What is the difference between a 2-way valve and a 3-way valve. (ans in not more thn 3 sentence)?
Answer:
a 2 way valve has one inlet and one outlet. 3 way valve has one inlet and 2 outlets. the choice of outlets will depend on the valve position. HOWEVER, a mixing valve is also a 3 way valve but we use the 2 outlets as inlets (2 different products) and the inlet as an outlet but with the 2 products mixed. The mixing ratio will depend on the valve position and how much of each product we allow to pass through.
A 2-way valve only allows incoming material one exit out of the valve. A 3-way valve allows incoming material to use one of 2 exits depending on where the valve is directed.
2-way has 2 ports and 2 positions (On/off)
3-way has 3 ports and 2 or 3 positions
two different kinds of 3-ways L=diverter, T=mixing
A 2-way valve is either open or closed by a lever turned through 90°.
A 3-way valve has an inlet and 2 outlet ports and is generally used for switching flow.
If two 3-way valves have their operators ganged together when used on a set of filters for example. When a filter gets a high DP, both the inlet and outlet flows can be switched simultaneously to the other filter.
