Hard-Seal Weld Fitting for Critical Applications (-196℃～+500℃)

ASVK / ASV Straight Connector

Features
Metal-to-metal seal fittings are suitable for high-temperature, cryogenic, and applications where rubber or other non-metallic seals are not permitted. The spherical seal design ensures high reliability, low installation requirements, and extended service life.

Technical Data
● Fitting material: 304 stainless steel(-SS)，316L(-SL)
● Ball material: Stainless Steel 304
● Operating temperature:-196℃～+450℃(304 SS)，-196℃～+500℃(316L SL)
● Max. working pressure: Refer to table below. Note: Pressure rating decreases with increasing temperature (see Technical Data: Valve Material Properties page).
