IB/SB Series: Bellows Valves

Overview

In addition to the use in gas supply system, IB Series offers various valves that have special features such as high temperature-durable, high corrosion-resistance, variable flow, etc. for the use in exhaust piping. Shape of the seat has been changed to achieve reduction of particles, higher durability and further improvement. To select manual valve for the similar application, we recommend SB Series that is replacing the previous type.

Valve Features

  • The valve is designed to minimize the dead volume
  • Handles : 3 different types, i.e., standard type with/without open/close indicator, 90° open/close with lock function are available
  • Installation can be made either by panel-mount or bottom-mount
