The PRH series ultra pure high flow pressure reducing valve adopts a single-stage diaphragm hard sealing design, with ultra-low leakage rate, internal EP electrolytic polishing treatment, and ultra-low internal surface roughness. High voltage input

(Up to 3500Psi), meeting high flow requirements for low voltage output. High purity gas suitable for use in the semiconductor industry. Each pressure reducing valve undergoes separate pressure testing, helium mass spectrometry leak testing, and particulate matter detection before leaving the factory.
