PRODUCT DESCRIPTION
Tecofi PVS4241A Cast Iron Air Release Valve
PVS4241A is a Tecofi (France) single-chamber, single-function air release valve: ductile iron body, flanged, with a 1″ isolation valve, used to vent or purge air pockets collected in water pipelines. This page covers code PVS4241A only. Its sibling PVS4251A (separate page) covers DN25–DN150, PN10/16/25 flanges and stainless steel 316 bolts and nuts; the PVS4241A datasheet lists DN100 only.
Specifications
- Type: single-chamber, single-function air release valve
- Size in the datasheet: DN100
- Medium: water, waste water, compatible liquids
- Body and bonnet: ductile iron GGG50 (EN-GJS-500-7); flange: ductile iron EN1563-GJS-450
- Float (ball): ABS; seat and gaskets: EPDM; isolation valve (1″ ball valve): brass
- Nuts, washers, bolts: carbon steel
- Connection: flanged to EN 1092-2. The datasheet heading says PN10/16 while the general characteristics mention a PN25 flange

- Coating: powder epoxy RAL5015, 250 µm thick, to DIN 30677
DN100 dimensions from the datasheet (mm); the Ref. column is the order code for each size:
| DN (mm) | DN (inch) | W (mm) | H (mm) | D (mm) | K (mm) | D1 (mm) | n-d | b | f | Kg | Ref. |
|---|---|---|---|---|---|---|---|---|---|---|---|
| 100 | 4″ | 115 | 210 | 235 | 180 | 156 | 8-19 | 19 | 3 | 8.1 | PVS4241A-0100 |
| 150 | 6″ | – | – | – | – | – | – | – | – | – | PVS4241A-0150 |
Size DN150 has code PVS4241A-0150 in CAD’s catalogue, but the datasheet does not list its dimensions or weight; ask CAD before selecting it.
Difference from PVS4251A
- Size: PVS4241A shows DN100 only in the datasheet; PVS4251A covers DN25–DN150.
- Flange: PVS4241A is headed PN10/16 (DN100: K=180, 8 holes Ø19); PVS4251A is headed PN10/16/25 with PN25 for DN100–150 (DN100: K=190, 8 holes Ø23).
- Bolts, nuts and washers: carbon steel (PVS4241A) versus stainless steel 316 (PVS4251A).
- Medium: PVS4241A states water, waste water, compatible liquids; PVS4251A states water and compatible liquids.
- DN100 weight: 8.1 kg for both codes according to the datasheets.
Applications
According to the datasheet, Tecofi air release valves are used to evacuate or purge air pockets located in pipes, to improve and secure fluid circulation.
