Product Description

Breather Valve With End of Line Deflagration Flame Arrester

The Deflagration proof PRECON® Model No: 2053-CV-PVR is a precisely developed combined pressure/vacuum relief valve for high flow capacities with an inbuilt flame arrester unit. It is primarily used as a safety device for flame-transmission-proof in- and out breathing in storage tanks, storage containers and process engineering vessels. The valve offers reliable protection against excess pressure and vacuum, preventing out breathing of product vapour and inbreathing of air almost up to the set pressure and also protects against atmospheric deflagration.

The PRECON® flame arrester unit 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® 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. 

Special Features and Advantages of Breather Valve :-

Requires minimum overpressure 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.

Can be used as protective system according ATEX in areas subject to hazards.

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.

Flame Arrester Element has a low pressure drop.

Maintenance friendly design

Modular design enables individual Flame Arrester element and the valve pallet to be replaced.
