Can the DIN 32676-A sanitary valve with TRICLOVER fittings, stainless steel AISI 304 be steam sterilized at +120°C for short cycles without damaging the VMQ (silicone) seal?

Yes — the DIN 32676-A sanitary valve with TRICLOVER fittings, stainless steel AISI 304 can be steam sterilized at +120°C for short cycles without damaging the VMQ (silicone) seal. The product specification explicitly states a standard operating range of -20°C to +100°C with the option for short steam sterilization up to +120°C. The VMQ seal is PZH-certified and designed for hygienic industry use, so occasional brief exposure to 120°C steam is within the allowed conditions. Limitations and recommendations: - Limit sterilization to short cycles only (as specified); repeated or prolonged exposure above +100°C may reduce seal life. - After steam sterilization, inspect the seal periodically for wear, hardening or compression set when used frequently at the upper temperature limit. - Follow manufacturer cleaning instructions (mild acidic/alkaline solutions up to +70°C) and avoid aggressive chemicals or sustained high temperatures to preserve seal performance.

Is the DIN 32676-A sanitary valve with TRICLOVER fittings, stainless steel AISI 304 compatible with cleaning using mild acidic or alkaline solutions up to +70°C without seal degradation?

Yes. The DIN 32676-A sanitary valve with TRICLOVER fittings, stainless steel AISI 304 is compatible with cleaning using mild acidic or alkaline solutions up to +70°C without seal degradation. The valve is specified for cleaning with mild acidic or alkaline solutions up to +70°C and is fitted with a VMQ (silicone) seal certified by PZH, designed for hygienic applications and the stated temperature range. Ensure cleaning agents are within “mild” concentration limits recommended by the chemical supplier and follow recommended contact times to preserve seal life.
