Project Description

Teflon Block Valve

KOMOTO® 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-sprig diaphragm actuator.


  • 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.
