Product Description

Summary
Our company’s range of filter‑regulators is specially designed and manufactured to meet the specific requirements of Chinese production environments, offering superior performance in terms of higher flow rates and precise stability. They are widely used in automated control systems, providing air‑source filtration and pressure reduction for electro‑pneumatic transducers, valve positioners, and various pneumatic instruments and actuators.
Features
① Exquisite craftsmanship, ingenious structure, and elegant appearance.
② Filtration is pure and equipped with a PE microporous filter element, which can be reused.
③ Aluminum alloy castings undergo anodizing and are finished with a powder-coated surface, offering robustness, aesthetic appeal, and excellent corrosion resistance.
④The material of the joint area is stainless steel.
⑤ Wastewater discharge is convenient and effective.
⑥ Can be delivered as an integrated unit with the factory’s electrical transducers and electrical valve positioners, offering convenient installation and a compact, aesthetically pleasing design.
