Metal Seated Ball Valve is manufactured for high temperature up to 540¡æ (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 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.

SIZE RANGE AND PRESSURE CLASS

Size Range: 1/2 Inch to 10 Inch (DN15-DN250)
Pressure Range: Class 150 LB to 2500 LB (PN16-PN420)

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¨Cproof, 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 JSC metal seated range; chromium carbide with nickel chrome binder (Cr3C2), tungsten carbide with cobalt binder (WC-Co), and stellite welding.
