High Performance Double Union Ball Valve - JBBV-104 Double Block & Bleed Monoflange Valve –

Block & Bleed Monoflange

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.
