Product characteristics

1. Low leakage fireproof packing to prevent valve stem leakage and achieve fireproof function

2.Overall forged lengthened bonnet, structured without weld joint

3.Fully machined bonnet bore, small clearance between the bonnet bore and the valve stem, good cooling effect.

4.The upper seal is located under the stuffing box to prevent abnormal pressure rise in the inner cavity of the bonnet when it is fully opened.

5.Overlaid cobalt-based alloy on the seal surface to ensure the service life.

6.The relief hole of the gate plate is opened to prevent abnormal pressure rise in the valve cavity.
