Overview

Two way on-off line voltage valves consist of an actuator motor and valve assembly for controlling the flow of hot or chilled water.

Features

Manual opener (on all models, except straight-through, normally open valves) for valve operation on power failure; valve returns to automatic position when power is restored.
All models may be installed without disassembling the valve.
Compact construction for easy installation.
Complete powerhead may be removed or replaced without breaking plumbing line connections or draining the system.
Motor may be replaced without removing the valve body or draining the system.
Suitable for heating and cooling applications.
