Fluidyne Instruments Private Limited

FLUIDYNE API 2000 Code EMERGENCY VENTS Model EVV-110 are for storage tanks when exposed to overpressures that are not handled by standard tank vents. These vents provide the capacity to meet API standard 2000 for emergency venting due to fire exposure when properly sized. These covers also provide quick easy access for tank inspection and maintenance and provide pressure relief. When excessive pressure builds within the storage tank the FLUIDYNE series Emergency Pressure Relief Vent begin to open at a predetermined set pressure relieving excessive pressure. When the overpressure has dissipated the cover reseat onto the base. FLUIDYNE emergency vents are available in several materials that are corrosion resistant to most petroleum product applications. The setting range is from a minimum of 25mm W.C to a maximum of 200mm W.C. for direct-weight loaded and 2000mm WC for deadweight-lever type. This model is available with Weight Loaded Lever type for adjustable settings and higher pressure settings.

FLUIDYNE API 2000 Code EMERGENCY VENTS are designed to provide emergency pressure relief for storage tanks when exposed to overpressures that are not handled by standard tank vents. These vents provide the capacity to meet API standard 2000 for emergency venting due to fire exposure when properly sized. These covers also provide quick easy access for tank inspection and maintenance and provide pressure and vacuum relief. Vacuum relief must be achieved by special spring loaded venting devices attachment in such emergency pressure and vacuum relief vent covers. When excessive pressure builds within the storage tank the FLUIDYNE series Emergency Pressure Relief Vent begin to open at a predetermined set pressure relieving excessive pressure. When the overpressure has dissipated the cover reseat onto the base. FLUIDYNE emergency vents are available in several materials that are corrosion resistant to most petroleum product applications.

Fluidyne make Vacuum Relief Breather valves or Vacuum Breakers are manufactured in various models and combinations depending on the application. Fluidyne make Vacuum Relief Breather valves or Vacuum Breakers are available in dead weight and spring loaded types and lever operated dead weight type for variable vacuum setting. Fluidyne make Vacuum Relief Breather valves or Vacuum Breakers are available for every industrial application from materials like Cast Iron, Cast Steel, Stainless Steel, Aluminium, etc.

Fluidyne have designed level gauges, indicators and valves with utmost care for getting the maximum economy accuracy and durability. Your level indicators and level gauge should have the same strength as your vessel to withstand the high pressures to which it is subjected and the corrosive characteristics of the fluid. Also, your valuable process fluid should never leak out through the glass fitting. In industries, you may have to measure the levels of colorless liquids, interface of immiscible fluids, liquids with sub-zero temperatures and liquids with too much foaming. All these requirements can be met with by our latest types of tubular level gauges, flat glass level gauges and magnetic non-contact type level indicators. Fluidyne manufactures following type of Level instruments

FLUIDYNE Pilot Operated Breather Valves has two major advantages over standard dead weight and spring loaded types of breather and relief valves as given below:

It is leak and bubble tight up to set pressure.
It opens fully at 10% over pressure.

These special features of Fluidyne Pilot Operated Breather Valves permit operating pressures close to the maximum allowable working pressure of the tank or vessel. Higher operating pressures reduce evaporation losses thereby reducing production costs. Fluidyne Pilot Operated Breather Valves are manufactured in sizes 2” to 16” and set pressures up to 15 psi.

Fluidyne Breather Valves, also known as direct acting Pressure Vacuum Relief Valves, are types of Relief Valves designed for tank protection. The range includes:-
Pressure Vacuum Valve (PV-Valve)
Breather Valve - Pressure only
Breather Valve - Vacuum only
Breather Valve with Flame Arrestor
All Fluidyne Breather Valves are available with flanged outlets or vented to atmosphere. Pressure/Vacuum Relief Valves are used mainly on bulk storage tanks, including fixed roof tanks with floating covers, to minimize evaporation loss. The Valves prevent the build-up of excessive pressure or vacuum which can unbalance the system or damage the storage vessel. Pressure and Vacuum protection are controlled with weight loaded pallets or springs loaded disc and the required Pressure/Vacuum settings are reached. Sometimes pressure settings require spring loaded disc and the vacuum settings use weight loaded pallet in one device. Fluidyne Breather Valves follow American Petroleum Institute Standard API 2000 or other applicable standard where tanks are generally large volume welded vessels that are built to API 650 standard. In order to accommodate large volumes at low set pressures, these Valves have ports that are larger in area than the inlet or nozzle connection. The low setting required generally require weight loaded disc or pallet and sometimes require spring loaded disc. Because of the above, a Breather Valve requires approximately 20% (minimum) to 100% over set pressure in order to reach full opening of the Valve.
