Model B15


Product Description

Flanged, welded or threaded EN or ASA vacuum relief valve in either spring or weight loaded available in different material options to fulfill any customer requirement available for end of line.

 

Pressure / Vacuum relief valves  model B15 are used on liquid storage tanks and other process vessels or systems to prevent structural damage due to excess internal vacuum. Storage tanks are pressurized when liquid is pumped in, compressing the existing vapor or when rising temperatures cause increased evaporation or expansion of existing vapor.Conversely, a vacuum condition may be created when pumping out or due to falling temperature. To prevent tank damage, vapor must be allowed into or out of the tank at specified vacuum condition. The volume rate of venting depends upon the tank size, volatility of the tank contents, the pumping rates and the temperature.
