Can the Mechanical Lever Pneumatic Diverter Valve with Tilt Roller, 5/2, Series 70 be used safely at temperatures below -10°C or above +60°C, and what precautions are required?

Mechanical Lever Pneumatic Diverter Valve with Tilt Roller, 5/2, Series 70 is specified to operate within a temperature range of -10°C to +60°C. Using it below -10°C or above +60°C is therefore outside the manufacturer’s rated limits and is not recommended without additional precautions. Risks of operating outside the range include seal hardening or leakage (NBR seals become rigid at low temperatures), lubricant thickening, altered material properties (plastics and nickel-plated/aluminum parts may become brittle or expand), slower or unreliable actuation, and potential loss of pressure rating or premature wear. Precautions if operation outside rated range is unavoidable: - Low temperatures ( +60°C): - Verify all materials (end cover plastic, seals, lubricants) are rated for higher temperatures; replace with high-temperature alternatives if available. - Provide thermal shielding or cooling and avoid direct exposure to heat sources. - Conduct high-temperature endurance testing to confirm performance and leak-tightness. - General: - Consult the manufacturer for approved modifications, alternative seal/lubricant options, and warranty implications. - Monitor the valve more frequently for leaks, wear, and performance changes if used outside spec. - Consider selecting a valve explicitly rated for the intended extreme temperature range for long-term safety and reliability.
