Schneider Electric VM Series PopTop™ Modulating Valves

Modulating Valves
VM Series PopTop™

The Schneider Electric Modulating PopTop™ Series valve actuator assemblies are designed for closed hydronic heating and cooling systems. The Modulating PopTop is used to control fluid flow in fan coil units, VAV reheat, unit ventilators, AHUs and radiant applications. The Modulating PopTop Proportional (P) type is compatible with any 0 to 10 Vdc or 4 to 20 mA signal with jumper selectable operating range and action resulting in precise positioning. The floating (T) type is compatible with any 24 Vac three-wire signal when three minute time-out logic resides in the valve actuator or system controller. The Modulating PopTop valve assemblies allow the actuator to be snapped on to, or off from, the valve body. The actuator can be mounted after the valve body has been installed into the system without the need for linkages or calibration. Available in standard (non-spring return) and spring return modulating actuators. The two-way spring return modulating actuators are provided in either normally open or normally closed operation. The three-way valves are available in normally closed operation only. Valve body reversal provides normally open flow for three-way valve bodies.

• Magnetic clutch to maximize the life of the motor and gear train
• Manual operating lever/position indicator facilitates field setup
• Easy to use lever terminal blocks
• Actuator can be installed after the valve body
• Three wire floating and 0 to 10 Vdc or 4 to 20 mA proportional available
• Spring return will return actuator to normal position when the power is lost for more than two minutes



1 When ordering valve body only: use the first six positions to configure the valve.
2 When ordering actuator only: use the last seven positions to configure the actuator.

3 Voltage A = 24 Vac Only Electrical Leads 00 = No leads Temperature Ratings 3 = General Temperature This feature is standard for spring return actuators. It must be included in the part number.
4 Should not be used with thermostats/controllers unless they have a timeout feature.
