Dikkan Non Rising Stem Gate Valves

Dikkan Non-rising stem gate valves typically have a threaded stem that remains inside the valve body and rotates to lift or lower the gate. The gate itself moves up and down within the valve body to control the flow of fluid. Non-rising stem gate valves are generally easier to maintain because the stem is protected from external elements within the valve body. This design helps prevent damage to the stem, ensuring smoother and more reliable operation over time.

Dikkan Bronze Non Rising Stem Gate Valves

Bronze non-rising stem gate valves find applications in a variety of industries, including water supply systems, oil and gas, chemical processing, marine, and other industrial settings. The non-rising stem design is advantageous in installations where vertical space is limited, as the valve doesn't extend as much above the pipe. Bronze is chosen for its corrosion-resistant properties, making it suitable for applications where the valve may be exposed to corrosive substances.

Frequently Asked Questions

A gate valve is a type of valve used to control the flow of a fluid by lifting a gate out of the path of the fluid. They are often used in pipelines to control the flow of liquids like oil, gas, or water.

The main types of gate valves include solid wedge, flexible wedge, and split wedge designs. Each type is suited for different applications and fluid types.

Gate valves are best used in applications where a straight flow of fluid and minimum restriction is desired. They are ideal for on/off control rather than flow regulation.

Common materials for gate valves include bronze, iron, and stainless steel each offering different advantages in terms of strength, durability, and corrosion resistance.

Sizing a gate valve involves considering factors like the type of fluid, flow rate, pressure, and the size of the pipeline. It's crucial to consult with one of our experts or refer to manufacturer guidelines.

While possible, using gate valves for throttling is not recommended as it can cause damage to the valve and lead to increased wear.

Regular maintenance of a gate valve includes periodic inspection, cleaning, and lubrication. Replace worn parts as needed and ensure proper operation to extend its lifespan.

Signs of a failing gate valve include leaks, difficulty in operating the valve, unusual noises during operation, and a visible deterioration of valve components.

Yes, gate valves can be designed for high-pressure applications, but it's essential to select a valve that meets the specific pressure requirements of your system.

The main difference lies in their design and operation. Gate valves use a lifting mechanism to control flow, while ball valves use a rotating ball with a hole through it for flow control.

Yes, gate valves can be fitted with actuators for remote or automated control, which is especially useful in large-scale industrial applications.

Gate valves offer minimal pressure drop, tight sealing, and are suitable for high-temperature and high-pressure applications, making them a preferred choice in many industrial settings.
