Tyco Valves & Controls has released its large bore triple offset valve. The RMI Dubex butterfly valve features a resilient seat and disc seal. Supported by in-depth test data and calculations, the valve is approved to KIWA, KTW, PED/CE and ATEX standards. Available in diameters from 150mm which uses a single piece disc, sizes up to 4000mm can be specified for large diameter applications.
The standard single piece disc design uses a rubber seal on the valve disc, which then fits to a metal seat within the valve body. Diameters over 2000mm use a flow-through disc design which balances disc stiffness and flexibility to ensure the valve disc does not suffer damage from water hammer, but is also stiff enough to close when under pressure from the pipeline media.

Designed for versatile use, the construction of the RMI Dubex valve can be adapted depending on the size and application. Due to the triple offset design the valve has a non-rubbing seat/disc contact extending the valve life cycle.
A dry shaft option can also be designed which protects critical moving components for improved wear characteristics. It is specifically designed with pump station, wastewater effluent treatment, circulating water systems, desalination and cooling water systems applications in mind.
