Coliter®’s soft sealing gate valves deliver bubble-tight shut-off in water supply, HVAC, and municipal pipelines with zero leakage and low torque operation. The series includes the Z41X rising stem type, Z45X non-rising stem type, compact Z15X threaded-end model, and secure DZ45X/DZ15X lockable variants—all featuring a resilient rubber or EPDM wedge that seals against a precision-machined brass or ductile iron seat. Rated at PN16 (1.6 MPa) and suitable for temperatures up to 80°C, these valves comply with GB/T 12234 and offer full-port flow with minimal pressure drop. Ideal for building mains, pump stations, and irrigation networks where reliable isolation and long service life are critical.
