Foot valves

Bottom loading has fast become standard in Europe and many other countries. The foot valves can be balanced or unbalanced, requirements differ from market to market and are pneumatically operated. Each foot valve is pneumatically connected in sequence to the pressure/vacuum valve on that compartment. Talking points are reliability and serviceability.

Vapour recovery valves

Pressure/vacuum valve for vapour recovery

When bottom loading, it is vital to open the compartment sequentially ahead of the foot valve in order to allow air/vapours out as the product enters the compartment. In order to follow the VOC directive it is necessary to collect the vapours and return them to the gantry. At the same time, each compartment must be secured against ignition by a flame arrester.

Also during transport and discharge the compartment must be able to “breath” so the pressureless tank remains without overpressure and vacuum.

A pressure/vacuum vapour recovery valve with an integrated flame arrester will solve all of the issues above and this is what we can offer.

Ball valves

Stop or two-way valve, three sizes, five different flanges, manually or pneumatically operated in combination with many other features makes Gard ball valves the ideal choice for any petroleum installation. High flow rate and low contamination
The stop valve ball is manufactured with a straight bore to minimise flow resistance and product residues, an important feature that reduces contamination of sensitive products.

Highest quality
Carefully designed and well tested in combination with only the best materials and high precision manufacturing ensures a long lasting and trouble free life.

The Gard Ball Valve
The Gard Ball Valves are manufactured in three sizes 2-, 3- and 4-inch and each size is available with different flanges or combination of flanges. The valve can be manually operated or fitted with a pneumatic acturator.

The stop valve is normally delivered with a chromium plated brass ball with a straight bore to minimise flow resistance and contimination. This valve can also be ordered with a tefol coated aluminium ball for jet fuel installations. The two-way valve comes with a teflon coated aluminium ball.

Both valve casings are made from extruded aluminium. The stem assembly is made of brass and all steam seals can be serviced without removing the valve. All seals are made of teflon or high quality FPM to withstand all commercial petroleum fuel grades.

There are five different flanges available in steel and aluminium. The same flanges are used for the stop valve as for the two-way valve with the exception of the two-way valve inlet that in some cases requires an adaptor piece. The threaded
holes on the TW-flange are lined with helicoil inserts, M10 for the 3-inch valve and M12 for the 4-inch. The 4-inch aluminium flange is only for welding.

Fitted between the solenoid valve and the actuator this extra pneumatic outlet provides a simultaneous link to other pneumatically controlled equipment.

Service friendly
When removing the flanges for service or installation the ball and the main seals are kept in place by the retainer ring that locks to the valve casing with a bayonet catch - much appreciated time saving design. The handle and stem unit can easily be removed for service without dismantling any other
parts of the valve.

Sampling valve

The Wennstrom sampling valve is similar to a normal foot valve with an important exception: no loading is carried out through the valve. There are two versions; one is pneumatically controlled, the other is opened via a wire.

Dimensions: DN20

Versions of the sampling valve Item no.
R-20 LYP pneumatic 16-3069
R-20 LYM mechanical 16-3070
