Inside the W&G Global Saver.
Explore the internal engineering, multi-stage pressure equalization chambers, and aerospace-grade brass tolerances that purge compressed air from your water line.
Initializing 3D photogrammetry...
Engineered from the inside out.
Every single fitting, tolerance, and polymer barrier is precision-manufactured to purge air locks without impeding downstream volume. Explore the disassembled optical anatomy below.
High-Visibility Butterfly Actuator
Impact-resistant polymer lever with calibrated quarter-turn stroke for instantaneous isolation and smooth torque management.
Forged Brass Pressure Casing
Solid CW617N European brass body precision-machined to withstand high-pressure water hammer up to 16 Bar without micro-fracturing.
Air Purge Dynamic Core
Mirror-polished spherical core and virgin PTFE seating rings that isolate compressed air locks and ensure zero-drag laminar flow.
Dual-Seal Compression Rings
Precision push-fit collars, heavy-duty brass union nuts, and triple-retained elastomer gaskets engineered for 25+ years of zero-leak service.
Industrial Grade Reliability
Engineered to meet British water regulations and European plumbing directives. Fits standard domestic and light-commercial meter inlets.
