Three way threaded globe valve application the v5013n is a three way threaded globe valve that controls hot water cold water and glycol solutions up to 50 percent concentration in heating or cooling hvac applications. A type of globe valve that has three pipeline connections to provide general converging flow mixing or diverging flowsplitting service.

Three way mixing valve diagram. Another style of globe valve body is the three way body sometimes called a mixing or a diverting valve. V5013bcf three way mixing and diverting valves 5 60 21294 fig. Typical zone hookup of v5013c diverting valve used to control flow through coil. Three way valve operation and limitations. A three way mixing valve is not recommended at point a since it would be on the pump suction side and create vacuum conditions rather than maintain atmospheric pressures. This post looks at design differences between l pattern and t pattern flow plus how handle position and range of rotation combine with porting to control flow.
A b and ab. What is a three way valve. The bather runs the water to the. Note that the distribution circulator is located between the mixing valve and the manifold station. This 2 valve diverter can be located in the center of a faucet that adjusts temperature with a single dial turned to the left for hot water and to the right for cold or it can be set between the taps of a 2 tap faucet. Variations include cage port and stemguided designs selected for high temperature service and end connections can be specified to mate with most piping schemes.
This valve design has three ports on it with the plug in this particular case a cage guided plug controlling the degree to which two of the ports connect with the third port. When the condenser is below the level of the cooling tower a bypass using a two way valve is recommended. These valves are defined by the number of ports they use. Three way ball valves simplify gas and fluid flow control. The choice of flow pattern or valve ball porting t port vs l port provides specific options. Three way control valves may be diverting or mixing depending on how they are ported and controlled.
2 way and 3 way valve classifications are commonly used in industrial applications. Valve installation threaded valve bodies line up the pipes squarely with the valve at each end. The resulting mix flows out through port ab and heads for the radiant floor manifolds. Mixing or diverting valve. Hot water enters port a and mixes with cool return water entering through port b. The valve is used for mixing service to direct flow from one of two.
If the pipes are forced into the valve the body may become twisted and improper seating will result. As the temperature from the terminal unit or coil is satisfied the flow rate is reduced in the coil and the flow is diverted to the bypass. An inlet port a and an outlet port ab on the other hand 3 way valves consist of three ports. 2 way valves as their name suggests consist of two ports. The sketch below shows a three way diverting valve system. The tee diverter is a single valve diverter located in the tub spout.
The proper piping of a three way thermostat valve is shown in figure 1.
