These top-of-the-line valves are comparable to Asco Red Hat 8210G Series and Parker Gold Ring 23C Series. They operate on electricity to automatically start and stop flow. The actuator is directly mounted to the valve body to minimize movement and reduce wear.

Normally open valves are open unless actuated.

Zero pressure drop valves don’t require a minimum pressure drop between the inlet and outlet for operation.

Flow coefficient (Cv) is the amount of water (in gallons per minute) at 60° F that will flow through a fully open valve with a difference of 1 psi between the inlet and the outlet.

These valves create one action, such as extending a cylinder. Apply voltage to the electrical connection to actuate. Also known as 3-way and 3/2 valves, they direct airflow from the inlet to your equipment and exhaust return airflow to create motion. In the off position, they exhaust air from the system, allowing equipment to reset so the action can be repeated.

Normally closed valves block airflow until actuated.

Valves with spring return actuation go back to their original position when voltage is removed. Valves with electric (solenoid) return actuation go back to their original position when voltage is moved from the first solenoid to the second solenoid.

Flow coefficient (Cv) is a measurement that indicates how much airflow can pass through a valve. When selecting between valves with the same port size, choose the valve with the higher flow coefficient to ensure it provides enough airflow to operate your system.
