These three are the most-specified isolation and flow valves in industry. They are not interchangeable –picking the wrong one causes leakage, erosion or wasted energy. Here is how to tell them apart.
A gate valve uses a sliding wedge to fully open or fully close the path. Its strength is a straight-through, low-pressure-loss bore when open. It should stay either fully open or fully closed –never throttled.
A globe valve uses a plug that moves against a seat, letting you precisely control flow or hold a pressure drop. The trade-off is higher pressure loss than a gate valve. Use it where throttling is required.
A check valve is self-acting: forward flow opens it, reverse flow closes it automatically. No actuator, no operator. It protects pumps, compressors and piping from backflow damage.
Need simple open/close with low loss? →?Gate valve. Need to regulate flow? →?Globe or control valve. Need to stop reverse flow automatically? →?Check valve. Many systems combine all three in series for complete protection.
Not recommended. A partially open gate valve causes seat erosion and vibration. Use a globe or control valve for flow regulation.
Choose a globe valve when you need to regulate flow or hold a precise pressure drop. Choose a gate valve for infrequent full open/close isolation where pressure loss must be minimal.
No. Check valves are self-acting –they open with forward flow and close automatically when flow reverses, requiring no actuator or operator.
