How to determine the compatibility of NORGREN products with my existing pneumatic system?

First, check the key parameters of your existing system, including working pressure range, air flow rate, interface size (e.g., G1/2, NPT1/4), and voltage type (AC/DC, voltage value). Then compare these parameters with the product's technical specifications provided in the NORGREN official manual. It is recommended to consult the manufacturer's technical support team for confirmation if there is any uncertainty.

What are the main factors affecting the service life of NORGREN pneumatic valves?

The main factors include: 1. Cleanliness of the compressed air (impurities can cause internal wear); 2. Stability of the working pressure (excessive pressure or pressure fluctuations accelerate component fatigue); 3. Working environment (temperature, humidity, chemical corrosion); 4. Frequency of use (high-frequency switching increases wear of moving parts); 5. Regular maintenance (lack of lubrication or delayed replacement of wearing parts shortens service life).

Can NORGREN products be used in high-temperature and high-humidity environments?

Yes, but it is necessary to select the appropriate model. For high-temperature environments (≤ 120℃), choose valves and actuators with fluorine rubber (FKM) seals and aluminum alloy bodies with anti-high-temperature coatings. For high-humidity environments, select products with IP65 or higher protection ratings, and ensure the compressed air is dried (dew point ≤ -20℃) to prevent internal corrosion. It is not recommended to use standard models in environments with temperature exceeding 120℃ or relative humidity exceeding 95% for a long time.
