Neles™ butterfly valve, series BO

Neles BO series butterfly valve is designed for Vacuum Pressure Swing Adsorption plants (VPSA). It is a wafer type, soft seated, high performance, single eccentric disc valve. The valve provides maximal endurance in fast cycling. Additionally, it provides long lasting tight shut off with excellent flow characteristics and high capacity while maintaining the internal tightness even up to 2 million cycles.

Neles™ butterfly valve, series BN

Neles BN series is a cost-effective full bore butterfly valve with a one piece body and an eccentric soft seat. It is specially designed for industrial gas applications featuring long-lasting tight shut-off capability, excellent flow characteristics and long service life. BN series butterfly valve is also used in control applications.

Neles™ butterfly valve, series BH

Neles lever valves are designed to air separation unit air inlet shut-off valve. They feature self-locking safety design for a specified differential pressure. The lever arrangement provides valve operation with low friction. The sealing sections are not subjected to abrasion wear, resulting in extremely low torque level.

Neles™ butterfly valve, series BWX

Neles BWX series butterfly valve has been especially designed for use in cryogenic applications with high quality CrNi steel. Testing of the valve includes cold shock test and it can be used for gaseous and liquid oxygen, LNG, nitrogen, hydrogen and other cryogenic fluids.

Neles™ butterfly valve, series BW

Neles BW series metal seated double eccentric disc valve is designed for both control and tight shut-off in severe service. Multiple seat options makes it well suited for the refining, power, petrochemical and chemical industries. The BW series provides extended operational life in high cycle, high temperature and abrasive applications.
