Stainless Steel Class 800 Globe Valve

‌Pressure and temperature‌

‌Pressure level‌: Complies with ‌ASME Class 800‌ (about ‌13.8 MPa‌), suitable for high-pressure conditions, and the test pressure can reach ‌20.7 MPa‌.
‌Temperature range‌: Stainless steel materials (such as 304, 316) are suitable for ‌-29℃~425℃‌, and special designs can be extended to ‌500℃‌.

‌Material and connection‌
‌Valve body material‌: Made of ‌A182 F304/F316 stainless steel, it has strong corrosion resistance and is suitable for media such as acid, alkali, and steam.
‌Connection method‌: Supports ‌socket welding (SW)‌, ‌threaded connection‌ (NPT/BSP) and ‌flange connection‌ (ANSI B16.5), meeting high sealing requirements‌.

Structure and performance features ‌

Core design ‌
‌Sealing structure ‌: ‌Bellows seal ‌: Some models adopt bellows design to achieve ‌zero leakage‌, suitable for toxic or high-purity media ‌. ‌Double seal ‌: Flexible graphite packing + valve disc cladding ‌Stellite alloy‌, taking into account high temperature wear resistance and low pressure sealing ‌. ‌Valve stem guide ‌: Fully guided valve disc design ensures accurate alignment between valve disc and valve seat, reducing wear on sealing surface ‌. ‌
Performance advantages ‌
‌High pressure resistance ‌: Compact forged valve body structure, 20%~30% lighter than cast steel valve, strong impact resistance ‌. ‌Low maintenance ‌: Rising stem external thread design (OS&Y) for easy on-site maintenance and packing replacement ‌. ‌Multi-flow design ‌: Y-type flow channel reduces flow resistance, pressure loss is only ‌40%‌ of traditional stop valve, and supports flow regulation ‌.
