Gas Pressure Seal Globe Valves
Description
Technical Parameters
Introduction
In order to guarantee zero leakage even under ultra-high working pressure conditions tested to ISO 15848-1, the gas pressure seal globe valve relies heavily on its sturdy structure. This design feature ensures that the valve remains intact and securely sealed, preventing any potential gas leakage. This is especially crucial in industrial settings where the pressure can reach extreme levels. By employing a gas pressure seal, the valve is able to withstand these intense pressures, providing a reliable solution for various applications.
Features
1.Uniform structure and higher shell strength;
2.Fully guided disc is precision machined ;
3.Welded seat with stellite overlaid;
4.Low fugitive emission of stem and bonnet;
There are multiple choices available for disc types, such as conical, swivel, needle and flat. You have the option to choose the one that suits your requirements the best.
One important feature of pressure systems is the inclusion of bypass valves to prevent over pressurization and pressure locking. These valves are designed to divert excess pressure away from the main system and release it safely. In this way, they protect equipment and personnel from potentially dangerous situations. It is essential to ensure these valves are properly maintained and operational at all times to ensure their effectiveness in case of an emergency. Without proper functionality, over pressurization or pressure locking can result in serious consequences. Therefore, regular inspections and testing of these bypass valves are critical to maintaining a safe and functioning pressure system.

Body material | Stainless steel, Carbon steel, Alloy steel, and Duplex stainless steel are different types of steel used in various applications. Carbon steel is known for its high strength and durability, making it suitable for construction and manufacturing. Stainless steel is corrosion-resistant and often used in applications where hygiene and cleanliness are important, such as in the food and medical industries. Alloy steel is made by combining different elements to enhance its properties, such as strength, hardness, and resistance to wear and tear. Duplex stainless steel is a type of steel that has a mixed microstructure of ferrite and austenite, offering improved strength and corrosion resistance compared to traditional stainless steel. Each type of steel has its unique properties and applications, making them valuable materials in various industries. |
