SLV
ANSI Globe Valve
The SLV ANSI Globe Valve is a flanged, ANSI-standard valve built for precise throttling and flow regulation rather than simple on/off duty. A rising stem shows valve position at a glance, and a renewable, hard-faced seat keeps it serviceable through years of process and steam work.
Product Benefits
- Superior flow control: Globe valves control flow far better than gate or butterfly types because the disc moves perpendicular to the seat, allowing fine, stable adjustment anywhere between open and closed.
- Position at a glance: The rising stem gives operators immediate visual confirmation of where the valve stands.
- Blow-out proof stem: The blow-out proof design adds a layer of safety on pressurized lines.
- Hard-faced seat: The seat sealing face is overlaid with a cobalt-base hard alloy, which resists the erosion and galling that throttling service inflicts on plain seats.
- Renewable sealing faces: Because the seat is renewable, the sealing surfaces can be restored rather than the whole valve replaced.
Where It's Used
- Regulation, not just isolation: It is a natural choice wherever flow must be regulated rather than just stopped.
- Steam and boiler lines: Typical duties include steam distribution, boiler feed and drain lines.
- ANSI/ASME plants: It also serves general process piping in plants built to ANSI/ASME standards.
- Frequent adjustment: Duties that call for constant trimming suit it particularly well, since the design tolerates repeated partial-open operation.
Good to Know
- Disc profile options: The standard disc is a plunger type, with ball, parabolic and flat disc options available.
- Match the flow characteristic: The disc profile changes the flow characteristic, so it is worth matching it to how finely you need to trim flow.
- Several pressure classes: Flanged ends in several pressure classes cover a wide range of line conditions.
- Higher pressure drop: Like all globe valves, it imposes a higher pressure drop than a straight-through valve because the flow path turns inside the body, and flow direction matters at installation.
- A worthwhile trade-off: Where the priority is control quality and a long-serviceable seat, that trade-off is usually well worth it.
