Product Description

Breather Valve With End of Line Deflagration Flame Arrester

The Deflagration proof PRE’CON® 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 PRE’CON® flame arrester unit is designed to achieve minimum pressure drop with maximum safety. The deflagration-proof PRE’CON Model No: 2053-CV-PVR is available for groups IIA to IIB3. The tank pressure is maintained up to the set pressure with a tightness that is far superior to the conventional standard due to our state of the art manufacturing technology. This feature is ensured by the individually lapped valve seats made of high quality stainless steel and with an air cushion seal in conjunction with high quality FEP/PTFE diaphragm. The valve pallets are available with a PTFE seal to prevent the valve pallets from sticking when sticky products are used and to enable the use of corrosive fluids.

After the in- and out breathing is completed the valve re-seats and provides a tight seal. If the set pressure is exceeded, gas/product-vapour air mixtures are released to the atmosphere. If this mixture ignites, the integrated PRE’CON® 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. Standard material of construction for body is Cast Aluminium, Cast Steel, Stainless steel 304/316. Seats & Pallets are made of Aluminium, Stainless Steel 304/316. The seats are easily replaceable.

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.
