Design options of Shutoff Valve PN 10, 16, 40
Main design features and advantages
- Body and flanges are die-forged to ensure their structural strength, and durability..
- The areas of valve body and stem that provide shutting off are hardfaced with corrosion resistant and high strength alloys and then ground in to contribute to more pressure integrity and tightness and longer lifetime.
- Packing stem set consists of self-sealing fluoroplastic packing rings that offer perfect tightness and low friction coefficient.
