GTL-Z45X Resilient Seated Gate Valve has the characteristics of sensitivity, reliability and easy installation. Can be widely used in tap water, hot water, sewage, construction, petroleum, chemical, food, medicine, textile, electric power, ships, gold, energy systems and other fluid pipeline as a regulator and closure device. Elastic seat seal gate valve is also called lifting rod gate valve. Usually trapezoidal threads on the lifting rod convert the rotary motion into linear motion, that is, the operating torque into operating thrust, by means of the nut at the top of the valve and the guide slot in the valve body. When the valve is opened, the flow path is clear when the gate lift height is equal to 1:1 valve size, but this position cannot be monitored during operation. In actual use, the vertex of the stem as a mark, that is, the position of not moving, as its full open position. In order to consider the temperature changes occur locking phenomenon, usually open to the top position, and then rewind 1/2-1 turn, as the position of the fully open valve. Therefore, the full open position of the valve is determined by the position of the gate (i.e. stroke).
