Camerons re-designed ENTECH DRV-BN nozzle check valve
introduces a modularity that allows for customized solutions,
in-field reconfiguration and a consistent spring force
mechanism for quick and easy maintenance.
The DRV-BN is the newest large-bore addition to Camerons
valve portfolio. By combining a modular approach with an
improved quality of casting, the DRV-BN supports customization
to any specific service condition as well as on-site
re-configuration should flow changes occur over time.
The single coil spring is an inexpensive and simple, yet highly
effective, maintenance solution. The disc is
shaft-supported for a perfect disc-to-seat alignment in all
installation conditions. The design incorporates a
weight-saving annular design which aids in response time to
flow fluctuations and wear resistance.
The DRV-BN also represents a significant step forward in terms
of the fluid dynamics related to ENTECHs high flow
coefficients and top-class axial design. These features help
the valve reduce operating costs.
As a complete offering, the ENTECH DRV-BN and the smaller
bore DRV-Z represent a technically flexible and economically
ideal solution for back flow prevention and protection of
critical equipment. Both are ideal for applications where
minimal pressure losses are essential, such as compressor
stations and gas facilities, pump and wellhead
injection plants, water distribution and treatment, tank
storage and power plants.
