Aval is a supplier of Atex approved low pressure and vacuum equipment, including flame arresters, regulators and control valves, tank gas blanketing valves and pilot operated vent valves. Aval is the exclusive UK distributors for Cashco, Kaye MacDonald, Sensiflo and Valve Concepts equipment, and have also been the exclusive UK agents of Lupi conservation vents and flame arresters since 1988.
The commitment to our customer does not end once we have delivered the goods; we offer a comprehensive Field Services program that offers maintenance programs tailored to suit individual customer requirements. Requirements for industry to comply with higher safety standards and meet increasingly stringent air quality regulations call for advanced technological solutions.
Aval has continually met the challenges of environmental and safety standards by expanding its vapor safety products to serve storage tank facilities, offshore drilling and production, oil and petrochemical refineries, chemical processing plants, pharmaceutical manufacturing facilities, automotive and industrial production, pulp and paper processing, landfill and sewage treatment, biofuel production and all other industries in the ever increasing environmental vapor control process.

The element inside the housing provides an extinguishing barrier to the ignited vapor mixture by absorbing heat from the flame.
The Model 7A00 is used as an independent safety system to ensure explosion protection.
7A00 flame arrestors are designed on the principle of "quenching gap".
The crimped SST metal element allows vapor to pass through in order to allow a vessel to breath, yet prevents the propagation of a flame from the exposed side to the protected side.
The Model 7A00 is designed, manufactured, and tested according to Directive 2014/34/EU (ATEX95) and ISO 16852.

The Model 5100 has a pilot operated pressure side which permits tank operating pressures closer to the maximum allowable operating pressure.
This provides a more positive control over vapor generation inherent in fluids with higher vapor pressures.
The vacuum side of the vent is weight loaded and allows intake of air when necessary to remain within the vacuum design rating of the tank.
Body & Weather Hood Material: Available in Aluminum, Carbon Steel or 316 SST.
Numerous Sizes.
Available in Sizes 2" through 12".

When the tank pressure reaches the setpressure of the pilot, the pilot assembly opens eliminating the additional downward force on the pallet assembly.
The "full" tank pressure pushing upward on the palletassembly will cause the main valve to open.
Full flow willbe achieved at no more than 10% overpressure.
Oncethe overpressure is relieved the pallet assembly will reset providing a tight seal.
Available in Sizes 2" through 24".
CS & SST vents have Raised Face Flange, Aluminum ventshave Flat Face Flange to mate with ASME150# flange connections.

Internal trimdesign allows the same basic unit to cover a broad range of pressure settings.
Performance approaches that of competitive pilot-operated designs in the basic construction.
Applied primarily in clean gaseous or liquid services.
Truly a "DO-ALL" pressure regulator.
The "DO-ALL" design allows application of all types of clean fluids.
Designed primarily for gaseous and liquid service applications where excessive cavitation is absent.
Excellent for atmospheric industrial gases - GN2, GOX, Ar, He, H2, CO2 - as well as a natural gas regulator.

The Model 1078 is a pilot-operated valve, specifically designed to reduce blanketing gas losses on lowpressure storage tanks.
The simple design, increases reliability and lowers maintenance cost.
On many low-pressure storage tanks the operating range is very low, which makes blanketing and venting system selection/design a challenge for the engineer.
The Vacu-Gard makes the job much easier.
First, the Vacu-Gard set point definition is where the blanketing valve closes bubble tight.
Second, the Vacu-Gard has a wide range of available settings, from vacuum to 14 psig, that make proper selection easier.
