Coliter® offers a complete range of pressure reducing valves (PRVs) to stabilize downstream water pressure in residential, commercial, and municipal pipelines. Our series includes the JY1001 brass direct-acting PRV—ideal for homes and small buildings with compact installation—and the JY200X pilot-operated PRV made of epoxy-coated ductile iron for high-flow, high-stability applications like high-rise buildings and district networks. Both types maintain constant outlet pressure despite inlet fluctuations, feature adjustable set points, optional pressure gauges, and comply with GB/T 22130 standards. Designed for silent operation, corrosion resistance, and long service life—backed by ISO-certified manufacturing and global OEM support.
