Parameter:
The grooved butterfly valve is driven by worm-gear and stem. Then the cam rotates according to the predetermined position of the signal device on the contact down or release. The corresponding output “on” and “off” electrical signal shows the opening and closing state of the butterfly valve. The grooved butterfly valve is divided into two types: handle grooved butterfly valve and worm-gear grooved butterfly valve.

Advantages of grooved butterfly valve!
1. Fast
Adopt groove clamp contact and corresponding pipe fitting placement pipeline, no need to weld and secondary placement, improve the placement rate.
2. Light
Clamp contact light weight, fewer bolts, convenient placement.
3. Reliable
C type rubber sealing ring, realize triple sealing, ensure the reliability of connected sealing.
4. Strong security
With the groove clamp contact and corresponding pipe fitting placement. It only needs to be mechanically assembled, no welding, no bright fire. Therefore, there is no welding slag and no turbified pipeline, can ensure the safety of the site. It is suitable for fire prohibition conditions.
5. Convenient installation
Due to the fast resettlement and the low repairs of resettlement, the comprehensive placement cost can be reduced by 30-50% compared with the flange.
6. Small occupation space
The groove clamp connection occupies about 70% of the space of the flange, and because the number of fastening bolts is small, it is especially suitable for the construction under the condition of narrow practical space.
Case:
Application:
Fire grooved end butterfly valves are commonly used in fire protection systems where reliable and fast-acting flow control is required in case of fire emergencies. These valves are designed with grooved ends that allow for quick and easy installation and removal. Some of the common applications of fire grooved end butterfly valves include:
1. Fire Protection Systems:
Fire grooved end butterfly valves are widely used in fire protection systems for controlling the flow of water and other fire suppression agents. They are commonly used in applications such as fire sprinkler systems, standpipes, and fire hydrants.
2. HVAC Systems:
Fire grooved end butterfly valves are used in heating, ventilation, and air conditioning (HVAC) systems for controlling air and water flow. They are commonly used in applications such as cooling towers, air handling units, and heat exchangers.
3. Water Treatment Systems:
Fire grooved end butterfly valves are used in water treatment systems to control water flow and other fluids. They are commonly used in applications such as water distribution systems, water treatment plants, and pumping stations.
4. Industrial Applications:
Fire grooved end butterfly valves are widely used in various industrial applications requiring reliable and fast-acting flow control. They are used in applications such as chemical processing plants, oil and gas refineries, and power generation facilities.
