| Blackhall - New Offshore "Anti-Seize" Divertor Valves (350mm to 600mm).............
Valve specialists Blackhall Engineering are now using Armoloy surface coating on their recently developed range of large bore “anti-seize” diverter valves (350mm to 600mm) that are being used on offshore oil platforms. The coating is an integral part of the high performance properties of the new valves, which have a product life requirement of 25 years. Both the valve plug and internal surfaces of the main body are treated with the Armoloy process which creates a unique thin dense coating which permeates and bonds with the host metal to create a surface that is smooth, hard and extremely resilient. This provided Blackhall with the surface assurance properties that they were looking for in the highly corrosive and abrasive environments in which the valves operate. “We began trialling Armoloy on small components,” commented Paul Taylor, Engineering Development Manager at Blackhall, “and we quickly found that it was delivering the friction and corrosion resistance we were looking for – it has become the natural choice for us.” The diverter valves have to carry a mixture of oil, sea water, sand and abrasive debris under pressure, and they are normally positioned just under the main rig platform. Blackhall specialise in bespoke, high-performance valves that have often been designed to operate in a variety of “challenging environments.” Their diverter valves are based on a unique anti-seize design that was originally developed by the company over 40 years ago and has now been evolved to operate in the oil and gas sector. At around 3 tonnes each, the valves are much lighter than existing designs that are traditionally used on platforms and the company sees considerable potential for future growth. It is also in discussion with Armoloy about further advanced applications.

Large Gate Valves For The Port of Newport. The first of 3 Hydraulically operated 60" Bore Wedge Gate Valves has been fully refurbished and is now operational at Newport Docks South Wales. The Valves were originally manufactured by J Blakeborough & Sons, Brighouse in 1963. The work for Associated British Ports, has been done in conjunction with Qualter Hall & Co Ltd in Barnsley. The repair of the next 2 valves will be completed by the end of the 2009. Before & After pictures can be seen on the right. |

| Two enormous Larner Johnson Valves for America have passed final inspection and are ready for shipping to the United States of America. Delegates from America visited our works last week to carry out a full inspection of the valves and witness the Hydrostatic pressure test. Each of the 60” Bore valves weigh in at a massive 17 tons. The valves will be installed at the Ashokan Reservoir which is located at the Eastern End of the Catskills Park in the Catskills mountains, New York State. It is New York Cities deepest Reservoir being over 190 Feet (58.5m) deep at its deepest. When installed 60% of New York City's water will pass through the valves . This is the completion of the first part of the order for four Valves. The second two valves are currently being manufactured and will be ready for shipping later this year. |

| All Systems Go at The Queen Mary Reservoir
The two 1600mm series 3200 Submerged Discharge valves, recently supplied to Thames Water have been successfully commissioned. The Valves at the Queen Mary Reservoir near Staines have been installed so that the water level in the Reservoir can be dropped quickly, in the event of an emergency situation. An almost identical system is to be installed at The King George V1 Reservoir. Blackhalls have just received the order for the two Submerged Sleeve Discharge Valves. The Valves are 1.2mtr Bore and stand 8 metres tall. Each Valve has a flow capacity of 7 Meters a second. |

| Blackhall Engineering have just successfully repaired and commissioned 2 -33" Bore Larner Johnson Scour Valves original manufactured by Blakeborough valves in 1949. The Work was carried out for South Staffordshire Water PLC at Blithfield Reservoir near Abbotts Bromley in Staffordshire. The valves had become very tight to operate, so an internal inspection using an endoscopic camera was carried out which identified the problem as excessive corrosion/wear on the internal operating gearing. Both Valves were too big to be removed from the valve chamber so a specially designed lifting frame was manufactured and installed to allow the valves to be removed from the pipeline and dismantled in the valve chamber. Both the valves were fully dismantled and thoroughly cleaned. A new internal gear was manufactured and installed, the valves re-assembled and re-installed into the pipeline.

| Blackhall Design & Manufacture 22 Tonne Valves for Thames Water
Two 1600mm Series 3200 Submerged Discharge Valves are the largest of their type built to-date by Blackhall. The huge valves, each weighing more than 22 tonnes, and standing 13 metres tall were designed for a maximum flow capacity 13 cubic metres (tonnes) a second. They will be installed on the Queen Mary Reservoir, facilitating the rapid draw down of the reservoir water levels in an emergency situation. |

| Blackhall are pleased to announce the acquisition of all the assets, goodwill and intellectual property of Shaw Son & Greenhalgh Ltd and Taylor Valves Ltd.
The Brand names and personnel will remain unchanged. Taylor Shaw Steam products will be manufactured at a site in Huddersfield, and the Shaw 'Haz Chem' Valve will be manufactured at the Brighouse site. James Blackhall, Managing Director comments "It made perfect sense as the niche of the product fits extremely well with the Blackhall ethos". Sales contacts for all products will remain unchanged, as will aftersales support. |

| Back Home to Brighouse after 83 Years.
A large valve first manufactured in 1924 at the former J Blakeborough & Sons Works, has recently been taken out, re-furbished, re-installed and successfully commissioned at the Llwyn-on Reservoir, near Merthyr Tydfil in the Brecon Beacons, South Wales. The 36” Bore Larner Johnson Valve is one of a pair of valves used as emergency draw down valves, enabling water flowing at up to 8m3/sec, with velocities reaching up to 16m/second, to be released from the reservoir. Operations Director, David Richmond said “It was a real challenge just to get the valve out of the reservoir outlet tunnel”. The valve, which weighs 7 Tonnes, had to be manoeuvred a quarter of a mile down the tunnel on a specially designed track. The valve was then returned to the Bradford road works to be fully refurbished, before returning to Wales, ready for another 83 years service. Blackhall Technical Director, John Lewthwaite said, “The valve was in amazing condition despite its age, however, a number of the major components had to be replaced. This didn’t cause a problem, as we hold all of the original Larner Johnson drawings, first produced by the Blakeborough drawing office dating back to the late 1900’s”. Blackhall bought the intellectual property rights to continue the manufacture of the Larner Johnson Valve in the late 1980’s. James Blackhall, the Managing Director said “It is a very exciting time for the company. We have recently been successful in winning a number of other large projects from various water utility companies, both in the UK and overseas. One of these such projects is for 4no 72” Bore Larner Johnson Valves, which are currently in production. Each of these weighs 18 tons, and when installed at the Catskills Reservoir’s, will supply 60% of the water for New York”. |

| An example of Blackhall's product quality and longevity, is a valve, first manufactured well over 25 years ago, being returned to an oil refinery in as good as new condition after refurbishment.
The valve, an Angle Pattern Automatic Recirculation Valve, was first machined, built and tested by Bruce Lewis (pictured), and has again been lovingly restored to it's original high specification by him. Bruce is our longest serving employee, and having celebrated his 40th year with Blackhall in 2006, continues in the company's commitment to providing a world class service, and continuity of expertise in valve applications. |
