What is the applicable temperature for hard sealed ball valves? Hard sealed ball valves are suitable for high temperature and high pressure media such as water, steam, petroleum, coal, fiber, viscous and corrosive media, as well as media with particles. Metal sealed ball valves have two structures: floating ball and fixed ball. The metal seat ring contacts the spherical surface, and a uniform spring load acts on the seat ring to form a seal between the seat ring and the spherical surface.

Hard sealed ball valves are suitable for situations where two positions are cut off or adjusted. The connection between the ball valve and the actuator adopts a direct connection method.

Electric metal sealed ball valves are mainly suitable for working conditions with temperatures above 250 degrees Celsius. Electric metal sealed ball valves are mainly divided into two sealing structures: one-way sealing and two-way sealing;

Unidirectional sealing: can only seal in the specified direction indicated by the ball valve;

Bidirectional sealing: capable of sealing in both directions; The structural forms of electric hard seal ball valves are divided into floating ball type and fixed ball type;

The connection forms include flange connection, welding connection, and threaded connection. The electric actuator is equipped with a built-in servo system and does not require a separate servo amplifier. It can be controlled by inputting a 4-20mA signal and a 220VAC/380V power supply.

Electric hard sealed ball valves have the advantages of simple wiring, compact structure, small size, light weight, low resistance, stable and reliable operation, etc.

Huawei hard sealed ball valves are manufactured strictly in accordance with national and industry standards, and pass inspection and pressure testing before leaving the factory. Regular specifications can be shipped on the same day.
