Blast Valves<\/h2>\n

VNC-BV<\/span><\/h4>\n

VNC-BV -series Blast Dampers are designed for protection of ventilation systems against the effects of vapor and dust cloud explosions.<\/p>\n

The VNC-BV -series Blast Dampers are applied in shielding of industrial facilities, such as Oil & Gas platforms and refineries or related buildings against destructive blast forces.<\/p>\n

The VNC-BV -series offers substantially higher air flow capacity and increased level of safety, as well as flexibility in design of duct systems.<\/p>\n

Structure of the VNC-BV -series damper is corrosion free, hot dip galvanized steel or EN 1.4404 (AISI316L) in the VNC-BV-SS version.<\/p>\n

The VNC-BV -series damper has spring loaded closing blades built in a fully welded damper body to close the air passage in case of explosion or sudden increase of overpressure in the HVAC system.<\/p>\n

The threshold trigger pressure of the damper can be adjusted according customer specification.<\/p>\n

Once closed the blades will remain in closed position until they are manually reset after the incident.<\/p>\n

The VNC-BV-series dampers fulfills ATEX (Ex II 2 G D) for equipment in hazardous environment.<\/p>\n

\u2022 Fully welded damper body made of 5 mm steel<\/p>\n

\u2022 VNC-BV-blast damper is manufactured of galvanized or stainless steel, EN 1.4404 (AISI316L)<\/p>\n

\u2022 Closing blades and shafts provided with stainless steel bearings<\/p>\n

\u2022 Adjustable trigger mechanism<\/p>\n

\u2022 Fragment grill<\/p>\n

\u2022 Flow guides<\/p>\n

VNC-BV-WS<\/span><\/h4>\n

The blast valve VNC-BV-WS is for mounting on blast resistant wall surface.<\/p>\n

It is specifically designed for installation on steel walls. It can also be installed in existing buildings where casting of the valve frame in concrete is not possible.<\/p>\n

The valve is also applicable to industrial applications with risk of chemical and dust explosions.<\/p>\n

The VNC-BV-WS blast valve is available in various different sizes.<\/p>\n

Maximum height is 10 rows and width 7 columns. Contact Marine for the availability of frames with custom dimensions.<\/p>\n

The number of blocks in valve depends on the air flow requirement at desired pressure drop.<\/p>\n

When the valve dimensions do not match the opening to be covered, custom made adaptors are available.<\/p>\n

The VNC-BV-WS blast valve block comprises three spring balanced closing elements moving in a slot and closing the air passage against the valve seats in response to both positive and negative (suction) phase of the blast.<\/p>\n

The valve blocks are mounted in structual steel frames.<\/p>\n

The valve is completely corrosion resistant.<\/p>\n

The valve closing elements are made of special non-corroding aluminum alloy, all springs are made of stainless steel EN 1.4404 (AISI316L), and frame made of structural steel are hot dip galvanized.<\/p>\n

The valve blocks are mounted in structual steel frames.<\/p>\n

All the components of the valve are made of stainless steel EN 1.4404 (AISI316L).<\/p>\n

The version is especially designed for offshore and other marine applications.<\/p>\n
