AS-Schneiderin valmistama laadukas neulaventtiili vaativaan käyttöön eri teollisuuden tarpeisiin.
Neulaventtiilit
- Packing: PTFE and Graphite Packings are available for all valve types except the N334 Needle Valve which has an O-Ring stem seal.
- Surface Treatment: Carbon Steel Valves are phosphatized by default.
- Pressure Test: A shell test and a seat test are performed at 1.5 times the max. allowable (working) pressure acc. to EN 12266-1 – P10, P11 and P12 respectively MSS-SP61 at every standard AS-Schneider Needle Type Globe Valve.
- Certification: Inspection certificate 3.1 acc. to EN 10 204 for valve body material and pressure test available on request. The heat resisting materials are available by default with inspection certificate 3.2!
