summary

Stem seal:

Three independent sealing rings are used to ensure the permanent sealing of the upper seal. If the wear of the sealing ring is prolonged after long-term use, the sealing can be restored by tightening the upper gland bolt.

Stem design:

The valve has small pressure, small friction and self-control.

Main seal ring:

Replacement of sealing ring under pressure on line can prevent leakage.

Disc:

Ductile iron material, seal ring for copper alloy, surface through precision processing, can be well integrated with the valve body seal ring. The sealing ring is accurately machined and stably pressed in the dovetail groove on the valve disc. The internal and external surface of the product is coated with epoxy resin to ensure long-term use without corrosion.
