Arvind Pipes is one of the largest gate valve manufacturers in India. Gate valves are linear motion valves primarily used to start or stop the flow of fluid in a pipeline. They operate by lifting a solid gate or wedge out of the fluid’s path. When fully open, gate valves offer minimal resistance to flow, making them ideal for applications that require full, unobstructed flow. These valves are not designed for throttling, as partially open gates can cause vibration, erosion, or damage to the valve.
As a trusted gate valve supplier in India, we provide gate valves that are widely used in water supply systems, oil and gas pipelines, chemical plants, and power stations. These valves are available in a variety of materials, such as cast iron, stainless steel, brass, and bronze, to suit different environments and media. Due to their ability to withstand high-pressure and high-temperature conditions, gate valves are a popular choice for isolation in both above-ground and underground installations.
Type of Sub-products
Solid Wedge Gate Valve
Solid wedge gate valves are the most commonly used type, featuring a single-piece solid disc. They are known for their strength and durability, making them ideal for high-pressure and high-temperature environments. However, they may not perform optimally in systems with frequent temperature fluctuations due to potential binding.
Flexible Wedge Gate Valve
Flexible wedge gate valves have a single-piece disc with a slight cut or groove to allow flexibility. This design helps accommodate thermal expansion and contraction, making them suitable for applications with temperature variations. They are commonly used in steam systems and thermal cycling processes.
Frequently Asked Questions
What are gate valves used for?
Gate valves are commonly used in water supply systems, oil and gas pipelines, power plants, and other industrial applications where on/off control is required and frequent operation is not needed.
How do I know if a gate valve is open or closed?
Typically, when the valve stem is visible (rising stem design), the valve is open. When it’s fully retracted, the valve is closed. Non rising stem designs may require position indicators.
What is the difference between a rising stem and a non rising stem gate valve?
In rising stem valves, the stem moves up when the valve opens, making it easy to see the valve position. In non rising stem valves, the stem stays in place, and the gate moves inside.
