Series 07TB Teflon Block Valve

AO-3607TB Acid proof control Valves

Teflon block valves are designed to be used for chemical injection service and acid or alkaline fluid service. This valve has very compact design assembled with multi-spring diaphragm actuator.

Performance

  • Integral body construction –All the wetted parts of the valve body are made of PTFE and realized superior anti-corrosive valve for acid or alkaline service.
  • Main body is covered with stainless steel case providing high durability and long life.
  • Compact design.
  • Wide Cv range and controllability
