(API 624 Additional High Temperature Version)
Key Specifications / Features
The Bellows Sealed Gate Valve from our supplier is a high-quality valve designed for reliable and leak-free operation in industrial applications. It complies with the DIN 3352 standard and features a robust ASTM A351 CF3 cast stainless steel body, ensuring excellent corrosion resistance and durability. The wedge is made from ASTM A182 F316Ti, enhancing the valve's strength and reliability. With a DN80 (3-inch) size and a rating of PN40 (Class 300 LB), it is capable of handling significant pressure and flow. The valve is equipped with RF (Raised Face) flanged ends for secure and leak-free connections.
