Coliter® offers a complete range of lockable gate valves engineered to prevent unauthorized operation in residential, municipal, and utility applications.

All valves feature lead-free brass bodies, comply with WRAS, ACS, and GB/T 17241 standards for potable water, and support full-port flow with zero leakage. Available in DN15–DN25 with ISO 228 threads. Trusted by water authorities worldwide for tamper-proof performance and OEM flexibility.
