Normally Closed Solenoid Valve

Normally Closed Solenoid Valve

At Gould Solenoid Valves, we know that our customers have diverse needs and unique project requirements. One essential aspect that sets us apart is our comprehensive understanding of solenoid valve mechanics and specifications. Two distinct types of solenoid valves that our customers often inquire about are normally open (NO) and normally closed (NC) solenoid valves.

Normally Open Versus Normally Closed Solenoid Valve Comparison

In a normally open (NO) solenoid valve, the valve's default state allows fluid or gas to move freely through it. The unrestricted flow occurs when the solenoid coil is not energized, meaning that without an electrical power source, the pathway remains open. Once electricity is applied, the solenoid activates, the core shifts, and the valve closes, effectively halting the fluid or gas flow. NO solenoid valves have their unique set of applications, primarily in systems where an unimpeded, continuous flow of fluid or gas is a necessity, or when flow must be maintained in the event of a power failure. Examples could range from cooling systems, where continuous circulation is necessary, to irrigation systems that require constant water flow.

Contrary to this, a normally closed (NC) solenoid valve, by default, blocks the passage of fluid or gas when in its unpowered state. The design ensures that, without electrical power, the valve remains closed, acting as a safeguard against unwanted or inadvertent flow. When the solenoid is energized, the core is displaced, opening the valve and allowing the fluid or gas to flow freely. NC solenoid valves are typically used in applications where it's crucial to control the onset and offset of flow, often for safety reasons. They are a common choice for fuel lines, chemical processing, or any other application where the unintentional flow of fluid or gas could lead to potential hazards or wastage.

Choosing the Right Solenoid Valve for Your Specific Needs

Grasping the operational differences between normally open (NO) and normally closed (NC) solenoid valves is not just a matter of technical knowledge. It's a pivotal step in selecting the appropriate valve for your specific application. It's not just about controlling the flow of fluids or gases; it's about fine-tuning your operations to the last detail for optimal performance and safety.

Imagine a system where the default flow of a fluid is a critical part of the operation, such as a cooling system. The continuous flow of coolant is vital to prevent overheating of machinery or equipment. In such a scenario, a normally open valve, which allows for free flow when unpowered, would be the preferred choice. This way, even in the event of a power outage, the coolant flow remains unaffected, thereby avoiding potential damage.

On the other hand, think of a situation where the default state needs to block the flow, perhaps for safety reasons or to prevent leakage or waste. For instance, in a fuel supply system, you wouldn't want the fuel to keep flowing if the system is not operational or if there is a power loss. Here, a normally closed valve, which obstructs flow when unpowered, would be the more suitable option.
