Static Flame Arresters

Our Static Flame Arresters series are made with the strictest IMO standards in mind, offering the highest possible safety standards and unsurpassed operational performance. These flame arresters provide protection against the passage of flames should a fire occur on board, while securing that gas emissions are kept at a minimum.

Available in three versions

EFA-E Type Valve

The EFA-E end-of-line endurance burn proof flame arrester is developed for seagoing and inland tanker vessels.

EPV Type Valve

The EPV vertical, end-of-line flame arrester is ideal for small and medium capacities.

VFA Type Valve

The VFA flame arrester is ideal for versatile cargoes and small to medium capacity applications. Applicable for oil tankers and old-fashioned common venting systems

Safety and Compliance

The marine sector is restricted by several rules and regulations stipulated by leading classification societies. The EPV valve has been subjected to severe tests in order to meet these market demands for high quality and safety.

All of our valves have completed vigorous testing to ensure the safest voyages for crew and cargo.

The EPV Valve is approved in accordance with IMO/Circ. 677 and EU-MED. The type is also approved by major classification societies.

VFA – Vertical Efflux Flame Screen

Type VFA features extreme low pressure drop and is designed for high capacity applications such as oil tankers with old-fashioned common venting systems. For applications with highly volatile crude – typically shuttle tankers where pressure control valve type N is used – type VFA features adequate drainage ports that are connectable to collection facilities.

The typical installation where a high capacity flame screen is used will feature either small breather valves (type FLS) on each tank (common venting) or full sized high velocity vents (type HSIMO2) on each tank for full safety independent on crew routines (individual venting).

Consequently, the flame screen is not the source of relief for thermal variation or sloshing. When selecting the right size of flame screen, the most important aspect is a careful pressure drop calculation according to IMO MSC/Circ.731 to ensure that the p/v valves do not operate prematurely or cause excessive leakage.

VFA Features

  • IMO approved as explosion safe
  • Compact size compared to capacity
  • Efficient drainage for high vapor pressure crude
  • Easy maintenance
  • Simple and rigid design
  • Adjustable net clearance to reduce oil mist formation
