1. Wear resistance: because the vальве core of hard seal bвсеvальве is spray welded with alloy steel and the sealing ring is overlaid with alloy steel, the hard seal bвсеvальве will not have too much wear when opening and closing.
2. Good sealing performance; as the hard sealing bвсеvальве is sealed by mгодовойgrinding, it can not be used until the vальве core and sealing ring are completely consistent. So his sealing performance is reliable.
3. Light switch: since the bottom of the seal ring of the hard seal bвсеvальве is tightly held together with the vальве core by the spring, the switch is very light when the external force exceeds the preload of the spring.
4. Длительный срок службы.
