A check valve built into the same body with a sequence valve is commonly called which of the following?

• A. Integral Check
• B. Bypass Check
• C. Reverse Flow Check
• D. All of the above

Answer: (A)

A check valve that is built into the same body as a sequence valve is called an integral check. The word integral signals that the check is part of the same housing as the sequence valve, forming a compact, combined unit that ensures one-way flow while helping maintain the intended sequencing of the circuit. This specific naming distinguishes it from a standalone or differently configured check valve. The other terms describe functions or setups rather than this built-in combination. A bypass check implies a path that bypasses something in the circuit, which isn’t the standard way of naming the integrated component with a sequence valve. A reverse flow check describes the valve’s purpose (preventing backward flow) but not the fact that it’s housed together with a sequence valve. And all of the above would only be correct if all terms were valid, which they aren’t in common hydraulic terminology.
