Hard Seal Ball Valve Description
Hard seal ball valve is a kind of valve with metal sealing ring, its ball and seat are made of metal materials, through the rotation of the ball to achieve the opening and closing function. The core components include valve body, bonnet, ball, seat, stem, etc., and the sealing surface is metal-to-metal hard-to-contact
Commonly used materials
Valve body/valve cover: cast steel, carbon steel, forged steel, stainless steel.
Ball and seat: stainless steel (such as 1Cr13), high-strength alloy (surface hardened).
Seal ring: metal hard seal material (such as surfacing cemented carbide).

Metal seated ball valve
Advantages
Strong sealing performance: metal hard seal design can withstand extreme pressure and temperature, reducing the risk of leakage.
Resistant to high temperature and high pressure: Suitable for high temperature of 550℃ and high pressure of 42MPa.
Long life and low maintenance: metal sealing surface with low wear, long life and low maintenance cost.
Fire safety: Special fireproof structure maintains seal integrity at high temperatures and prevents fire leakage.
Multi-functional design: supports customised features such as anti-static structure and grease injection valve assisted sealing.
