Frequently Asked Questions:
-
Q: Why choose 316 stainless steel for marine applications?
A: SS316 contains molybdenum (2-3%) which significantly improves resistance to chloride-induced corrosion compared to 304 stainless steel, making it ideal for seawater systems. -
Q: Can this valve handle high-viscosity fluids?
A: Yes, the full-bore design and PTFE seals accommodate fluids up to 600 cSt viscosity. For higher viscosities, special seat materials can be specified. -
Q: Are different flange face types available?
A: Standard supply includes RF (Raised Face) flanges. FF (Flat Face) and RTJ (Ring Type Joint) configurations are available upon request. -
Q: What maintenance is required?
A: These valves are designed for minimal maintenance. Periodic lubrication of the stem (annually) and visual inspection of seals (every 3-5 years) is recommended. -
Q: Is locking capability available?
A: Yes, we offer lever handles with padlock provisions to prevent unauthorized operation in critical processes. -
Q: Can you provide actuated versions?
A: Electric, pneumatic, and hydraulic actuators can be mounted with ISO 5211 adapter pads. Please specify torque requirements. -
Q: What is the lead time for DN80 valves?
A: Standard sizes (DN15-DN100) ship within 30 days. Larger sizes may require 45-60 days. Expedited production is available. -
Q: Do you provide test reports?
A> All valves include factory test certificates per EN 12266-1 standards. Third-party inspection and certification available upon request.
