What does it refer to when the Hycheck Valve has 'Checking' capabilities?

• A. It allows flow in only one direction
• B. It allows flow in both directions
• C. It blocks flow completely
• D. It senses pressure

Answer: (A)

The key idea is one-way flow control. When there’s forward pressure, the Hycheck Valve opens and lets fluid pass. If pressure would push the fluid backward, the valve closes to stop backflow. This “checking” action prevents reverse flow, helping keep the transfer line primed and protecting the supply from contamination. It’s not designed to allow flow in both directions, and it doesn’t simply block flow entirely. While it responds to pressure differences, its main function is preventing backflow, not sensing pressure as a separate capability.
