RTZ-8/1.7 (67CFSR) Type Filter Regulator

Industrial and Commercial/Boiler/Combustion Pressure Regulation Solutions

RTZ-8/1.7 (67CFSR) Type Filter Regulator

◉ Application

This pressure regulator is suitable for gas control systems in industries such as pharmaceutical and chemical engineering, and food and beverage manufacturing. It provides continuous pressure reduction for pneumatic controllers, electro-pneumatic controllers, and other instruments. Additional applications include pressure reduction for equipment like pneumatic chucks, air ejectors, and spray guns.

• Nominal Diameter (DN): DN 8×DN 8
  • Connection Type: NPT thread (Note: "NPT" = "National Pipe Thread Taper", a North American standard tapered thread designed for sealed pipe connections, which is critical for preventing gas leakage in precision industrial systems)

Supplementary Notes on Key Terms

1. Industry-specific Application Context:
   • In pharmaceutical/chemical industries, stable pressure supply is essential for precise process control (e.g., reagent delivery, reaction chamber gas regulation);
   • In food and beverage industries, the regulator’s material compatibility (implied by its use in clean production environments) and stable performance help avoid contamination or process fluctuations.
2. Pneumatic Equipment Terminology:
   • "Pneumatic chucks": Devices that use compressed air to clamp workpieces, common in automated machining;
   • "Air ejectors": Equipment that generates negative pressure via compressed air, used for suction or vacuum applications.
3. Wide Temperature Range (-40 °C ~ 82 °C): This range allows the regulator to operate in extreme low-temperature environments (e.g., cold storage auxiliary systems) and high-temperature industrial sites (e.g., near heat-generating equipment), expanding its applicability across diverse working conditions.
