detailed

The cast steel pressure safety valve is an automatic pressure release device activated by static pressure upstream of the valve. Notable for its rapid full opening or explosive action, it is typically employed in gas or steam services.

Safety Valve/pressure safety valve, angle type
Full Lift Safety Valve: Capable of achieving maximum lift during operation, allowing for efficient pressure relief.
Conventional type, Standard safety valve for fluids and gas
Metal-to-Metal Seated: Ensures a tight seal and durability, even under high-pressure conditions.

Equipped with flanged connections compliant with ANSI B16.5 standards

Standards Compliance

 

Design and Manufacture: API RP 520
Face to Face(end to end): API 526
Test and Inspection: API 527

Approved for gases, vapours and fluids
Working temperatures: Lower than 300°C

 

Advantage

 

1.Simple shape, short structural length, good manufacturing process, its versatility allows for wide application across various industries.
2.With minimal flow resistance, the valve enables smooth fluid or gas flow.
3.nstallation is straightforward, thanks to its user-friendly design and compatibility with standard installation procedures.
4.Less effort when opening and closing, reducing strain on the operator, thereby enhancing ease of use and maintenance.

 

Features

 

1.The solid nozzle screws into the body. its maintenance is easy
2.The shape of the valve disc holder is specially designed to enhance the effect of fluid thrust, thereby achieving instantaneous lifting of the valve disc

3.The choice of material is careful. The manufacture of the spring and the bellows has strict technological process. Each of them is tesed and checked strictly
