Dikkan Bronze JIS Screwed Bonnet Gate Valves

Dikkan Bronze JIS Screwed Bonnet Gate Valves are designed for specific applications, particularly in shipbuilding where hot and cold water systems are prevalent. The valves have a pressure rating of 5K, indicating that they are designed to handle pressures up to 5 kilograms per square centimeter (kg/cm²). This specification is in accordance with the Japanese Industrial Standard (JIS). The valves come with flat-faced flanges that comply with JIS 5K standards. This indicates compatibility with the flange connection system specified by the Japanese Industrial Standard.

Key Features

Key features and benfits of Dikkan Bronze JIS Screwed Bonnet Gate Valves.
1

Key Features

The valve features an inside screwed stem. The stem is the component that connects the handwheel to the gate or disc, allowing the user to control the position of the gate.
2

Key Features

The valve has a rising stem, which means that as the valve is opened, the stem rises, providing a visual indication of the valve position. The non-rising handwheel is used to operate the valve.
3

Key Features

One of the key benefits of using bronze in valve construction is its inherent resistance to corrosion. Corrosion can be a major issue in environments where water or other corrosive substances are present, as it can lead to the degradation of metal components, compromising the functionality of the equipment over time.

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.
