Angle Valve
Glass angle valve, DN 15 to DN 50, 90° and 80°
Borosilicate glass angle valve combining a direction change and isolation in one body — DN 15 to DN 50, in 90° and 80° builds.
| Product type | Glass angle valve |
|---|---|
| Material | Borosilicate 3.3 |
| Spindle | PTFE |
| Nominal bore range | DN 15 to DN 50 |
| End connection | Beaded glass ends with backing flanges and PTFE-envelope gaskets |
| Flange drilling | See the drilling table — BS 10 Table E, BS 10 Table F and ASA drilling available |
| Pressure rating | Not published on the valve catalogue page — confirm with us for your duty |
| Temperature rating | Not published on the valve catalogue page — confirm with us for your duty |
Product overview
What it does, and where it fits.
An angle valve turns the line and shuts it off in a single component, which removes a bend, a joint and a length of pipe from the layout. On a glass line that matters twice over: fewer joints means fewer potential leak paths and less glass to support.
Read the D column carefully — on this table it is an angle in degrees, not a diameter. DN 15 and DN 25 are each listed twice, once at 90° and once at 80°, with identical dimensions otherwise. The 80° build is what gives a horizontal run a slight fall so it drains, exactly as the 80° bends in the pipeline range do.
Face-to-face is short for the bore — 50 mm at DN 15 and 150 mm at DN 50 — so the valve fits where a separate bend plus valve would not.
Features
Built into every unit.
- Direction change and isolation in one body
- Available in 90° and 80° at DN 15 and DN 25
- Short face to face: 50 mm at DN 15 to 150 mm at DN 50
- Borosilicate 3.3 body with PTFE spindle
- DN 15 to DN 50
Benefits
Why it earns its place in the line.
- Removes a bend, a joint and a pipe length from the layout
- The 80° build gives a run a fall to drain
- Fully transparent — the operator can see the valve position and the media through the body
- Inert to almost all process media; no metal in the wetted path
- PTFE spindle: no lubrication, no seizing, no contamination of the batch
- Bolts straight into the borosilicate pipeline range with the same beaded ends and backing flanges

All dimensions in mm, transcribed exactly from the catalogue page. On this table D is the included angle in degrees, not a diameter. LSPVE07 and LSPVE1 are each listed twice — the same reference and dimensions in a 90° and an 80° build — and both rows are reproduced exactly as printed. Quote the angle with the reference when ordering.
FAQ
Questions we are asked about this item.
Because the catalogue prints it twice — once at 90° and once at 80°, with identical DN, d, L and H. The reference alone does not distinguish them, so state the angle you need on the order.
No. On this table D is the included angle in degrees. The diameter columns here are DN, DN1 and d.
The same purpose as the 80° bends in the pipeline range: it puts a slight fall into a horizontal run so it drains.
