Structural Characteristics
Instructions
Stem seal
Low leakage packing (API 622 certified) for a more reliable seal at stem.
Simple appearance of the butterfly plate, the intensive design of the butterfly plate parts
the thickness of the butterfly plate is greatly reduced, and the valve has a larger Cv value, which makes the flow capacity greatly improved.
Valve seat seal ring universal design
Seal ring universal design, maintenance does not need to be done, can be replaced directly on site.
Fireproof structure design
the valve seal adopts metal to metal or metal to graphite structure, and the filler adopts flexible graphite to ensure the sealing reliability of the valve in the case of fire.
Packing loading seal
the packing place adopts disc spring loading design, long-term sealing is more reliable.
Long bearing design
The self-lubricating long bearing at the valve stem can keep the valve stem coaxial, eliminate the valve switch or valve vibration load, reduce friction torque, protect the valve stem.
All-metal sealing ring
greatly extend the service life of the valve, improve the working condition, can be used in the working condition containing a small amount of solid particle medium, reduce the number of maintenance.
