Iris ?? valves

Iris ?? valves

Iris ?? valves

(OP)
Please can somebody tell me what the correct name is, and who manufactures/distributes valves that form a variable hexagonal orifice plate from sliding sheet steel plates? The valve works like a shutter on a camera, and I believe them to be called iris valves (not the iris diaphragm type). Any suggestion greatly appreciated, as I am starting to think they don’t exist and I dreamt the whole thing

RE: Iris ?? valves

I believe what you are thinking of is also called a variable diameter orifice valve? I vaguely remember a manufacturer named Vortex or something similar to Vortex.

RE: Iris ?? valves

(OP)
the company you are thinking of is Salina Vortex in Kansas
Phone number is 785-825-7177 or fax 785-825-7194

RE: Iris ?? valves

(OP)
Iris valves are not a metal interior valve. They use a nylon or other fabric sleeve. As you pull the lever on the outside of the valve, the sleeve twists and the opening closes. They are commonly used for controlling the flow of plastic pellets and other solids.

RE: Iris ?? valves

www.mucon.com is the website for the company that make the Iris valve.
