How is pressure rating influence the gate valve?

The pressure rating significantly influences the performance and suitability of a gate valve. Let’s delve into how it impacts this type of valve:

Maximum Operating Pressure

The pressure rating determines the maximum pressure that the gate valve can safely handle. It is usually measured in pounds per square inch (psi) or megaPascals (mPa) in Europe 1. When selecting a gate valve, understanding the maximum operating pressure of your system is crucial. Opt for a valve with a pressure rating higher than your system’s requirements to provide an added safety margin.

Gate Valve Behavior

Gate valves are designed to open fully and leave the flow bore virtually free of encumbrances or friction. When the gate valve is fully open, it offers minimal resistance to flow, similar to a section of pipe of the same port size. However, gate valves are generally not suitable for regulating flow or operating in partially open positions. Using them for throttling can lead to damage due to the seating surfaces banging against each other in turbulent flow conditions.

Influence on Operation

As the pressure of the medium pushes the gate against its guiding rail, operating the valve becomes more challenging. Influences on big size gate valves and underground gate valves:

Gate Valve: A Fundamental Component for Efficient Flow Control

Gate Valve: A Fundamental Component for Efficient Flow Control

Gate valves play a vital role in efficient flow control systems across various industries. With their robust construction, reliable sealing capabilities, and ability to handle diverse fluids, gate valves provide an essential component for on/off service and straight-line flow control. From oil and gas to water treatment, power generation to chemical processing, gate valves find extensive usage in critical applications.

Understanding Gate Valves

Gate valves are linear motion valves that are primarily designed for on/off service in systems that require a straight-line flow of fluid. The key element in a gate valve is a sliding gate or wedge, which is positioned perpendicular to the flow direction within the valve body. When the gate is raised, it allows fluid to pass through the valve, and when it is lowered, it blocks the flow, providing a tight shut-off.
The construction of a gate valve typically consists of a valve body, a gate, a stem, and a bonnet. The valve body is usually made of materials such as cast iron, ductile iron, carbon steel, or stainless steel, depending on the application and the fluid being controlled. The gate, which can be either solid or flexible, moves up and down within the valve body to regulate the flow. The stem is connected to the gate and provides the linear motion required to open or close the valve. The bonnet houses the stem and provides a seal to prevent leakage.

Functionality and Benefits

Gate valves offer several advantages due to their unique design and functionality. One of their key benefits is their ability to provide a full flow area, resulting in minimal pressure drop when the valve is fully open. This characteristic makes gate valves suitable for applications where a low pressure drop is desired, such as in large pipelines or high-pressure systems.

Gate valves also offer excellent sealing properties. When fully closed, the gate comes into contact with the seat, creating a tight seal that prevents leakage. This feature makes gate valves ideal for applications that require a reliable shut-off, such as in the oil and gas industry, water treatment plants, and chemical processing facilities.

Another advantage of gate valves is their ability to handle a wide range of fluids, including liquids, gases, and slurries. Their versatile design allows for effective control over different types of media, making them suitable for various industries and applications.

Types of Gate Valves

Gate valves can be categorized into different types based on their design and operation. Some common types include:

Rising Stem Gate Valve: In this design, the stem moves in an upward direction as the valve is opened, providing a visual indication of the valve position.

Non-Rising Stem Gate Valve: In this design, the stem does not rise as the valve is opened or closed. This type of valve is often used in applications with limited vertical space. Certainly, meanwhile, TWT also provides China non-rising stem gate valve to customes.

Wedge Gate Valve: The gate in this design is shaped like a wedge, offering a tight and reliable seal. Wedge gate valves are commonly employed in high-pressure applications.

Parallel Slide Gate Valve: In this design, the gate moves in a parallel motion rather than perpendicular to the flow direction. This type of gate valve provides enhanced sealing capabilities and is suitable for high-temperature applications.

Applications and Industry Usage

Gate valves find widespread applications in numerous industries, including oil and gas, water and wastewater treatment, power generation, chemical processing, and many more. Their versatility and ability to handle a wide range of fluids make them indispensable in various systems.

In the oil and gas industry, gate valves are commonly used for isolation and control in pipelines, refineries, and offshore platforms. Water treatment plants rely on gate valves for regulating water flow, controlling pumping systems, and managing the distribution of water. Power generation facilities utilize gate valves for controlling steam, cooling water, and other process fluids.

Gate valves are also employed in the chemical processing industry, where they are used to control the flow of corrosive or hazardous fluids. Additionally, gate valves find applications in fire protection systems, HVAC systems, and irrigation systems, among others.

In this article, we will take a closer look at underground gate valve design with a focus on manual operation models. Understanding the engineering considerations that go into manual underground gate valves can provide valuable insights for specifying, installing and servicing these critical underground infrastructure components.

Compliance with Industry Standards

non rising stem resilient seated gate valve manufacturer

All underground bs5163 gate valve pn16 must be engineered and manufactured according to relevant industry standards to ensure safety, quality and interchangeability. In the UK, underground gate valves designed for potable water distribution networks up to PN16 pressure rating comply with BS5163:1992. This British Standard specifies technical requirements for the construction, testing and performance of buried sluice valves up to 1200mm in nominal diameter.

Key aspects covered in BS5163 include body and bonnet materials, joint types, operating mechanisms, pressure rating, flow direction indicators and extension stems for underground access. Manufacturers of BS5163 compliant underground gate valves use high strength ductile iron or fabricated steel to construct robust bodies capable of withstanding underground installation and the working pressures of water distribution systems.

Manual Operation Design

When it comes to manual underground gate valves, the operating mechanism is a critical design element that needs to provide reliable actuation from above ground level. Most modern manual underground gate valves utilize a buried valve bonnet with an adjustable valve box and operating stem arrangement.

The valve bonnet houses the gate, seat rings and stem connections below ground. It features a stem guide bushing and rising stem that translates the open/close movement directly from the gate. Extending up from the valve bonnet is the operating stem – a threaded shaft often constructed from bronze, stainless steel or galvanized steel materials.

The operating stem passes up through the center of a concentric valve box installed flush with the final grade. This precast concrete or polymer concrete valve box protects the operating components while providing accessible access. A adjustable extension stem sits atop the valve box and connects to the buried stem with a junction box. T-handled, lever, or nut operated extensions allow manual operation from grade level.

Sealing Design

Reliable sealing is crucial to prevent leakage which could lead to contamination or erosion issues over the lifetime of an underground valve. BS5163 gate valves pn16 utilize resilient wedge sealing which provides drip-tight shutoff with minimal operating torque.

In resilient wedge sealed gate valves, an elastomer wedge mounted on the gate compresses against a dual segmented seat in the valve body. This forms a flexible seal as opposed to metal-to-metal sealing. The resilient wedge maintains sealing integrity in either flow direction and allows for easy replaceability if needed. O-ring stem seals within the valve bonnet further contain pressures and prevent underground contaminants from entering the operating mechanism.

Maintenance Considerations

With underground installation, maintenance access is an important design factor for gate valves. The manual operation arrangement enables valves to be cycled annually and lubricated as needed through the top opening of the adjustable valve box. Valve boxes should be level with final grade and not subject to heavy traffic loads to avoid damage.

Additionally, an air release/vacuum breaker attachment may be included on underground gate valves to release built-up pressure when isolating a section of water main during maintenance activities. This reduces mechanical stresses on the valve and piping system. Gate valves also require occasional external coating touch-ups to protect against corrosion if the factory applied coating becomes damaged over time.
