Erie™ PopTop™ Series valve bodies and actuators provide easy installation for a variety of heating and cooling applications. The valve's actuator can be installed after the valve body has been installed onto the fan coil, baseboard, or air handler. VS Series valves are available for low-pressure steam applications. PopTop Series are two-position spring return valves. When powered, the actuator moves to the desired position, tensing the spring return system.

When power is removed, the actuator returns to the normal position. PopTop Series two-position spring return valves can be purchased with an optional built-in auxiliary SPDT end switch for interfacing or signaling. For example, zone pump burner control. Actuators are designed for cycling applications (not constantly powered).
