Integrated Flanged Type Tilting Disc Check Valve

No Leakage Risk Guaranteed, Ideal for High-risk & High-pressure EnvironmentsSplit-body Design Limitation: Its flange and valve body are manufactured separately and connected via bolts. Under high-pressure, high-temperature, or severe thermal cycling conditions, the joint face becomes a potential leakage point, and the sealing gasket is prone to aging.One-piece/Integrated Design Advantage: The valve body and connecting flange are integrally formed in a single piece, fundamentally eliminating the primary leakage path between the main valve body and the pipeline. This is critical for pipeline systems transporting toxic, flammable, explosive, or high-purity media (e.g., hydrogen, ethylene, chemicals), making it the inevitable choice for applications demanding absolute safety.

Superior Structural Strength & Fatigue ResistanceThe integrally cast/forged structure enables it to withstand higher pipeline stress, water hammer impact, and mechanical vibration, with no risk of bolt connection fatigue failure. This advantage is particularly prominent in Class 600 and above high-pressure classes, large-diameter (DN300+) pipelines, or high-vibration environments such as offshore platforms, significantly extending the valve service life.

Ultimate Optimization of Flow Path PerformanceThe one-piece structure allows for a perfectly smooth transition between the internal valve flow path and the flange port during the design phase, eliminating any steps or cavities caused by connections and minimizing the fluid resistance coefficient. This maximizes the "low flow resistance" advantage of the swash plate check valve, delivering superior long-term energy-saving benefits especially in high-energy-consumption pumping systems.

Maintenance Cost & Long-term EconomyAlthough the initial procurement cost is generally higher, the one-piece/integrated design offers lifetime maintenance-free operation (no need to worry about flange connection loosening or gasket replacement), boasts ultra-high reliability, and requires almost no downtime for inspection and repair. From the perspective of the total cost throughout the equipment's lifecycle, the one-piece design is often more economical.
