C-Type
High precision electric stopper flow valve
The C-Type electric stopper valve improves enhance features of M-Type with higher velocity, closing force and extended anti-clogging features
Impact of C-Type electric stopper valve
- Utmost mold level stability through ultra fast response time
- Safe casting operation by 100% electric solution (no hydraulic)
- Smooth flow control through real in-line backlash-free and precise guiding
- Performance consistency all year long by heavy duty parts and design
- Ultra low maintenance requirements supported by RFID tracking solution
- Fast Return of Investment by thoroughly technology excellence
