Material Definition Of Hastelloy Check Valves

Hastelloy là một hợp kim niken-molypden. Hợp kim này có hàm lượng carbon cực thấp và hàm lượng cao các nguyên tố Ni, Mo và Cr, thuộc nhóm vật liệu chống ăn mòn và chịu nhiệt độ cao.

Có nhiều loại Hastelloy khác nhau, trong đó phần lớn là các hợp kim niken-crom-molypden. Mỗi loại trong số này đều được tối ưu hóa cho một mục đích cụ thể, nhưng tất cả đều có khả năng chống ăn mòn rất cao.

Applications of Hastelloy Check Valve

In general, Hastelloy check valves are mainly applied for liquids, air, or gases. By the way, a Hastelloy check valve is only used to clean filtered or strained liquids or gases. To achieve the Hastelloy check valves clean from dirty, you can put a strainer with a good wire mesh at the head of the Hastelloy check valves. In addition, the valves are applied to serve for vacuum relief. The internal threads side of the valve is linked with the valve service.

Features of Hastelloy Check Valve

• A Hastelloy check valve is made of titanium or alloy 20 for the body, piston, spring as well as locknuts.
• The seal of Hastelloy check valves is tight with the soft material of PTFE.
• Hastelloy check valves are tamper-proof because they can not adjust or remove externally to alter the pressure set once all the systems settle down. You can adjust the pressure setting into a factory set under certain circumstances.
• To reach the goal of a different pressure range, spare springs are able to adjust in the field.

Operation of Hastelloy Check Valve

Although a Hastelloy check valve is designed for a specific cracking pressure in the factory, it can be set in the field by removing the check valve from the piping system. Operating the right cracking pressure needs some tries and measurements. You also need a pressure gauge to verify the pressure. To achieve an ideal pressure state, Hastelloy check valves remain unscrewed from the mounting place. A Hastelloy check valve can increase the crack pressure by removing the line.
