2.1 Rising-Stem Valves - NRC Home Page

movement of the valve stem.The most common rising-stem valve designs are gate valves and globe valves.2.1.1 Gate Valves .Gate valves are used to start or stop flow,but are not intended to regulate or throttle flow.The name [email protected] comes from the appearance of the disc in the flow stream.Figure 2-2 shows a common rising-stem gate valve design.All You Need To Know About Gate Valve - NTGD ValveRising stem Gate Valve The valves stem nut is on the valve bonnet or bracket.It will rotate to lift (open the gate) and lowering (close the gate) of the valve stem.This type of design is widely used because the valve stem lead screw can be lubricated,and the degree of opening and closing of the gate is distinct.Cameron ORBIT Rising Stem Ball ValvesORBIT rising stem ball valve incorporate a proven tilt-and-turn operation that eliminates seal rubbing,which is the primary cause of valve failure.The absence of seal rubbing during both opening and closing means easy,low-torque valve operation and long-term reliable performance.
