What is a grooved butterfly valve？
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 the grooved butterfly valve：
Adopt groove clamp contact and corresponding pipe fitting placement pipeline, no need to weld and secondary placement, improve the placement rate.
Clamp contact light weight, fewer bolts, convenient placement.
C type rubber sealing ring, realize triple sealing, ensure the reliability of connected sealing.
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.
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.
