Metal Seated Ball Valve for High-temperature Service

Metal-seated ball valves incorporate a metal-to-metal seal between the seats and ball of the valve assembly. Our high-temperature metal-seated ball valves are engineered, constructed, and tested with careful metallurgical selection of all valve parts, using special surface finishing and treatments, hard coatings, and thorough analyses of mechanical strength and thermal expansion, ensure that our high-temperature metal-seated ball valves are a proven choice for the industries' toughest and most demanding applications.

Fire-safe is guaranteed without exception

Metal or hard graphite seats are resistant to great heat, while flexible graphite is used for other sealing components like gland packing and flange gaskets to ensure that no part of the valve is damaged by high temperatures. In addition, since electric current can flow between the components, an anti-static device is unnecessary.

Metal Seated Ball Valve for Abrasion Resistance

The metal-to-metal seat ball valve is designed for abrasive and erosion service and is equipped with a specially designed scraper design seat and high hardness material.

The valve ball and seat of the ball valve are made of very hard material and are not easily damaged by the service fluid.

Bidirectional sealing and the scraper seat design enable the metal-to-metal seat ball valve to maintain the sealing and long-term operation.

These are to prevent damage from service fluid and erosion from inside passage.

Shut off class:    BS-EN 12266-1 Rate A, FCI 70-2Class V (Rate B, Class VI upon request),  or Zero  Leakage.
