A 4-way valve is a type of valve with four ports used to control the direction of fluid flow. It is primarily used in systems where fluid needs to be redirected between multiple pathways, such as in hydraulic or pneumatic systems. A 4-way valve is often essential for reversing flow, actuating double-acting cylinders, or controlling fluid movement in complex systems.
** Operating Principle
A 4-way valve typically consists of four ports:
Two inlets (or supply ports)
Two outlets (or return/exhaust ports)
The valve directs fluid from one or more inlets to specific outlets based on the control mechanism (e.g., a spool or a rotary control inside the valve).
