MX Series Large Flow Proportional Mixing or Diverting Valve.
Protects People and Equipment, Saves Energy
The MX Series is a state-of-the-art mixing valve with Teflon wear
surfaces to prevent calcium buildup. Valve controls hot and cold
supply based on control setting. If cold water is shut off, the valve
will reduce the mixed flow rate in seconds (speed/residual flow
rate varies by size). Accurate control of temperature provides
energy savings, increased comfort and safety for the user.
• Dual purpose mixing or diverting valve.
• Constant water temperature under different operating conditions.
• Proportional valve (control of hot and cold water).
• Flow reduction in seconds if cold water supply is interrupted.
• Maintains temperature with extremely low minimum flows.
• Temperature adjustable, tamper evident.
• Install in any position, heat trapping not required.
• Recirculation connection for fast response.
• Bronze/stainless construction.
• Wear surfaces Teflon coated to prevent deposit build-up.
• Union/tailpiece connections included.
• Tapped flange connections 2-1/2 in. and 3 in.
• Allen wrench for temperature adjustment included.
• ASSE 1017 approved (Union Models)
