Common materials include stainless steel, carbon steel, and brass. The choice depends on the application's environmental conditions and fluid compatibility. Stainless steel (e.g., 316) offers high corrosion resistance, while brass is suitable for lower-pressure applications.
Nominal size determines flow capacity and mating compatibility. It should match the hose or pipe size in your system. Refer to the manufacturer's specifications and standards like ISO 7241-1 to ensure proper fit and performance.
The operating pressure range is 1.0–1.6 MPa. However, this is a reference range; the actual maximum pressure depends on the specific model and material. Always verify with the manufacturer for your application.
The standard temperature range is -20 to 100°C, but this depends on the seal material. NBR seals are suitable for mineral oils within this range, while FKM seals may be required for higher temperatures. Confirm the seal material and temperature limits with the supplier.
