process applications. 
  • Square Stem design facilitates direct mounting of actuators. 
  • Each stem is machined to fit tightly into the upper disc for smooth operation and minimal hysteresis. 
  • Bushings are available in PTFE and lubricated bronze. Both are corrosion resistant with mimimal effect on valve torque.
