Product Advantage
The triple offset design ensures that the disc is away from the seat at a certain angle, thus reducing friction and wear during operation.
WCB (Cast Carbon Steel) Valve Body: Made of WCB (A216) carbon steel, it has excellent mechanical strength, pressure resistance and durability.
Metal-to-metal seal: enables it to withstand high temperatures and ensure reliable sealing under extreme conditions.
Fireproof Design: The design complies with API 607 and API 6FA fireproof standards. In the event of a fire, the valve maintains a reliable seal to prevent the spread of hazardous media.
High temperature and high pressure resistance: Due to the sturdy structure and metal sealing system, the valve can withstand high temperatures and high pressures, making it suitable for steam, oil, gas and other high-energy systems.
Low torque operation: The triple offset design reduces the friction between the disc and the seat, requiring lower operating torque.
