Product Description

American Standard Stainless Steel Flange Gate Valve

Stainless steel American standard Gate Valve structure features

1. Features of stainless steel American standard gate valve:

●The valve bearing parts are cast by precision casting process, the surface quality hand wheel is casted by malleable cast iron, the shape is matched with the handle, and the friction is appropriately increased.

●The stem nut is made of high-nickel ductile iron. The [T"-shaped thread cooperates with the valve stem to transmit torque.bellows valve, Safety Valve, gate valve, Check Valve, Ball Valve,

● There is an oil cup on the bonnet, which can be replenished with solid lubricant regularly to keep it easy to open and close.

●The packing gland and the pressure sleeve are designed separately to ensure the concentricity of the valve stem. Reasonable stuffing box design to ensure that the valve has no external leakage.

2, stainless steel American standard gate valve meets environmental protection requirements.

● The bonnet is equipped with an upper seal that meets the American Petroleum Institute API standards.

●The middle flange connection bolt of the valve adopts stud bolt for easy maintenance and disassembly.

●The stem of the valve stem is forged as a whole and connected to the valve disc through a "T" groove to ensure strength.

●The castings below DN250 are precision casting. Each batch of castings has a furnace number for easy tracking.

3, stainless steel American standard gate valve easy torque transmission structure:

The hand wheel transmits torque to the valve stem through the stem nut. The valve stem is forged and tempered by A182F6 (1Cr13), and the hardness is HB220-250. In order to reduce the loss of force during the transmission process, the stem nut is made of high-nickel ductile iron A439GR.D2 or copper alloy (high-nickel ductile iron has a certain self-lubricating property), and the hardness is about HB50 smaller than the valve stem.
The large-diameter, high-pressure valve can be equipped with a thrust bearing on the top and bottom of the stem nut. At the same time, it has an oil cup structure, which can be regularly added with solid grease to keep the lubrication, so that the valve has a lighter torque.

4, stainless steel American standard gate valve design reasonable anti-leakage stuffing letter:

The valve packing is a combination of flexible graphite and braided graphite, which has good sealing performance and certain strength. The packing gland and the packing gland are split design, the spherical surface is combined, and the concentricity can be automatically maintained, so that the valve stem is not scratched when moving up and down. The packing gland is provided with a step to prevent it from falling into the stuffing box. The threaded tail of the stem is always above the packing to prevent the packing from coming out during movement. This stuffing box ensures that the valve has no external leakage and meets environmental requirements.

5, stainless steel American standard valve stem head and the brake plate reliable connection:

The gate valve stem is integrally forged with A182F6 (1Cr13) and has strong tensile strength, ensuring that the stem of the valve stem will not be trapped in the valve body due to fault breakage.
The stem head is provided with an upper sealing surface sealed with the bonnet sealing pair. When the medium is used, the valve is required to have no external leakage when fully opened.
The connection between the stem of the valve stem and the gate adopts a "T"-shaped groove structure, and the two have a certain degree of freedom, so that the gate slides smoothly into the valve seat along the guide body of the valve body.

6, stainless steel American standard gate valve can replace the valve seat with a certain amount of wear:

The valve seat of the gate valve is connected with the valve body by a threaded connection, which is convenient for maintenance and replacement. The static sealing surface of the seat is precision ground and screwed into the valve body with a special tool for a reliable seal.
The sealing surface of the gate is wider than the sealing surface of the valve seat, and the bottom line of the sealing surface of the valve is not at the same height as the bottom line of the sealing surface of the valve seat, so that the valve will not wear even after being used for a certain period of time. Reduce the width of the sealing surface that must be guaranteed.
