What Is a Stack Valve?
A stack valve is a device designed to regulate fluid flow in various applications.
It comprises three primary components: the valve body, spool, and spring. The valve body, constructed from robust materials like metal or plastic, houses fluid passages within its hollow design. The spool, maneuvering inside the valve body, is responsible for controlling fluid flow. The spring maintains the spool in its designated position, ensuring precise flow regulation.
The operational mechanism of a stack valve is straightforward: fluid flow is halted when the spool obstructs the passage, effectively closing the valve. Conversely, fluid flows unimpeded when the spool aligns with the passage, opening the valve.
