Wafer-Type Manual Butterfly Valve for Drainage HVAC Light Industry

Wafer-Type Manual Butterfly Valve Used For Drainage HVAC Light Industry

This is a clamp-type manual butterfly valve, which is used to manually control the on/off and flow of media (water, gas, liquid, etc.) in fluid pipeline systems (such as water supply and drainage, HVAC, light industry, etc.). The following is a disassembly from the structure and function:

Core components & functions

Valve body (blue part):

Mostly made of ductile iron, it has high strength and impact resistance, suitable for clamp installation (bolts are used to penetrate the pipe flanges on both sides and clamp the valve body to fix it), saving space and flexible installation, suitable for narrow pipelines or renovation projects.

The internal black rubber is the valve seat seal, which cooperates with the valve plate to block the leakage of the medium when closed and ensure the sealing (rubber can be selected as EPDM, nitrile, etc. as needed, suitable for different acid, alkali and temperature media).

Valve plate (silver disc in the middle):

The core of the pipeline "switch", rotating around the central axis (0°-90°) to control the on/off / flow. Due to manual operation, the valve plate needs to be wear-resistant and corrosion-resistant (such as stainless steel or surface spraying), extend life, and cope with frequent opening and closing.

Actuator (black handle + valve body):

Manual drive: The black handle is the operating part. When it is turned, it drives the valve plate to rotate through the worm/gear transmission (the handle turns several times, and the valve plate turns 90°), realizing "open/close/adjustment". The structure is simple and reliable, does not require electricity/gas source, is easy to maintain, and is suitable for scenarios with low automation requirements.

Application & Advantages

Scenarios: Community tap water inlet branch pipes, small factory cooling water circuits, HVAC terminal equipment (such as fan coil units), etc. - For example, the kitchen drainage pipeline of a shop is manually shut off for maintenance; the small boiler water supply pipeline is used to adjust the water supply volume.

Advantages: Manual operation is intuitive, low cost, and suitable for small flow and low pressure scenarios; the clamp installation is flexible, and there is no need to significantly change the pipeline during transformation/repair; the rubber soft seal is suitable for clean media, with good sealing and low noise (quieter when water impacts the valve plate).

Simply put, this is a "manual control expert" that relies on mechanical structure + manual operation to solve the fluid control needs of small pipelines. It is economical and practical.
