Manual Air Vent & Drain Valve for Manifold Maintenance Systems

SHUANGLIN VALVE Service & Flushing Solution

Product Overview

The Manual Air Vent and Drain Valve from SHUANGLIN VALVE is designed for system maintenance control points in heating and water distribution systems.

Unlike automatic venting units, this model provides manual operation control, allowing technicians to precisely manage air release and drainage during system commissioning or maintenance.

It is widely used in manifold stations and HVAC service points where controlled intervention is required.

Functional Design

The top structure allows manual venting of trapped air when needed, while the bottom outlet is designed for controlled drainage or flushing operations.

This configuration gives installers full control over system balancing, especially during initial startup or periodic maintenance cycles.

The compact design makes it suitable for tight manifold cabinets where space is limited.
