Water-sealed Valve FAQ
1. What makes a water-sealed valve different from standard valves?
A water-sealed valve uses a unique double-seal mechanism filled with water, providing superior leak resistance compared to traditional rubber or mechanical seals. The water layer acts as a barrier, preventing gas or fluid escape even under high pressure or temperature fluctuations.
2. How often should I maintain my water-sealed valve?
For optimal performance, we recommend inspecting your water-sealed valve every 6 months. The maintenance schedule depends on usage intensity and operating conditions. In normal residential applications, annual servicing is typically sufficient, while industrial systems may require quarterly checks.
3. Can the water-sealed valve handle corrosive fluids?
Yes, our water-sealed valves are available in corrosion-resistant materials like 316L stainless steel and PTFE-lined options specifically designed for aggressive chemicals. Always verify the material compatibility with your specific fluid before installation.
Installation Guidelines
- Ensure pipe surfaces are clean and free from debris before installation.
- Apply thread sealant or Teflon tape to male threads for NPT connections.
- Tighten connections using appropriate torque values (refer to installation manual).
- After installation, perform a pressure test at 1.5 times the working pressure for 30 minutes.
