Features
1、Strictly Adheres to National Standards, Reliable Design: The product's design and manufacturing comply with national standards such as GB/T 12235. Parameters like face-to-face dimensions and connection dimensions are highly standardized, offering strong versatility and meeting the needs of domestic projects in industries like petroleum, chemical, and power.
2、Low Fluid Resistance, Optimized Flow Path: The valve body adopts an integrally cast structure with a straight-through flow path, allowing smooth medium flow and low fluid resistance. The disc moves linearly up and down along the centerline of the fluid, offering flexible and reliable operation.
3、Reliable Sealing, Long Service Life: The sealing pair of the disc and seat features precision-lapped flat or tapered designs. During opening and closing, the sealing surfaces have no relative sliding, resulting in minimal wear and scratching, good sealing performance, and a long service life. Sealing surfaces can be combined with different materials to adapt to various operating conditions.
4、Easy Operation, Low Operating Torque: Rotating the handwheel drives the stem, utilizing threaded transmission for the stable lifting of the disc. Due to the absence of relative sliding on the sealing surfaces, frictional force during opening and closing is low, resulting in smaller operating torque and a smooth process.
5、Convenient Maintenance, Economical and Practical: The seat can be designed with a replaceable structure, facilitating the replacement of sealing elements during valve maintenance without removing the entire valve from the pipeline, significantly reducing maintenance costs and time. The body material is typically WCB cast steel, offering a robust structure and high cost-effectiveness.
6、Flange Connection, Easy Installation and Maintenance: Adopts a flange connection method, secured by bolts to the pipeline flange, offering a compact structure and convenient installation and maintenance. Connecting flange dimensions comply with standards such as GB/T 9113, providing broad universality and interchangeability. Drive modes include manual, gear transmission, electric, pneumatic, and other forms, meeting the requirements of different operating conditions.
