The Right Solenoid Valve for Any Job

HVAC solenoid valves rely on an electromagnetic coil to instantly move the plunger to either open or close the valve. However, choosing the right valve for your project depends on its default state when unpowered.

Normally Closed (NC) Solenoid Valves

We carry normally closed valves that remain securely shut until power is applied, making them the ideal option for fail-safe applications where it is important to prevent flow in the power-off state. NC solenoid valves provide fail-safe automatic shut-off, making them ideal for safety-critical HVAC applications. These valves will also prevent fluid leakage when the system is inactive. Their fail-safe design makes NC valves widely used in HVAC systems.

Normally Open (NO) Solenoid Valves

Normally open valves will continue to allow fluid or gas to pass through them until energy is applied to shut them off. These solenoid valves ensure that a line can vent and drain even during a power failure. You can shop for these HVAC solenoid valves for system draining or bleed lines that need to remain open in their power-off state. 

The NO valves are ideal for applications that rely on continuous-flow processes and only need to be shut off periodically. They are also an energy-efficient option for operations where the valve must almost always remain open.
