Description:
AZ Series Resilient seated NRS gate valve is a wedge gate valve and Rising stem (Outside Screw and Yoke)type, and suitable for use with water and neutral liquids (sewage) . The OS&Y (Outside Screw and Yoke) gate valve is mainly used in fire protection sprinkler systems. The main difference from a standard NRS (Non Rising Stem) gate valve is that the stem and stem nut are placed outside the valve body. This makes it easy to see if the valve is open or closed, as almost the entire length of the stem is visible when the valve is open, while the stem is no longer visible when the valve is closed. In general this is a requirement in these kinds of systems to ensure a fast visual control of the system status..
Features:
Body:No groove design,prevent from impurities,ensure effective sealing.With epoxy coating inside,conform to potable water requirement.
Disc:Metal frame with rubber lined,ensure valve sealing and conform to potable water requirement.
Stem:Made of high strength materials,ensure gate valve easily controlled.
Stem nut:The conection piece of stem and disc,ensure disc easy operating.
