Cast Steel Gate valves Glofa Supplied can be fully opened and fully closed to be used for cutting in the pipeline.The entire flow channel is a straight-through passage when the valve is fully-open, and the pressure loss is minimum.Gate valve is usually for working condition in which the valve is not opened or closed frequently, Itâ??s not suitable for adjustment or throttling. The most important feature of the cast steel gate valve of Glofa produced is that they can be ensured that the permissible leakage rate can be lower than that specified in API 6D and API 600, and the middle shaft sealing can pass the USA VOC leakage test. The wedged gate of the Glofaâ??s gate valve provides tight sealing even at low differential pressure. Grooved wedge guided and fitted by body, assures proper and consistent seal regardless of valve position, and also minimizes seat wear and damage, since seating surfaces of the wedge and seat are in contact during less than 5% of the total wedge travel.

Galvanized bolts are bolts that have undergone a galvanization process, which involves coating the bolts with a layer of zinc to provide protection against corrosion. The galvanization process creates a protective barrier that helps prevent the bolt from rusting when exposed to moisture and other corrosive elements.
