Product Features:
▪Double Sealed
During the whole service life, the valve can keep both-way close and 200% no leakage every time.
▪Non-friction Upper Seal
When the valve is fully open, change the upper seal under pressure, no need to cut the operation.
▪Low Close Torque
The wedge can go down while sealing, the final close torque is extremely low than the traditional design. Low close torque only need the small valve actuator, reduce the installation cost.
▪Excellent Close Performance
The wedge compresses only at final 20% location of the closing route, one step, no need to retighten, the wedge cannot rebound.
▪Wedge with Whole Guide Rail
The edge of wedge integrates low friction guide rail, the rail will not produce brake resistance during the installation at the horizontal and vertical directions.
▪Unfading Product Label with Barcode
Be easy to trace the products and manage the inventory
▪Double Thread Stem
Reduce the time and turns of closing and opening, lower the labor cost.
▪Full Aperture
The smooth channel of full aperture cannot hide the junk in the pipe, is good for drilling under pressure and cleaning operation.
▪Extension Bar
The bonnet of A type product accords with the need of GW336, allows to use convenient operating extension bar. We also offer the extension bar equipment of B type product.
▪Plastic Protection Suite
Offer better protection for the products during the storage, transportation and installation.
