Three-, four- and five-way ball valves are called multi-port valves. The three-way ball valve is the most common multi-port ball valve. A three-way ball valve has three ports or openings that are connected to piping or tubing for gas or fluid flow (media) to pass through.
A 3-way spool valve can be used as a 2-way valve by blocking one port. Poppet valves are made in 2-way, 3-way, and 4-way configurations. Valve Operation. Two Way Valves. Two-way valves turn air on and off in applications such as shop air, branch airlines, supply pressure to systems, and supply air to tools, motors and similar equipment.
INSTALLATION & OPERATING INSTRUCTIONS. Valve positioning. Install the valve so the actuator head is not below the horizontal level of the pipework. The open vent and cold feed must not be isolated. The flow must be in the direction of the arrow. (from the centre port to either Port A or Port B). Fitting the valve body to the pipework.

3/2-way valves 3/2-way valves are mostly used to control single acting actuators. They can be normally closed or normally open. In the scheme below you can see two applications. 1. An electrically actuated 3/2-way valve (S1) controls the single acting cylinder (C1).
2 and 3 port Spring Return Motorised Valves Installation Instructions. Applications. The ZA-V2..2 port zone valve is available in 22 and 28mm pipe sizes. It is suitable for zone control of central heating and hot water primary circuits.
Flow Pattern Diagrams. The diagrams show the top view as though you were looking down on the stem. White areas indicate the path available for process flow. Shaded areas indicate unused ports for a given flow position. Diverter Port Patterns.
