Sulfur-resistant manual globe valve is a kind of globe valve specially designed for sulfur-containing media environment, its structure and material selection make it can maintain good performance and sealing in sulfur-containing corrosive media. The following is a detailed introduction to sulfur-resistant manual globe valve:

Definition and working principle

Definition: Sulfur-resistant manual globe valve is a valve in which the closing member (valve flap) moves along the centerline of the valve seat, and the opening and closing of the valve is realized by rotating the handwheel or operating handle. It is suitable for different kinds of light and heavy industrial working conditions as well as construction pipelines, especially for corrosive media environment containing sulfur.

Working principle: when the handwheel rotates clockwise, the valve stem drives the valve flap to move downward, so that the valve flap and the valve seat closely fit, thus preventing the flow of media; when the handwheel rotates counterclockwise, the valve stem drives the valve flap to move upward, and a channel is formed between the valve flap and the valve seat, so that the media can flow.

Features and advantages

Sulfur resistance: sulfur manual globe valve is made of special corrosion-resistant materials, such as stainless steel (304L/R, 316L/R), etc., which can maintain good corrosion resistance and sealing in sulfur-containing media.

Good sealing: the valve has good sealing in the closed state, which can effectively prevent fluid leakage and ensure the safe and stable operation of the system.

Simple structure: composed of valve body, valve stem, valve flap and handwheel, the structure is relatively simple, easy to manufacture and maintain.

Simple operation: only need to rotate the handwheel or operating handle to realize the opening and closing of the valve, the operation is very simple.

The field of application

Sulfur-resistant manual globe valves are widely used in various environments with sulfur-containing media, such as chemical industry, liquefied petroleum gas, vehicle and ship manufacturing equipment, water, petroleum, beer, pharmaceuticals, electric power and other fields. Especially in the oil and gas mining, processing and transmission process, because the medium often contains hydrogen sulfide and other corrosive gases, so the use of anti-sulfur manual disconnecting valve is particularly important.

Selection and installation

Selection: In the selection, according to the nature of the medium (such as sulfur content, temperature, pressure, etc.), the specifications of the pipeline and the requirements of the system to determine the appropriate type and specifications of the valve.

Installation: Before installation, the model of the valve should be carefully checked to see if it is consistent with the design requirements, and installed in accordance with the direction of the valve arrow. Installation should ensure that the valve is closed, and to avoid damage to the valve in the installation process.

Maintenance and repair

Regularly check the sealing and operating flexibility of the valve, abnormalities should be dealt with in a timely manner.

When stored for a long time, it should be placed in a ventilated and dry place and inspected and maintained regularly.

For wearing parts (such as seals, etc.), should be regularly replaced to ensure the normal operation of the valve.

In summary, sulfur manual globe valve is a valve with excellent sulfur resistance and sealing performance, in the sulfur-containing media environment has a wide range of application prospects. In the selection, installation, use and maintenance process, it should be operated in strict accordance with relevant regulations and requirements to ensure the safe, reliable and stable operation of the valve.
