Lordahl PF2-1 Actuator Valve

Product Description

The LORDAHL PF2-1 is an actuator valve designed for use in hydronic and fluid control systems. Actuator valves of this type combine a motorized actuator with a flow-control valve body, allowing automated open/close or modulating control of water or fluid flow through a piping circuit. This part is typically installed by licensed plumbers or HVAC technicians as part of zone control, radiant heating, or hydronic distribution systems. At 2.8 pounds, it is a compact, field-ready component suited for residential and light commercial applications.

The PF2-1 actuator valve is used in hydronic heating and cooling systems where automated flow control is required. Common installation scenarios include zone valve applications in multi-zone forced hot water systems, radiant floor heating loops, and fan coil unit piping. It is suitable for residential and light commercial environments where reliable, repeatable valve actuation is needed to manage fluid distribution across multiple zones or circuits.
