As a specialized agent in fluid control solutions, Shanghai CAMP Environmental Protection Technology Co., Ltd. brings you our high-performance Double Eccentric Pneumatic Butterfly Valve designed specifically for water treatment facilities. Established in 2015, we've served clients across North America, South America, Eastern Europe, Southeast Asia, Africa, Oceania, Mid East, Eastern Asia, Western Europe, and other global markets from our Shanghai headquarters.
This engineered valve combines double eccentric design with pneumatic actuation to deliver exceptional shut-off capability in water and wastewater applications operating at 0.6-4.0MPa pressures. Its robust construction ensures reliable performance in critical treatment processes including:
- Pump discharge control
- Flow regulation in filtration systems
- Chemical dosing lines
- Sludge handling operations
Core Technical Advantages:
- Double eccentric design reduces seat wear by 80% compared to concentric valves
- Pneumatic actuators provide 5-second operation speed for rapid process control
- Bubble-tight shutoff meets AWWA standards
- Stem protection system prevents media contamination
Performance Specifications:
| Pressure Class | PN10-PN40 |
| Temperature Range | -10°C to 120°C |
| Flow Coefficient | Cv 580-22,500 |
| Leakage Class | ANSI Class VI |
The valve's corrosion-resistant components ensure 10+ years service life in aggressive water treatment environments. Optional accessories include:
- Positioners for precise flow modulation
- Limit switches for remote status indication
- Fail-safe mechanisms (spring return)
Frequently Asked Questions:
Q: How does double eccentric design benefit water treatment applications?
A: The offset stem position creates camming action that lifts the disc clear of the seat during operation, reducing friction and extending seal life in abrasive media.
Q: What pneumatic pressure is required for actuator operation?
A: Actuators function at standard 4-7 bar supply pressure with optional models available for low-pressure systems.
Q: Are these valves suitable for potable water systems?
A: Yes, with NSF-compliant seat materials available upon request.
Q: What maintenance intervals are recommended?
A: Our valves require only annual visual inspection and lubrication under normal operating conditions.
Q: Can you provide explosion-proof actuators?
A: ATEX-certified pneumatic actuators are available for hazardous area installations.
Q: What is the lead time for 24" valves?
A: Standard sizes ship in 3-4 weeks with expedited options available.
