Product features:
▶ Prevents misoperation of the handle
⊙ A 90° switch positioning tab with a keyhole is set up, which can be locked as needed to prevent misoperation. When the valve is opened, the handle is parallel to the pipe, and when the valve is closed, the handle is perpendicular to the pipe, which can ensure that the valve’s opening and closing instructions will not cause errors.
▶ Fireproof structure
⊙ The sealing surface of the valve adopts a metal sealing structure, the packing material is made of flexible graphite, and the gasket is made of stainless steel + flexible graphite structure. Therefore, the valve ensures a reliable seal even in fire situations.
▶ Anti-static structure
⊙ The metal parts such as the valve body, seat, and sphere of the high-performance metal hard seal ball valve are in close contact, naturally forming an electrostatic channel. Therefore, metal hard seal ball valves do not require a special anti-static device.
▶ Stem anti-flyout structure
⊙ The stem is designed with an anti-blow-out structure, which can ensure that the valve stem will not be blown out by the medium even in extreme cases such as abnormal pressure boost in the valve cavity and the failure of the packing platen. The valve stem adopts the design of the bottom-mounted structure with inverted seal, and the sealing force of the inverted seal increases with the increase of the medium pressure, so it can ensure the reliable sealing of the valve stem under various pressures.
▶ Medium flange quantitative compression design
▶ High-performance metal hard seal ball valve seat seal structure
⊙ High performance metal hard seal floating ball valve adopts ball rear seat sealing structure. Generally, one-way seals are used and the flow direction is marked on the valve body. If the user has special requirements, the two-way sealing structure can be adopted.
⊙ The valve seat is equipped with a dust-proof structure, compared with the ordinary ball valve seat structure, the valve seat structure design is combined with the special working conditions of polysilicon, and its targeted optimization design is optimized. The advantage of using an integral valve seat to hide the spring inside the valve seat is that it can effectively prevent powder (slag) from entering the spring cavity from the valve cavity and flow channel while ensuring the original function of the valve seat, causing the spring to fail.
▶ Valve seat scraper structure
⊙ Self-cleaning double scraper structure design: The inner and outer sides of the sealing surface of the valve seat are designed with a scraper structure, which can automatically clean the surface of the sphere when the valve switches and closes to ensure the sealing reliability and extend the service life of the valve.
▶ Prevent valves from rising and dying at high temperatures
▶ Uses advanced ball and seat hardening technology
⊙ Under high temperature conditions, the bulb and valve seat are easy to cause the rise and death of the ball and valve seat, resulting in the valve not being opened. The high-performance metal hard seal ball valve adopts a leaf spring or spring-loaded sealing structure, and the thermal expansion of parts can be absorbed by the leaf spring or spring at high temperature, so it can ensure that the valve will not rise and die at high temperature, and can be opened and closed flexibly.
