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.

Model: VB-7313-000-4-PP
Screwed NPT Straightaway Mount Three-way Mixing Valve
Mixing valves have two inlets and one outlet and are configured for combining two fluids. This is our most popular series of mixing valves. The valve body has female pipe thread at both inlets and the outlet. These valves are available in 1/2" through 2" pipe size.

Factory assembled valves are available with hydraulic and electric actuators.

Model: VB-7314-000-4-PP
Union sweat straightaway three-way mixing valve
Mixing valves have two inlets and one outlet and are configured for combining two fluids. These valves have unions designed to be sweated to copper pipe. These valves are available in 1/2" through 2" pipe size.

Factory assembled valves are available with hydraulic and electric actuators.

Model: VB-7323-000-4-PP
Screwed NPT Straightaway Mount Three-way Diverting Valve
Diverting valves have one inlet and two outlets and are configured for diverting a fluid to two different locations. The valve body has female pipe thread at both outlets and the inlet. These valves are available in 1/2" through 2" pipe size.

Factory assembled valves are available with hydraulic and electric actuators.

Model: VB-9313-000-4-PP
Screwed NPT Straightaway Mount Three-way Mixing Valve
Mixing valves have two inlets and one outlet and are configured for combining two fluids. This is a continuation of our popular VB-7313 series. The valve body has female pipe thread at both inlets and the outlet. These valves are available in 2-1/2" and 3" pipe size.

Factory assembled valves are available with electric actuators only.

Model: VB-9313-000-5-PP
