Datasheet BD damper valves Datasheet FSV Full Bore Datasheet FSVN Necked MID have supplied key components to Drax power for their new biomass project. The biomass is taken out of the bottom of the boiler distribution system through 30 of our 1750×800 slide valves, and the air displaced during loading of the silos is vented through our 4 off 2m diameter butterfly damper valves and into a dust filtration system which has more butterfly damper valves, this time…
Datasheet TWA rotary valves It’s the biggest TWA rotary valve we’ve made to date. The valve has all the features you would expect from the TWA range- wear resistant rotor, adjustable liner, leak free mechanical seals and can be made “good as new” when worn by replacing the liner and rotor wear parts. The rotor turns concentrically to a tolerance of only 0.1mm and the gap around this to the liner is only 0.3 to 1.0…
Datasheet BD damper valves We’ve already made some metal seated damper valves to go under the filters on the boiler distribution system. These are similar but they have a requirement to have a tight seal as the dome silos are nitrogen blanketed. The valves are designed to be closed, locked, the seal inflated and used as a platform to change the filter bags. The custom moulded inflatable seat keeps the nitrogen out and has been tested to hold…
Datasheet BD damper valves We’ve already made some slide valves to go under the boiler distribution system. At the top of the silos there are some dust filters to clean the displaced air. Occasionally the filter media in these needs to be changed so we’ve made some 2.2m diameter butterfly damper valves that can be closed, locked and used as a safe working platform for the personnel changing the filter media. They’re manually operated by big worm-wheel gearboxes…
Datasheet FSV Full Bore Datasheet FSVN Necked Drax Power are big news at the moment, converting their coal fired boilers to wood biomass generation with Shepherds Construction. They have had 24 MID slide valves installed on their test plant working successfully for a few years. For their main conversion project, they chose MID as the existing valves have required no maintenance or repair work since installation. The 30 off 1750 x 800 valves are under the boiler distribution system,…
Datasheet FSV Full Bore Datasheet FSVN Necked We’re just finishing off an order for 31 large stainless steel valves handing fertiliser in a dockside handling plant in Estonia. They’re all screw jack operated and the large 1500×800 valves have an encoder switch so the plate can be positioned anywhere in the stroke to control the flow rate. They’re all designed to work down to a chilly -32°C. Careful selection of materials, lubricants and electrics allow us to do…
