Security Metering Valves

Willoughby security valves control water at lavatories, showers and toilets from the pipe chase, out of the user's reach. Choose PML and PSL pneumatic metering valve assemblies and E1L electronic valve assemblies in single (1) or dual (2) temperature, with machined stainless steel push buttons and escutcheons, piezo electronic buttons and ligature-resistant (PBH) buttons, plus T4 manual-reset and T4A auto-reset toilet overflow preventers. Willoughby lists the PML and E1L valves as lead-free. All are made by Willoughby Industries in Indianapolis, Indiana.
