Metal Seated Ball Valve

Metal seated ball valve for severe services: high temperature, hight pressure and abrasive service; metal seated floating and trunnion mounted ball valves with zero leakage, meeting En 12266-1 rate A.
We have side entry and top entry metal seated ball valves. Metal seated ball valves are ideal for isolation purpose.
Our Metal seated ball valve have advantages, such as excellent corrosion & wear resistance, tight shut-off, smooth control, low torque, wide temperature & pressure range, as well as stability under pressure.
Hongar Valve is a metal seated ball valve manufacturer & supplier in China, with API 6D, API 607 and CE Certificate, providing best price metal seat ball valves.
The seat ring and ball are precisely machined and lapped to match ball, creating a positive seal for bubble-tight performance. Metal seated ball valve provides long service life with outstanding fugitive emissions performance and low operating torques in even the toughest applications.

Metal seated ball valve for high temperature

The split seat design (Part No. 5) for high temperature metal seated ball valve provides freedom for thermal expansion of the ball without jamming, even at extremely high temperatures.

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

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

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

Metal Seated Trunnion Mounted Ball Valves are split-body, trunnion-mounted ball valve 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 Relia 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.

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

Surface Coatings for Metal Seated Ball Valve

Unlike surface treatment methods whereby the existing surface is changed by diffusion, in surface coating an outer layer of new material is generated on the surface. The following types of surface coating methods are available in the Habonim metal seated range; chromium carbide with nickel chrome binder (Cr3C2), tungsten carbide with cobalt binder (WC-Co), and stellite welding.
