Specialityvalve is the largest Non-Rising Stem Gate Valve manufacturer in India. Non Rising Stem Gate Valve is a type of gate valve with a non-rising stem. A Rotating Stem Gate Valve or Blind Stem Wedge Gate Valve is another name for a Non Rising Stem Gate Valve. When the gate is opened and closed, the stem of this sort of valve does not move up and down. Because the stem is not visible, we can't tell if the gate is open or closed by looking at the valve. These valves are similar to the Rising Stem Gate Valve in that they can be used in the same applications. They take up relatively little area in the system and are suitable for both high pressure and high temperature applications. Advantages of Non-Rising stem gate valve: • Takes up less room in the system • Can withstand high temperatures and pressures • Is simple to maintain Non-Rising Stem Gate Valve is use in many industries like: • Oil and gas industry • Marine Industry • Automotive Industry • Manufacturing Industry Types of Non-Rising Stem Gate Valve: • NRS Cast Iron Gate Valve • NRS Carbon Steel Gate Valve • NRS Ductile Iron Gate Valve What makes a rising stem gate valve different from a non-rising stem gate valve? The rising stem gate valve can be identified by its look, which indicates whether the valve is closed or open. While the lead screw is visible, the non-rising stem gate valve is not. The ascension screw of a rising stem flanged gate valve is exposed from the outside, the nut clinging to the hand wheel is stationary (not rotating axial movement), and the screw and gate rotate only in a relative motion without axial displacement of the disc and stem up and down. The non-rising stem flange gate valve's lifting screw revolves rather than moving up and down.
