Our Explosion Proof Stainless Steel Flanged Ball Valves are Ideal for Applications where there is a Flammable Process Fluid or Hazardous Dust or Gases in the Atmosphere. They are also suitable for applications where you need to rely on the integrity of your valves to provide consistent operation for long periods of time. The patented PFA* fused ball offers better corrosion resistance, a lower torque rating for easier handling and provides improved performance.
Dual certified explosion proof, low emission 316 stainless steel 2-piece 150# flanged investment cast ball valve mounts between standard ANSI 150 pound pipe flanges. Full port flanged connections allow for easy installation and are ideal for larger diameter pipe sizes. The PTFE seat allows for better sealing and prevents the formation of bacterial growth in sanitary applications. The teflon seat also reduces the possibility of leaking, sticking and corrosion that can occur when steam or acid-base chemicals are used.
The electric actuator is power-to-open and power-to-close. On receipt of a continuous voltage signal the motor runs and via the self-locking gear drive rotates the ball one quarter turn. On receipt of a reverse continuous signal the motor turns in the opposite direction, reversing the valve position. The position of the valve is confirmed by internal cams striking the limit switches.
The flange connection type is designed to be mated with another flanged connection and has a gasket between the body and the tailpiece. This design eliminates the possibility of the tailpiece unthreading or loosening in service and helps ensure the safety of personnel. Explosion Proof Stainless Steel Flanged Ball Valves
