High pressure Valve Body

The valve body is a key component of the valve. As the outer shell of the valve's internal components such as the valve stem, valve disc and valve seat, it plays a vital role in ensuring the normal operation and sealing of the valve, and can effectively control the flow, pressure and flow direction of the fluid. MaterialCast iron: including gray cast iron and ductile iron. Gray cast iron is inexpensive and has a wide range of applications. It is suitable for low-pressure valves with an operating temperature between -15℃ and 200℃ and a nominal pressure of PN≤1.6MPa. It is often used in situations where water, steam, oil and gas are the media. Ductile iron has better mechanical properties than ordinary gray cast iron. It is suitable for medium and low-pressure valves with an operating temperature between -30℃ and 350℃ and a nominal pressure of PN≤4.0MPa. The applicable media are water, seawater, steam, air, gas, oil, etc. Carbon steel: Suitable for medium and high pressure valves w…
