Adaconn(TM) and Inserta(TM) have introduced the D03 Sandwich check valve module at the IFPE Show, in Las Vegas, Nevada in March 2008. These D03 Check valve compact modules may be ordered with up to two of the ICS check valve inserts. Valve orientation is reversible as required in the application. Steel construction allows for use in systems up to 5000psi. In-Line flow minimizes pressure drop and wasted horsepower. These valves may be ordered with orifices to provide economical fixed flow control.
