- What are Valves?
- Valves control fluid flow in vessel piping systems for various services including seawater, freshwater, fuel, and hydraulic systems. Common types include Gate Valves (on; off service), Globe Valves (flow regulation), Ball Valves (quick shut-off), Butterfly Valves (large diameter; low pressure drop), and Check Valves (prevent backflow).
- What are the different types of Valves?
- Common types include Gate Valves, Globe Valves, Ball Valves, Butterfly Valves, Check Valves.
- What standards apply to Valves?
- Products in this category typically reference ISO 10434:2020 (Gate), ISO 17292:2015 (Ball), and EN 593:2017 (Butterfly). Specific requirements may vary by service and classification society.
- Buyer requirements
- Procurement typically requires Type, Size (DN), and Pressure Class (PN) to match piping system specifications. End Connection (Flanged; Threaded; Welded), Body Material (Bronze; Cast Iron; Steel; Stainless), and Trim/Seat Material are critical, as material must suit service (seawater typically requires bronze or stainless; fuel systems require compatible materials).
