A: Standardized M30×1.5 Connection for Seamless OEM Integration

Connection Standard:
The actuator utilizes the industry-standard M30×1.5 threaded nut connection.

Universal Compatibility:
This standardized interface ensures seamless compatibility with the vast majority of underfloor heating manifolds, central air conditioning water system valves, and various small-scale terminal valves on the market.

OEM Cost Optimization:
This universal design significantly reduces hardware adaptation costs and simplifies inventory management for OEM clients.

A: Selection Logic Based on Control System Initial State

NC vs. NO Logic:

Normally Closed (NC): The valve remains closed when de-energized and automatically opens upon power activation.

Normally Open (NO): The valve remains open when de-energized and automatically closes upon power activation.

OEM Procurement Advice:
Since these specifications are fixed during the hardware manufacturing process, it is mandatory for the purchasing party to specify the required model based on their thermostat system's preset logic prior to placing the order.

A: Silent Operation Based on Thermal Expansion Principle

Acoustic Performance:
No. The actuator operates based on the thermal expansion principle, ensuring completely silent operation during both opening and closing cycles.

Core Advantage for Premium Integration:
This is a core advantage for HVAC system integrators targeting high-end residential bedrooms or professional office environments where acoustic comfort and a premium user experience are paramount.
