The Polypipe PB00401 UFCH Valve Actuator is a normally closed electrothermal actuator designed to open and close heating circuits on Polypipe underfloor heating manifolds based on heat demand, enabling individual room temperature control for improved energy efficiency.

Product Description

The Polypipe PB00401 Valve Actuator is an electrothermal device that controls the flow in underfloor heating systems by opening or closing valves in response to thermostat signals. It uses a PTC resistor-heated wax element and compression spring for reliable operation. Normally closed, it opens when powered and features a first-open function for construction phase use. The actuator includes a built-in indicator for power and valve status, ensuring easy monitoring and maintenance-free performance.

Key Features

• Normally closed (NC): Opens when powered, with first-open function for initial use.
• Low power consumption: 1 W operating power.
• Snap-on installation: Simple 360° positioning with valve adapter system.
