Coliter ® Magnetic Lockable Gate Valve – Lead-Free, PN16, WRAS Certified
ZF1012 Magnetic Lockable Gate Valve – Tamper-Resistant Shut-Off with Refined Key Access
The Coliter® ZF1012 Magnetic Lockable Gate Valve is a secure, lead-free brass gate valve engineered to prevent unauthorized operation in residential water meter leads, building service lines, and municipal utility networks. It incorporates an advanced magnetic locking system that requires a proprietary magnetic key tool for actuation—ensuring tamper resistance without external locks, caps, or visible mechanisms. Built from forged HPb59-1 or CW617N brass with a resilient rubber wedge seal, it delivers bubble-tight shut-off and full-port flow for minimal pressure loss. Certified to WRAS, ACS, and GB/T 17241 standards for potable water safety, the ZF1012 operates at PN16 (1.6 MPa) within a temperature range of 0°C to 90°C. Available in sizes DN15–DN50 with ISO 228 (BSP) threads, it offers reliable, maintenance-free performance for water authorities and facility managers seeking secure infrastructure control.
