Operating Principle
This check valve allows fluid to flow in one direction only. A spring-loaded internal element opens when the inlet pressure exceeds the 5.5 bar setting. When pressure drops or flows from the opposite direction, the spring pushes the sealing element back into place, blocking reverse flow.
This ensures protection against backpressure and prevents damage to sensitive components. For the mechanical seal to engage effectively, a pressure differential of at least 25 bar is required.
