SLV
GB Globe Valve
The SLV GB Globe Valve is a flanged globe valve designed and tested to Chinese GB national standards, serving flow regulation and throttling duties in general industrial, water and steam pipelines. Hard-alloy welded seat faces and flexible graphite packing make it a dependable workhorse across a broad temperature span.
Product Benefits
- Regulates and shuts off: As a globe pattern, it regulates flow smoothly and shuts off positively, which makes it more versatile than a plain isolation valve on lines that need adjustment.
- Hard-alloy seat faces: The seat sealing face is butt-welded with iron-base alloy or Stellite™ cobalt alloy.
- Resists throttling wear: That gives it far better resistance to throttling wear than a soft or unhardened seat.
- Full GB standards trail: Design, face-to-face dimensions, flanges, testing and marking all follow GB, which makes it straightforward to specify, inspect and replace like-for-like in plants built around GB piping practice.
Where It's Used
- Water, steam, industrial fluids: Typical services are water, steam and general industrial fluids in utility and process pipelines.
- Wide temperature span: It covers ambient duties down to sub-zero and up to hot steam conditions within its rating.
- GB-standard piping: It is a common sight on boiler houses, heating networks and factory service lines wherever GB-standard flanged piping is installed.
Good to Know
- Material range: Body and trim are offered in carbon steel, austenitic stainless grades and a chrome-moly alloy option, so the same pattern covers general, corrosive and hotter services.
- Graphite packing: Packing is enhanced flexible graphite, a robust choice for steam that also tolerates temperature swings well.
- Select for medium and heat: Choose the body material to match both the medium and the temperature.
- Mind the flow direction: Globe valves are directional: install them with flow as marked on the body.
- Seats can be re-lapped: Hard-faced seats can be re-lapped during overhaul, which extends the valve's economic life considerably.
