| Pneumatic Control Valves |
| SUNGO鈥檚 ZMA/BP Pneumatic diaphragm single seat control valve has adopted top-guided structure. Compact body structure, S-streamline liquid channel can supply big flow coefficient, wider rangeability and more precise flow characteristic. It has aseismatic and wearable characteristic because of big guided square in the core鈥檚 guided part. The seat closed performance was processed as per GB/T4213-92,ANSI,DIN standard and it matched a multi-spring diaphragm actuator structure, which is fit for the situation of top reliability, high/low temperature in good closed performance and small differential pressure. |
