The Z41H forged steel flange gate valve is the most widely used valve. Its popularity is due to the low friction between the sealing surfaces during the opening and closing process, which is relatively durable, has a small opening height, is easy to manufacture, and is convenient to maintain. Not only suitable for medium and low pressure, but also suitable for high pressure. Its closing principle is to rely on the pressure of the valve stem to make the sealing surface of the disc and the sealing surface of the valve seat closely fit to prevent the medium from flowing.

Z41H flange forged steel gate valve is suitable for Class150 ~ 2500, working temperature -29 ~ 425 ℃ (carbon steel) or -29 ~ 500 ℃ (stainless steel) small diameter pipeline, used to cut off or connect the medium in the pipeline, Different materials are selected, which can be applied to various media such as water, steam, oil, nitric acid, acetic acid, oxidizing medium, urea, etc.

Features of Z41H flange forged steel gate valve:

1. The gate valve has reasonable structural design, reliable sealing, smooth passage and small flow resistance coefficient.

2. The sealing surface of the gate and valve seat is made of iron-based alloy surfacing or stellite cobalt-based cemented carbide, which is wear-resistant, high temperature resistant, corrosion resistant, scratch resistant, long service life, open and close The external force required is small.

3. It adopts wedge-type elastic gate or rigid wedge-type single gate structure, medium and large diameters are equipped with rolling bearings, the switch is flexible, the opening and closing is easy, and the flow direction of the medium is not restricted.

4. After quenching and tempering and surface nitriding treatment, the valve stem has good corrosion resistance, scratch resistance and wear resistance. Various piping flange standards and flange sealing surface types can be used to meet various engineering needs and user requirements. When fully open, the sealing surface is less eroded by the working medium than the stop valve.

5. The valve body has a complete range of materials, and the packing and gasket can be reasonably selected according to actual working conditions or user requirements, which can be suitable for various pressure, temperature and medium working conditions. The body shape is relatively simple, and the casting process is better.

Forged steel valves are mainly used in the pipelines of various systems in thermal power plants to cut off or connect pipeline media. Applicable medium: non-corrosive medium such as water and steam. Compared with other valve products, forged steel valves are characterized by high temperature and high pressure, unique self-sealing design, the higher the pressure, the more reliable the sealing. Due to the special performance, technical characteristics and working conditions, the product has also become a substitute for other products.

The products adopt ISO, API, ANSI, BS, DIN, NF, JIS, JPI, GB, JB and other advanced domestic and foreign standards. The product diameter is 3/8"-2" (DN10mm-50mm), and the pressure rating is 150Lb- 2500Lb (0.1Mpa-42.0Mpa), working temperature is -196℃-680℃.
