Imperial Valve is a relatively young company and therefore has a short history. The company was founded in 1992 as a subsidiary of De Gidts & Feldman. The product range of Imperial Valve consist of double block & bleed valves, manifolds and instrument enclosures. Initially, the complete range of products of Imperial Valve was manufactured in Winsford, UK. Since 2004 the production has expanded considerably, and production sites are now situated in different locations in Europe. Over the years, Imperial Valve kept expanding and the company has gained a strong market position. In 2010 Imperial Valve B.V. started to form an international network of carefully selected distributors, to meet the growing demand for export. The international distributors are situated close to the customers, speaking their language and understanding their local challenges.

DOUBLE BLOCK & BLEED MONOFLANGE
DESCRIPTION
The Double Block and Bleed Monoflange represents a true technical and economical innovation. Differently from the old system composed by big size block valves, safety and on-off valves, draining and sampling, these monoflanges allow to reduce costs and spaces. The monoflanges can be realized in traditional AISI 316 L as standard or exotic materials when required. They have compact dimensions with consequent reduction of assembling costs.
FEATURES
>> Rolled stem threads prevent galling
>> Stem threads are completely isolated from the process
>> Stem packing with graphite rings for bubble-tight seal
>> Bolted bonnet strength and reliability
>> Stem tip construction: non-rotating self-centering
>> Flange gasket seal ensures a bubble-tight between body and bonnet
>> Backseat design provides secondary stem sealing and prevents stem blowout
>> Adjustable gland flange allows easy access to the packing gland and packing adjustment for an effective stem seal
>> Robust handwheel painted
>> Firesafe to BS 6755 PART. 2
>> Pressure rating up to 6,000 PSI (413 bar)
>> Temperature rating: (Grafoil) -54°C / +510°C (-65°F / +950°F)
