Three-way Valve Bodies

Introduction
Valve bodies are available in three-way configuration as mixing and diverting valves. Sizes range from 1/2" to 6" pipe size or 5/8" O.D. SAE 45º copper tube.

    Selecting the proper valve body requires
    the following data:
  • Fluid type
  • Fluid temperature
  • Port size (Cv rating)
    Selecting the proper port size requires
    the following data:
  • Inlet pressure
  • Required flow rate in either GPM (liquid) or lbs/hr (steam).

If the customer is using on-off control, just select the valve body with the largest port size in the requested pipe size. Remember the following rule when sizing the valve for proportional control. “At least one-half of the available pressure must drop across the valve body when the valve is fully open.” An oversized valve body will result in very nonlinear control action. It is better to have too small of a valve body than too large of one. Please refer to the section on valve sizing (beginning on 5- 37) for complete data.

Model: VB-7312-000-4-PP
Flared Straightaway Mount Three-way Mixing Valve
Mixing valves have two inlets and one outlet and are configured for combining two fluids. This series is designed for connection to copper tubing rather than pipe. Mounting is designed for tube with a 5/8" O.D. SAE 45° flare. Cv ratings of 2.2 and 4.4 are available.

Factory assembled valves are available with hydraulic actuators only.
