Black XNBR valve seat for wafer / lug type (centerline) butterfly valve 6''-12''​


Carboxyl nitrile rubber (XNBR)

1. Basic characteristics:

1.1 Vulcanization speed is faster than nitrile rubber and easy to scorch.

1.2 Pure rubber blend shows high tensile strength.

1.3 Vulcanized rubber has good heat resistance and wear resistance. 2.1.4 Good compatibility with phenolphthalein resin.

2. Scope of application: Mainly used for hoses, seals, gaskets, oil seals, various model products and adhesives.



The butterfly valve seal is an essential component for blocking all three potential leakage paths: the sealing of pipes, flanges and operating shafts, in shut-off valves, flap valves and disk valves. In their materials and design, they must be configured optimally for the respective application.

Sealing solutions from our factory offer a precisely calibrated material quality and torque-reducing geometries. On one hand, they allow the flap to close with a low expenditure of force. On the other hand, they nonetheless feature a high pressing action for excellent sealing.

Free of both dead space and the penetration of contamination, the designs make possible hygienic applications for the food and beverage industry.

We can offer the FDA foodgrade rubber for your application.
