Selection Guide

The primary purpose of a LACT system is to measure and transfer process fluid from one location to another.  Valin produces LACT systems for 3 basic applications: a pipeline LACT, a truck loading LACT, and a truck unloading LACT.  The table below gives examples of each.  Valin also manufactures for applications other than those identified below.

Application Supply (Inlet) Delivery (Outlet)
Pipeline LACT Storage Tank Pipeline
Truck Loading LACT Storage Tank Truck or Rail Car
Truck Unloading LACT Truck Storage Tank
Combination Pipeline & Truck Loading LACT Storage Tank Pipeline, Truck or Rail Car
