Difference Between Normally Closed Valves & Normally Open Valves
Normally closed valves are designed to block flow through the valve and are commonly used for emergency safety. During usual operation, these devices use a spring to remain closed. The valve will open when the system begins to experience overpressure to ensure safety. Once pressure begins to normalize, it … 展开
Normally open valves are also used as safety devices. However, unlike normally closed valves, these parts work to maintain low pressure in a system. Normally open valves are designed to allow liquid or gas to flow through in usual circumstances. As the … 展开
