Metal Seated Ball Valve is manufactured for high temperature up to 540℃ (may be higher based on the material of body and trim) or abrasion resistance. Our Metal Seated Ball Valves are Zero leakage (bubble tight seal). Metal Seated Ball Valve is also called metal to metal ball valve, as the seat and ball are made from metal.
For metal seated ball valve, the seat ring and ball are precisely machined, coated by high velocity oxygen fuel (HVOF) coating process and lapped to match ball, creating a positive seal for bubble-tight performance. Our Metal seated trunnion ball valves have many advantages such as excellent corrosion & wear resistance, tight shut-off, smooth control, low torque, wide temperature & pressure range, as well as stability under pressure. Metal seated ball valve provide long service life with outstanding fugitive emissions performance and low operating torques in even the toughest applications.

Zero Leak Metal Seated Ball Valve

The sealing between the seat and body is O-ring. It is designed for temperature below 150˚C and zero leakage warranty. This design is mainly for gas compression project.

Leakage Rate

Zero leakage available (MUCH higher level than ANSI/FCI 70-2 Class V shut-off, Class VI).

Types: Metal seated trunnion ball valves and metal seated floating ball valves.

Metal Seated Trunnion Mounted Ball Valves are split-body. Trunnion mounted ball valve are with spring-loaded seats with cavity relief; they are double block-and-bleed capability.
Metal seated floating ball valve is with Zero leakage for hightemperature operating conditions. Furthermore, seats with hard surface materials in Chromium Carbide, Tungsten Carbide or Stellite are also available. All floating ball valve are Antistatic Design and Automatic Body Cavity Relief.
Metal seated floating ball valve series includes a specific model for highly abrasive catalyst services or with the presence of solids, called SAT3.

Features & Benefits

a) Unique, the metal seated ball valve with patented single-seat ball valve design. It has a flat spring set acting through a hard-faced bearing against the bottom ball shaft which provides sufficient initial ball-seat load for valve tightness, even at low delta P.
b) Metal seated ball valve proven in qualification tests and field operation to be solids–proof, even for the toughest applications on slurry service with solids particles.
c) Tightness rates: Allowable leakage rate at full Delta P: ASME/ FCI 70-2 Class VI/V. Tighter shutoff available upon request.
The leakage rate also can be customization from end-user request
d) The metal seated ball valve with standard extension bonnet/stem, whose design base on the different temperature range.
e) Uni-directional or bi-directional sealing

To ensure product reliability, our ball valve designs are validated by actual prototype testing that includes a high cycle testing. The valves are produced by employing state-of-the-art manufacturing technology and under strict quality control standards.
