Advantage Description

valve body

316L stainless steel (DIN 1.4435)

Resistant to chloride ion corrosion and stress cracking, suitable for seawater and acid-base media

sealing element

Viton ® (Fluororubber)

EPDM, FFKM (Perfluoroether)

Resistant to oil, high temperature, and chemical corrosion, with a lifespan of over 5 years

Sensing membrane

Welded 316L isolation membrane

Gold plated film (H ₂ special), ceramic film

Anti medium penetration, compatible with hydrogen and highly corrosive fluids

Filling fluid
