CONCOA 445 Series Regulator

A marine quick-closing valve (QCV) is a crucial safety shut-off valve utilised on vessels to immediately halt the flow of flammable or hazardous fluids, such as fuel oil, diesel, or lubricating oil, during a fire or emergency situation. These valves can be operated remotely and are mandated by SOLAS (International Convention for the Safety of Life at Sea) and classification societies within machinery spaces and fuel systems.

Purpose of a Quick-Closing Valve

• To swiftly isolate fuel and oil tanks during emergencies, for instance, in the event of an engine room fire.
• To prevent fuel from exacerbating a fire.
• To safeguard personnel and diminish potential damage.
• To ensure compliance with maritime safety regulations, including those from the IMO, SOLAS, and classification societies.

We offer a wide selection of Quick Closing Valves from several leading manufacturers. For your specific requirements, please do not hesitate to contact us.

Four-Port, Chrome-Plated Brass Barstock, Rear-Entry Point-of-Use Regulator for High Purity Inert Gases

The CONCOA 307 Series regulator provides secondary pressure control for non-corrosive, liquefied, and ultra-high purity inert gases (up to grade 5.5). It is ideal for point-of-use pressure regulation in high purity gas distribution systems or for applications that can tolerate minor outlet pressure fluctuations due to diminishing supply or where inlet pressure is constant or below 500 PSIG (34 BAR). Rated to at least 3000 PSIG (210 BAR), the 307 Series rear-entry regulator is commonly used in laboratory installations and point-of-use panels.
