Pertanyaan yang Sering Diajukan
Pertanyaan umum tentang HAM-LET dari 3G Electric.
What materials are used in HAM-LET needle valves?
HAM-LET needle valves, such as the H99 and H300U Series, are primarily constructed from 316 stainless steel for the valve body and bonnet. Stems are available in 316 stainless steel or 17-4PH stainless steel for enhanced wear resistance. Seals and packing materials vary by model, with PTFE and other polymers used for low-friction operation. The choice of material ensures compatibility with a wide range of liquid and gas media, including corrosive chemicals and high-purity fluids.
What is the Let-Lok connection system used in HAM-LET valves?
Let-Lok is HAM-LET's proprietary tube fitting system designed for leak-free connections in instrumentation and process lines. It uses a ferrule-based design that grips the tube without damaging it, allowing for repeated assembly and disassembly. Let-Lok connections are available on many HAM-LET needle valves, check valves, and ball valves, providing a reliable alternative to threaded or welded connections. They are compatible with standard metric and imperial tubing sizes.
Are HAM-LET ball valves suitable for three-way flow control?
Yes, HAM-LET offers three-way ball valves such as the H-6800 Series, which feature an L-flow pattern for diverting flow between ports. These valves are constructed from 316 stainless steel and are available with standard port ball ports. The wedge handle provides clear visual indication of the flow path. They are suitable for applications requiring flow switching or mixing in chemical, oil, and gas systems.
What standards do HAM-LET check valves comply with?
HAM-LET check valves, including the H-400 and H-410 Series, are designed to meet instrumentation-grade standards for leak-tightness and durability. They are typically rated for pressures up to 6000 psi (depending on size and connection type) and are compatible with media such as chemicals, gas, oil, and water. The poppet design ensures low cracking pressure and reliable backflow prevention. Specific models may comply with ISO 15848-1 for fugitive emission control.
Can HAM-LET diaphragm valves be used in high-purity applications?
Yes, HAM-LET high-purity diaphragm valves, such as the EVZS4R-BV, are designed for ultra-clean environments like semiconductor manufacturing and pharmaceutical processing. They feature 316L stainless steel bodies and chromium cobalt nickel diaphragms that minimize particle generation and chemical contamination. The manual actuation allows precise flow control, and the face seal connections ensure leak-free operation in critical gas and liquid systems.
Does 3G Electric supply HAM-LET products?
