Is the 3-Way Normally Closed Switching Valve D3V suitable for continuous operation at temperatures between -20°C and +90°C?

Yes. The 3-Way Normally Closed Switching Valve D3V is suitable for continuous operation between -20°C and +90°C. Its specification states an operating temperature range of -20°C to +90°C, and its cast iron body, hardened steel stem and NBR sealing are engineered to maintain performance, tightness and durability across that temperature span.

Can the 3-Way Normally Closed Switching Valve D3V withstand exposure to hydraulic fluids other than standard mineral oil without seal degradation?

3-Way Normally Closed Switching Valve D3V: The valve uses high-quality NBR (nitrile) seals and is specified for operation with standard mineral oil within a temperature range of −20°C to +90°C. NBR offers good resistance to mineral oils, petroleum-based hydraulic fluids, and many common lubricants, so brief or limited exposure to similar petroleum-derived fluids typically will not cause immediate seal degradation. However, NBR has limited compatibility with certain hydraulic fluids: it is vulnerable to rapid swelling, hardening, or loss of elasticity when exposed long-term to phosphate esters, water-glycol fluids, some synthetic esters, ketones, chlorinated hydrocarbons, and strong aromatic solvents. Elevated temperatures and aggressive additives accelerate degradation. Recommendation: If you plan to use fluids other than standard mineral oil, confirm the specific fluid chemistry and operating temperature. For long-term use with non-petroleum or aggressive fluids, request compatibility data or consider valves with seals made of more chemically resistant elastomers (e.g., FKM/Viton, HNBR, or EPDM) to avoid premature seal failure.
