Electric Valve FAQ
Q: What is the typical lifespan of an electric valve?
A: Our electric valves are designed for long-term operation with an average lifespan of 500,000 to 1,000,000 cycles depending on operating conditions. Proper maintenance and avoiding operation beyond rated specifications can significantly extend service life. The brass-bodied valves typically last 5-7 years in normal conditions, while stainless steel models can exceed 10 years.
Q: Can electric valves be used with corrosive fluids?
A: Yes, when properly specified. We offer special versions with PTFE seals and 316 stainless steel bodies that can handle most corrosive media including acids, alkalis, and saltwater. Always check chemical compatibility charts for your specific application and consider optional lining materials for highly aggressive fluids.
Installation Guidelines
- Ensure proper alignment with piping system
- Allow sufficient space for actuator maintenance
- Install in accessible locations for future service
- Follow torque specifications for mounting bolts
- Use proper gaskets or thread sealant
- Verify electrical connections match power supply
Performance Comparison

| Response Time | 2 seconds | 0.5 seconds |
| Power Consumption | 15W | 8W |
| Noise Level | 65 dB | 45 dB |
Electric Valve FAQ
Q: How do I select the right electric valve size for my application?
A: Proper sizing requires considering three main factors: flow rate requirements (expressed in GPM or m³/h), pressure drop across the valve (typically 1-5 PSI for optimal operation), and pipe diameter. Our engineers can assist with calculations based on your system parameters. Generally, the valve size should match your pipe diameter unless you have specific flow control requirements that warrant a different size.
Maintenance Recommendations
- Perform visual inspection every 6 months
- Test operation monthly for frequently used valves
- Clean filter screens annually
- Lubricate moving parts as specified
- Check electrical connections for corrosion
- Monitor for unusual noise or vibration

Electric Valve FAQ
Q: What's the difference between normally open and normally closed electric valves?
A: Normally open (NO) valves remain open when de-energized and close when powered, while normally closed (NC) valves operate in the opposite manner. NO valves are preferred for fail-safe applications where flow must continue during power outages, while NC valves provide better security against leakage when not in active use. Selection depends on your system's safety and operational requirements.
