Pertanyaan yang Sering Diajukan
Pertanyaan umum tentang ASAHI dari 3G Electric.
What materials are ASAHI valves typically made from?
ASAHI manufactures valves primarily from PVC, CPVC, PVDF, and polypropylene. PVC is common for general-purpose water and chemical applications, while CPVC offers higher temperature resistance up to 200°F. PVDF is used for aggressive chemicals and high-purity processes. Polypropylene is employed in some gate valve wedges. Material selection depends on the fluid type, temperature, and pressure requirements.
What is the maximum pressure rating for ASAHI PVC ball valves?
ASAHI PVC ball valves are typically rated for a maximum cold working pressure (CWP) of 150 psi. This rating applies to standard manual two-way ball valves in sizes up to 4 inches. Pressure ratings may vary with temperature; derating factors apply at elevated temperatures. Always consult the specific product datasheet for exact limits.
Are ASAHI electrically actuated ball valves available with manual override?
Yes, ASAHI electrically actuated ball valves, such as the 1-inch PVC model (MPN 16107130010), include a manual override feature. This allows the valve to be operated manually in the event of power loss or during maintenance. The actuator operates on 95 to 265V AC and is designed for remote or automated control.
What types of connections do ASAHI valves offer?
ASAHI valves are available with socket, threaded (MNPT/FNPT), flanged (Class 150), and union end connections. Socket connections are common for solvent welding in PVC/CPVC systems. Flanged connections are used for larger sizes like 6-inch gate valves. Threaded ends are typical for smaller ball valves. The specific connection type depends on the valve model and application.
Can ASAHI diaphragm valves be used for chemical applications?
Yes, ASAHI diaphragm valves, such as the 1-inch PVDF model with PTFE diaphragm (MPN 1544010), are designed for chemical applications. The PVDF body provides corrosion resistance to many acids, bases, and solvents, while the PTFE diaphragm offers chemical inertness and a bubble-tight seal. These valves are rated for 150 psi CWP and are suitable for aggressive media handling.
What sizes of ASAHI Y-strainer screens does 3G Electric supply?
3G Electric supplies replacement Y-strainer screens for ASAHI strainers in mesh sizes such as 0.0331 inches and 0.0165 inches. These screens are made of PVC and are designed to fit specific ASAHI Y-strainer models. They are used for filtering particulates from fluids in piping systems. Other mesh sizes may be available upon request.
