Bellows Type Safety Valve Descriptions

Bellows type safety valve is the ideal over pressure protection device for pressure equipment, pressure vessel and pipeline with steam or other dangerous mediums. When the medium pressure increases and exceeds the allowed pressure, the bellows safety valve will open automatically to discharge fully, protecting the medium pressure from being increased continually. When the medium pressure reduces to the set up pressure, the relief valve will close timely, making sure the equipment or the pipeline work safely.
The bonnet of full sealed safety valve is sealed, preventing the dust or foreign matters from invading into the bonnet and preventing the toxic or inflammable mediums overflow from the bonnet. Open type safety valve is good for reducing the temperature in the bonnet for its bonnet is open, which is mainly applicable to steam pipeline and vessel. The bellows safety valve with radiator is mainly applicable to the conditions of mediums with temperature 300℃ – 570℃.
The spring loaded safety valve with lever can be open with lever when the medium pressure reaches more than 75% of discharge pressure. Flowspec Luokai can produce the bellows type safety valve according to ISO4126, API RP520, JIS8210 and DIN3320.
