Cast Iron gate valves are available in two basic types; non-rising stem Inside Screw and rising stem Outside Screw and Yoke type. The inside screw type has the stem actuating thread within the pressure envelope and is non-rising.This type of valve is usually used for non corrosive and reasonably clean services and has a smaller overall height than the outside screw type..


The outside screw, rising stem type has the stem actuating thread outside the pressure envelope and can be used on more active media where the fluid might otherwise have an adverse affect on the thread. Valve bodies are made from ductile iron or cast iron and have integral flanges. Seat rings are threaded and securely fixed into the body.
