🔍 Key Concepts

• Identify whether the stem moves up and down with the handwheel (rising stem) or only turns in place (non-rising stem). • Consider what type of valve this appears to be based on the internal shape and flow path (e.g., gate vs. globe and which is normally used for throttling). • Look closely at how the seat and disc are arranged and whether they could be removed for repair or replacement.

💭 Think About

• From the illustration, what happens to the stem position relative to the valve body when you would turn the handwheel—does the threaded portion travel vertically or stay inside the bonnet? • Does this valve’s internal passageway look suited to quick full-open/close service or to gradual control of flow? How does that affect whether it’s normally used for throttling? • Can you see separate seat pieces threaded or fitted into the body, or does the seat appear to be an integral, non-removable part of the casting?

✅ Before You Answer

• Verify whether the stem is visibly projecting further out of the valve as it moves—this indicates a rising stem rather than a non-rising design. • Check whether the flow passage is straight-through or forced to change direction, as in a globe-type valve commonly associated with throttling service. • Confirm if there are distinct seat rings or threaded interfaces that would allow seat maintenance or replacement, rather than assuming they cannot be repaired.
