VALVE WITH COUNTERWEIGHT – CC SERIES
Price variability based on valve characteristics
Non-return valve with counterweight.
Operation based on fluid pressure: when the pressure exceeds a certain threshold, the valve opens, allowing the fluid to pass. If the pressure drops or the flow reverses direction, the valve automatically closes, preventing the fluid from returning.
This type of valve is used for DNs above 300. The valve closes delicately with the help of weights placed to the right of the valve. The weights apply a force to the disc allowing it to open.
Autonomous operation.
