Pressure and vacuum relief breather valve is designed to protect low pressure storage tanks from excessive Pressure (or vacuum) created by thermal expansion (and contraction) and product movement into(out of) the tank and at the same time minizing costly product evaporation/loss.
Excesses in pressure or vacuum may also cause permanent deformation to the tank or unbalance a vapor recovery system.
The pressure and vacuum relief breather valve is installed on the storage tank roof. The valve may be mounted in onjunction with a KSFH or KSFI flame arrester to provide maximum protection against excessive pressure and vacuum while minizing accidental ignition of flammable product vapor from external sources.

• Available vertical & horizontal installation
• High quality corrosion & chemical resistance
The model KSFI inline flame arrester is designed, manufactured and tested according to EN ISO 16852.
The unit are passive devices with no moving parts.
They prevent the propagation of flame from the exposed side of the unit to the protected side by the use of a 316L stainless steel crimped metal ribbon type flame cell element.
This construction produces a matrix of uniform opening that are carefully constructed to quench the flame by absorbing the heat.
This provides an extinguishing barrier to the ignited vapor mixture.
The KSFI flame arrestors have specifically designed heat transfer characteristics for slow moving flames and low medium pressure fronts (low to medium deflagration).
Inline flame arresters can be installed either vertically or horizontally within a designated distance from the potential ignition extras.
The standard flame cell is suitable for NEC group D or IEA IIA gases. Cells for other gas groups are avbailable as additional extras.
The flame arresters are available with either aluminum, nodular iron, cast steel, 304SSss, 316SS and 316LSS housings, Iron and steel housings are supplied epoxy coated.
Sizes range from 15mm to 600mm and available upon request.
Standard flanges are ANSI 150lb and other connections are available upon request.
The flame arresters have additional Atex cert.(2"~12")
