Precision Cast Hard Sealed Cast Steel Gate Valve

Our precision cast hard sealed cast steel gate valve uses cast steel as the main structure. Cast steel has high strength, high toughness, and good high temperature and high pressure resistance. It can withstand medium pressure and temperature changes under complex working conditions, ensuring long-term stable operation of the valve.

The flange connection makes it easy to install and disassemble the pipeline. The valve and the pipeline flange are tightly fixed by bolts to ensure a firm connection and reliable sealing. It can be adapted to pipeline systems with different pipe diameters and pressure levels. Its working principle is based on the vertical lifting movement of the gate. When the gate rises, the valve opens and the medium can pass smoothly; when the gate descends and fits tightly with the valve seat, the valve closes to cut off the flow of the medium, effectively ensuring the safe operation and process control of the pipeline system.

Advantages and features:

1. High pressure bearing capacity: The precision cast hard-sealed cast steel gate valve has excellent pressure bearing capacity due to the high strength characteristics of cast steel material. It can withstand higher working pressure. The nominal pressure range can usually reach PN1.0MPa - PN42.0MPa (Class150 - Class2500), which is suitable for high-pressure pipeline systems.

2. Good sealing performance: Through precise structural design and high-quality sealing materials, the cast steel flange gate valve achieves good sealing performance.

3. Easy and flexible operation: The precision cast hard-sealed cast steel gate valve has various and simple operation methods. When operated manually, the transmission structure design of the handwheel and the valve stem is reasonable, and the operating torque is moderate. The operator can easily open and close the valve.

4. Long service life: High-quality cast steel material, reasonable structural design and strict manufacturing process give the cast steel flange gate valve a long service life. Cast steel parts can effectively resist the erosion, wear and corrosion of the medium, reducing the frequency of maintenance and replacement due to material damage.

5. Wide applicability: Cast steel flange gate valves can adapt to a variety of media and complex working conditions, and can be used for the transportation of various media such as water, steam, air, oil, gas, acid and alkali solutions. In addition, the flange connection method makes it have good versatility and can be connected with various standard pipeline flanges. It is suitable for pipeline systems in multiple industries such as petroleum, chemical, electric power, metallurgy, and construction, and has broad application prospects.
