Angle Valve for Shutoff and Control PN 20; 40
Features and advantages
- The areas of the 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.
- Body and flanges are die-forged to ensure their structural strength and durability..
- Packing stem set consists of self-sealing Teflon packing rings that offer perfect tightness and low friction coefficient.
- Valves with sizes 65, 80 and 125 mm involve a load relief device that offers reducing stem forque.
- Coupling and overall dimensions, and weight of the valves with PN 200 bar are specified in Table 2, that of the valves with PN 400 - in Table 3.
