NOVA SWISS block valves with venting (Block and Bleed — BBV) as well as double-block valves with venting (DBV) provide maximum safety in confined spaces. Their design allows measuring instruments and/or pressure gauges to be disassembled in an unpressurized state during running operation. Additional features include a reduction of potential leakage points and the number of screw connections to a minimum. The BBV is available in 1/4" and 3/8" versions, the DBV in 1/4", 3/8" and 9/16". Some of our block valves are also available in custom designs on request.
