Description

Liquid Controls D4190 Pre-Set in Whole Gallon for 3 in. Meters The Liquid Controls D4190 Pre‑Set is a precision, manually programmable quantity control device designed to regulate whole‑gallon deliveries on 3‑inch Liquid Controls positive displacement meters. Built with a positive, non‑topping vernier clutch and a positive‑acting stop button, this two‑stage preset enables accurate control by counting down from a programmed quantity. When activated, it slows flow at the first knock‑off point and then shuts delivery at the final knock‑off by actuating a connected valve. Designed for reliability at speeds up to 250 RPM of the right‑hand wheel, the D4190 utilizes modern materials to deliver long‑term durability in demanding industrial environments. Compatible with all Liquid Controls meters and Veeder‑Root register mounts, it supports precise measurement in gallons, liters, dekaliters, barrels, and pounds across various unit increments. Combined with LC’s positive displacement meters and mechanical registers, the D4190 provides exceptional repeatability and linearity performance for high‑accuracy metering applications.
