Plants and factories utilize process control devices to control the flow of fluids in processes, wherein

Heretofore, valves used in high-temperature, high-pressure processes were typically short-lived, often did not properly seal, and were expensive. Generally, these prior art valves were high-pressure s

Rotor means disposed in said flowpassage, bearing track means provided on said interior surface of said valve housing

One such means of limiting the rate of flow of fluid issuing from a fire hose is illustrated and described in U.S. Pat. No. 3,361,148. In this patent the globe valve which connects the hose to a water

Plants and factories utilize process control devices to control the flow of fluids in processes, wherein

A globe valve adapted for use at cryogenic temperatures having a valve seat in the valve body adapted to be closed by a conical seat disc. The seat disc is supported for vertical movement in a seat ho

One known arrangement utilizes two circular seats where the pressure forces cancel. These valves are relatively larger and more expensive than the standard gate and plug valves. Further, it is often d

Control systems and manual applications utilize various types of valves to turn fluid flows on and off, and also to modulate the rate of fluid flow through the valve. Fluid flow through a valve result
