Type 807 & 752 Exotic Alloy Valves


For more than 60 years, Type 807 and Type 752 valves have performed in some of the world’s most demanding applications. If your application requires critical control of liquid, gas or steam, your choice of control valves is one of the most important decisions
you will make. When it comes to specifying a control valve, the variables are complicated and exacting. That is why Research Control® Valves are available in a broad range of options—so we can design a truly engineered solution that matches your requirements.


Processing plants, research facilities, and government agencies worldwide rely on Research Control Valves for repeatable performance and durability. Built for applications 1 in. (25.4 mm) and under, our Types 807 and 752 control valves are integral components in systems ranging from petrochemical to pharmaceutical manufacturing. It is an ideal choice for additive injection or flow and pressure control.
