XC Construction
Alco Valves Group Ltd, part of the international engineering firm Graco, have enhanced its double block and bleed (DBB) valve offering with the release of the XC valve range. The new design features of the interchangeable DBB range, represent a forward-thinking approach by gaining the ability to offer customers highly engineered products with radically reduced lead times at competitive prices.

When fully assembled the XC valves are unlike any other DBB valve on the market. However, the Alco Research and Development team were able to challenge the conventional methodology of DBB design to create an innovative interchangeable valve solution. The XC compact design allows the centre module of the valve to be manufactured, assembled, tested and stocked without fitting the end connections, before the point of order placement. This means drastically reduced lead times for the benefit of the customer.

Alco Valves have invested heavily in the latest state of the art CNC machinery and other advanced manufacturing equipment which has supported the initiative to provide expedited deliveries for highly complex DBB technologies. This outstanding level of investment ensures that the company achieves operational excellence when meeting customer requirements.
