PPH Flanged Diaphragm Self-operated Pressure Reducing Valve, PPH Plastic Acid Alkali & High Temperature Resistant Liquid Pipeline Pressure Stabilizing Reducing Valve

PPH flanged diaphragm self-operated pressure reducing valve adopts PPH (polypropylene homopolymer) engineering plastic body, flanged connection, diaphragm feedback structure. It automatically adjusts spool opening according to downstream pressure feedback to reduce and stabilize outlet pressure without external air or power supply. Compared with UPVC, it has better high-temperature resistance, acid and alkali resistance. Suitable for hot water and acid-base chemicals, protecting downstream pipelines and instruments from high pressure impact. Outlet pressure can be adjusted on the top.
