working principle:

• pressure relief is performed by puncturing the seal film with a knife rest in vacuum 

• pressure relief is performed by opening the strength film in the release of pressure

technical features:

• high accuracy, working under ultra-low pressure

• bi-directional discharge design, precise laser cutting technology

• size range: 3" (80mm) to 12" (300mm)

• bursting pressure range: 1 inch water column to 150psig(10.335barg)

• standard materials can be provided, or special materials can be customized

• 3d disc label, including all parameters of the disc

• special ydcj holder

ydc series components 

 • protective ring provides protection to seal in case of positive pressure.

 • seal evenly distributes pressure in both the vacuum and positive pressure direction.•  girdle  standard material is 316ss. also, available in teflon. controls the standard min. to max. inches of water column negative(vacuum) pressure rating


 • burst indicator

 • laser cut pressure cap  provides protection to seal in case of positive pressure

 • laser cut burst cap  provides positive pressure relief at specified rating

note:this option will significantly reduce the flowing capacities in the vacuum relief basco for flow rate information.
