3/4" FNPT SHERWOOD 430C series stop valves rated at 6000 psi for non-corrosive gases except oxygen; 5500 psi @ 120°F. The oxygen-aluminum-silicon bronze undercoat provides exceptional long life and durability. During operation, the SHERWOOD stop valve features a forged brass body with copper alloy parts.

The 430C undercoat, c64200 aluminum-silicon bronze is not for acetylene; the 430CX undercoat, c36000 is lead-free free-machining brass acetylene handwheel spring pressure seal design is suitable for upward force. The upper stem and packing ensure a tight seal even at lower gas pressures.

The stem seal and pressure seal bonnet design guarantee a tight seal.

An O-ring seal on the upper stem prevents moisture contamination. A second seal, including a brass gasket, limits moisture intrusion. In cold (freezing) environments, SHERWOOD gate valves with PTFE seats and PTFE packing have been successfully used in SHERWOOD main shut-off valve applications for over 30 years.

The large-stem handle facilitates operation.

The Sherwood gate valve, also called a stop valve, is one of the most widely used threaded gate valves. Its popularity stems from low friction between the sealing surfaces during opening and closing, durability, small opening height, ease of manufacture, and convenient maintenance.

It is suitable for both low and medium pressures, as well as high pressures.

The closing principle of a gate valve relies on the pressure of the valve stem to tightly seal the valve disc against the valve seat, preventing media flow.

my country's valve "three-standardization" regulations once stipulated that the flow direction of gate valves should always be from top to bottom, thus requiring directional installation.

Gate valves have a longer structural length than gate valves, and also have higher fluid resistance, resulting in less reliable sealing over long-term operation. As one of the most important shut-off valves, the Sherwood gate valve plays a crucial role in the aerospace field.

As a crucial component of aerospace equipment, gate valves perform functions such as media transport, shut-off, and regulation. Their sealing performance directly impacts the safe and reliable operation of aerospace equipment.

Studying the influencing factors and laws governing the sealing characteristics of typical gate valves provide guidance for the structural design of valve sealing pairs, thereby improving valve sealing performance and reliability.

The Sherwood gate valve's working principle and characteristics: Valves play a vital role in off and throttling the media in their respective pipelines.

As an extremely important type of shut-off valve, the gate valve's sealing is achieved by applying torque to the valve stem, which in turn applies pressure to the valve disc in the cutting axial direction, ensuring a tight fit between the valve disc sealing surface and the valve.

seat sealing surface, preventing media leakage along the gaps between the sealing surfaces.

The sealing pair of the Sherwood gate valve consists of the valve disc sealing surface and the valve seat sealing surface. another commonly used shut-off valve in industrial production—the alarm valve—the gate valve is structurally simpler and easier to manufacture and maintain.

In terms of service life, the sealing surface of a gate valve is not easily worn or scratched.

During valve opening and closing, there is no relative sliding between the valve disc and the seat sealing surface, resulting in less wear and scratching of the sealing surface and thus improving the service life of the sealing pair.

The gate valve has a small valve disc stroke during full closure, and its height is relatively smaller than that of a stop valve. The disadvantages of a gate valve are that it requires a large opening and closing torque and is difficult to achieve rapid opening and closing.

Because the flow path inside the valve body is relatively tortuous, the fluid flow resistance is high, resulting in significant fluid dynamic losses in the pipeline. The American Sherwood gate valve, also known as a stop valve, is a forced-seal valve.

Therefore, when the valve is closed, pressure must be applied to the valve disc to force the sealing surface to prevent leakage.

When the medium enters the valve from below the valve disc, the resistance that the operating force needs to overcome is the frictional force of the valve stem and packing and the thrust generated by the pressure of the medium.

The force required to close the valve is greater than the force required to open it, so the valve stem diameter must be large; otherwise, the valve stem may bend. According to the connection method, there are three types: flange connection, threaded connection, and welded connection.

Since the advent of self-sealing valves, the flow direction of the medium in gate valves has changed to enter the valve cavity from above the valve disc.

In this case, under the pressure of the medium, the force required to close the valve is small, while the force required to open the valve is large, allowing for a corresponding reduction in the diameter of the valve stem.

Simultaneously, this type of valve is also more airtight under the action of the medium. my country's valve standardization regulations once stipulated that the flow direction of gate valves should always be from top to bottom.

When a gate valve is opened, the flow rate reaches its maximum when the valve disc opening height is 25% to 30% of the nominal diameter, indicating that the valve is fully open. Therefore, the fully open position of a gate valve should be determined by the valve disc stroke.

The Sherwood gate valve (stop valve, Globe Valve) uses a plug-shaped valve disc as its opening and closing element, with a flat or conical sealing surface. The valve disc moves linearly along the centerline of the valve seat.

The valve stem movement can be either a non-blocking stem or a rising and rotating stem type, which can be used to control the flow of various types of fluids, including air, water, steam, various corrosive media, mud, oil, liquid metals, and radioactive media.

Therefore, this type of shut-off valve is ideal for shut-off, regulation, and throttling.

Because of its relatively short stem opening and closing stroke, highly reliable shut-off function, and the direct proportionality between the valve seat opening and the valve disc stroke, it is well-suited for flow regulation.

SHERWOOD shut-off valves are safer – for oxygen compression, the small fluoroplastic material body of the annular seat reduces the chance of oxygen impact ignition.

The heat-absorbing metal surface encapsulation, along with the cut-off surfaces of all the seat rings acting as heat dissipation surfaces, further reduces the chance of ignition. This results in a longer lifespan and reduced risk to downstream equipment, regulatory agencies, and other auxiliary equipment.

Due to sudden increases in high-pressure gas, SHERWOOD valves quickly control flow when opening. The valve opens rapidly, and the power is directed downstream to the lower valve stem, valve body, and valve seat skirt, reducing pressure.

This function can assist equipment when high-pressure gas suddenly increases; when the valve opens to full flow, the handle is turned two full turns.
