Description
Features of Resilient Seated Gate Valve
- Full diameter flat – bottom runner, no debris pooling;
- Fully covered EPDM disc, no corrosion;
- Movable disc’s nut, adaptive offset;
- The variable pressure change O-Ring.
Resilient Seated Gate Valve Working Principle
The main seal is entirely rubber covered gate, under the action of operating force and hydraulic pressure produced a small amount of adaptive elastic deformation, and precision casting of the seating stroke excellent sealing effect.
Resilient Seated Gate Valve Installation and Commissioning
If maintenance is required, the o-ring can be replaced online directly on the pipe. When installed, pay attention to the use of temperature and corrosivity, can be used to replace rubber parts suitable for the use of temperature. For specific use, please consult ZECO Valve Group.
