Syveco offers five different models of resilient seated gate valves. All of them are made in GGG50 cast iron, this material being stronger than grey cast iron, and coated with epoxy paint inside and outside, in order to prevent any risk of corrosion.
You will get efficient and thoughtful service from Yaxing Valve.
Two main elements guarantee the tightness of our resilient seated gate valves:
- Rubber-coated gate, ensuring full tightness;
- Tightness at shaft is reinforced by a triple NBR O-ring.
There are a number of options available as regards the actuators: handwheel with non-rising stem, handwheel gearbox, square drive nut, stem extension (optional). These actuators are operated with a clockwise to close (CTC) or a clockwise to open (CTO) movement.
There is a difference between short face-to-face valves (DIN F4 or EN 558 series 14) and long face-to-face valves (DIN F5 or EN 558 series 15).
These valves are full bore valves, which means there is no head loss when the fluid runs through the valve. Resilient seated gate valves are also versatile valves, as it is possible to use them in above-ground installations as well as in underground systems.
Plus: online maintenance is available.
