Coliter®’s hydraulic control valves are pilot-operated, multi-function automatic valves designed for intelligent water system management in high-rise buildings, fire protection, and municipal networks. The series includes the 600X electric hydraulic control valve (remote on/off via solenoid), 500X pressure relief/pressure reducing valve, 400X flow control valve, 300X slow-closing check valve, 200X pressure sustaining valve, and the LHS743X low-resistance backflow preventer. All models use system pressure as the driving force—requiring no external power—and feature brass or ductile iron bodies, Y-strainer integration, and precise pilot control for stable operation. Rated at PN16 (1.6 MPa) and suitable for temperatures up to 80°C, they ensure safe, energy-efficient, and code-compliant water distribution with automatic response to demand changes.
