Description
The Kofloc Model 2203 Variable Secondary Pressure Flow Controller serves as an essential tool for engineers who face the challenge of unstable backpressure. In many chemical and analytical processes, the resistance at the outlet can change—whether due to a rising liquid level in a bubbling tank or a fluctuating pressure inside a reaction chamber. The Model 2203 automatically compensates for these changes to prevent flow drift.
This mechanical controller functions by maintaining a constant differential pressure across its internal needle valve. When the secondary pressure increases or decreases, the internal diaphragm of the Kofloc Model 2203 Variable Secondary Pressure Flow Controller instantly reacts to adjust the internal valve balance. This results in a stable mass flow that is independent of outlet pressure variations. Its pure mechanical operation means it requires no electrical power, providing a fail-safe and explosion-proof solution for sensitive industrial and laboratory environments.
