Groove gate valve
Overview of Groove Gate Valve
Groove gate valve is an industrial valve that uses groove type (clamp) connection. It has the characteristics of fast installation, safety and reliability, and is not limited by the installation site. It can solve the displacement problem caused by different axes and temperature differences in pipeline connections, and has vibration isolation and sound insulation performance. Its structural design supports full diameter and flow resistance characteristics, and is widely used in fields such as fire protection, water supply and drainage, petrochemicals, and coal mines.
Main types and characteristics
Bright stem gate valve
Structure: The valve stem is exposed, and the opening and closing status is visually displayed through the threaded position, making it easy to maintain.
Advantages: Convenient lubrication, suitable for scenarios that require frequent operation.
Concealed stem gate valve
Features: Compact structure, valve stem not exposed, suitable for installation environments with limited space.
Applications: fire protection systems, municipal engineering, etc.
Signal feedback type gate valve
Function: Equipped with an electrical signal output device, it can remotely monitor the status of valves.
Applicable: Automatic sprinkler fire protection pipelines, chemical pipelines, etc.
