Description
3.1 Overview
The Model C Valve is designed to provide fully automatic, 3-way fluid
temperature control for diverting or mixing applications. Typical
applications include engine water jackets, lubricating oil cooling
systems, and mixing and diverting of fluids in process control and
industrial applications.
The thermostatic element (also referred to as ‘element’) in a Model C
Valve is fully enclosed and factory set, providing tamper-proof
operation. For maintenance, or to achieve a different set
temperature, the element can be changed, although this does require
removal of the valve from the adjoining pipework. Elements are
available with set temperatures from 18 to 113°C (65 to 235°F).
Valves are available in five sizes, and a variety of materials to suit
different fluids.
3.1.1 Manual override
Model C Valves do not have manual override capability.
3.2 Features
