Features

• Self-rotating, self-grinding sealing surface, sharp valve disc cleans the sealing surface, forming an extremely long service life.

• The sealing surface is sprayed with cemented carbide, or the whole sintered cemented carbide, which effectively improves the compactness, adhesion and hardness of the coating and prolongs the service life.

• Rotating valve stem no up and down lifting movement, spring loaded packing design, no need to change frequently to avoid leakage.

• Effectively solve the problem of hard particle cutting, stable performance, long-term operation, and replace imported products of the same working condition.
