Ggg40 Pn10 Ductile Iron Non Rising Stem Gate Valve For Potable Water Supply

Ggg40 Pn10 Ductile Iron No Rising Stem Resilient Seat Gate Valve For Potable Water Suppl Gate Valve Flange Typey

product description:

The gate valve of the gate valve moves in a straight line with the valve stem, which is also called a rising stem gate valve. Usually there is a trapezoidal thread on the lifter, and through the nut at the top of the valve and the guide groove on the valve body, the rotating motion is changed into a straight line motion, that is to say, the operating torque is changed into the operation thrust. When the valve is opened, when the lift height of the gate plate is equal to 1:1 times the diameter of the valve, the passage of the fluid is completely unblocked, but this position cannot be monitored during operation. In actual use, the apex of the valve stem is used as a sign, that is, the position where the valve stem does not move is taken as its fully open position. In order to consider the locking phenomenon of temperature changes, it is usually opened to the top position, and then reversed 1/2-1 turn, as the fully open valve position. Therefore, the fully open position of the valve is determined by the position of the gate (that is, the stroke). Some gate valve stem nuts are set on the gate plate, and the rotation of the hand wheel drives the valve stem to rotate, thereby lifting the gate. This kind of valve is called Rotary stem gate valve or dark stem gate valve.

The main advantages of gate valve include:

Advantages of gate valves

a. Fluid resistance is small. Because the medium channel inside the gate valve body is straight through, the medium does not change its flow direction when it flows through the gate valve, so the fluid resistance is small.

b. The opening and closing resistance is small. Because the direction of movement of the gate is perpendicular to the flow direction when the gate valve is opened and closed, compared with the globe valve, the opening and closing of the gate valve is less labor-saving.

c. The flow direction of the medium is not restricted. The medium can flow in any direction from both sides of the gate valve, which can achieve the purpose of use, and is more suitable for pipelines where the flow direction of the medium may change

d. The structure length is shorter. Because the gate valve of the gate valve is placed vertically in the valve body, while the disc of the globe valve is placed horizontally in the valve body, so the structural length is shorter than that of the globe valve.

e. Good sealing performance. When fully open, the sealing surface is less eroded.
