Flame Arresters

PRECON Breather Valve with Flame Arrester is designed to achieve minimum pressure drop with maximum safety. The deflagration-proof PRECON Model No: 2053-CV-PVR is available for groups IIA to IIB3. If the set pressure is exceeded, gas/product-vapour air mixtures are released to the atmosphere. If this mixture ignites, the integrated PRECON Breather Valve with Flame Arrester prevents flame transmission resulting from atmospheric deflagration into the tank. The vacuum side is also protected against atmospheric deflagration. The valve can be used up to an operating temperature of +60°C and meets the requirements of European tank design standard EN 14015 Appendix L and ISO 28300 (API 2000). Type-approved in accordance with the current ATEX Directive and EN ISO 16852.

Features:

• Requires minimum over pressure to full lift. More design flexibility through higher reseating pressures; vents reseat when conventional vent is still discharging costly product or nitrogen
• High performance seal reducing product loss.
• The Breather Valve pallet is guided within the housing to protect against harsh weather conditions.
• Flame Arrester Element provides protection against atmospheric deflagration.
• Flame Arrester Element integrated into the valve saves space, weight and reduces cost.
• Flame Arrester Element protected from clogging through product vapour.
