Metal Sealing And Soft Sealing Ball Valves

Hard sealing ball valves are suitable for water, steam, oil, coal, fiber, consistency & corrosive media, and with granular media with high temperature and high pressure conditions. There are two types of Metal sealing ball valve: floating ball type and fixed ball type.

Description

Welcome to purchase discount source metal sealing and soft sealing ball valves from our company, which is one of the best China metal sealing and soft sealing ball valves manufacturers and suppliers.

By the processing for different conditions, the maximum hardness of Metal sealing ball valves can up to HRC78 and with the sealing surface treatment of valve seat, the highest hardness can reach up to HRC72. Through the matching grinding of Ball and seat, the entire sealing areas of metal sealing ball valve are with precision grinding.

 

Hard sealing ball valves are suitable for water, steam, oil, coal, fiber, consistency & corrosive media, and with granular media with high temperature and high pressure conditions. There are two types of Metal sealing ball valve: floating ball type and fixed ball type. The metal seat ring is in contact with the ball surface, and the valve seat ring and the ball surface are sealed by the action of the spring load on the valve seat ring.

 

The hard seal of the ball valve is metal to metal sealing. Both the sealed ball and valve seat are metal. Machining accuracy and the process is more difficult than the soft sealing ball valve. Generally, the metal sealing ball valve is used in high pressure conditions, which is usually more than 35MPa. However, the Soft seal of ball valve is the seal between the metal and non-metallic, such as nylon, tetrafluoroethylene.

 

The soft sealing or hard sealing is about the material that we choose. The hard seal is with precision processing, which can ensure the accuracy matching of valve seat with the valve seat. Usually, the materials are stainless steel and copper. However, Soft seal is the seal material embedded in the valve seat, which is non-metallic material. Due to the certain flexibility of soft sealing material, the accuracy of the processing requirements are relatively lower than that of hard seal.

 

The soft sealing ball valve and hard sealing ball valve selection is mainly on the basis of media, temperature and pressure. Usually, the medium containing solid particles or with wear stuff or temperature is higher than 200 degrees, it is better to use hard seal ball valve; furthermore,  the valve is larger than DN50, and with valve torque consideration, the fixed type metal seal ball valve is a perfect choice. The seal level of both soft seal ball valve and hard seal ball valve can reach level 6.
