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. 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. 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.
