Industrial equipment with intermittent operation

Manual butterfly valves are very suitable for some industrial equipment that does not need to adjust the flow frequently and only needs to be switched on and off occasionally. For example, the backup cooling water pipelines of some factories are usually closed and only need to be opened when the main cooling system fails. Manual butterfly valves do not require complex automatic control systems. Operators can manually operate at any time according to actual conditions to quickly open or close the valve.

HVAC system

In the HVAC system of a building, manual butterfly valves can be used to adjust the flow of air and water. For example, at the terminal air outlet of a central air conditioner, the air volume sent to each room can be adjusted by a manual butterfly valve, thereby achieving control of indoor temperature and comfort.

It is simple to operate and easy to maintain. Property management personnel can make manual adjustments according to different seasons and room usage without relying on complex automatic control equipment, reducing the cost and maintenance difficulty of the system.

Water supply and drainage system

In the water supply and drainage pipelines of a building, manual butterfly valves are often used for the inspection and maintenance of local pipelines. When a section of the pipeline needs to be repaired or replaced, the water flow can be cut off by closing the corresponding manual butterfly valve to avoid water leakage. Manual butterfly valves are easy to install and flexible to operate. They can respond quickly in emergency situations to ensure the normal operation of the water supply and drainage system.

Irrigation system

In agricultural irrigation, manual butterfly valves can be used to control the direction and flow of irrigation water. For some small farmland or greenhouse irrigation systems, manual butterfly valves can meet their simple irrigation needs. Farmers can manually adjust the valve opening according to the water demand of crops to achieve precise irrigation. Moreover, manual butterfly valves are not restricted by power supply and can be used normally in some remote areas or places with unstable power supply.
