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.
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.
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.
