    Since 1930, ENTECH nozzle check valves have provided reliable backflow prevention for the oil, gas, water and process industries.

    Beginning in 1972, ENTECH has served the nuclear industry with nozzle check valves for containment and commercial process.

    The ENTECH nozzle check valve is designed to meet the criteria of conventional check valves by allowing forward flow under normal conditions, opening easily, firmly backseating at low velocity and closing on reverse flow with minimal seat leakage.

    The ENTECH nozzle check valve meets these basic requirements and incorporates these additional features:

    The ENTECH nozzle check valve is aligned with other Cameron products, leading the field in pipeline and gas production, offshore, onshore, sub-sea, refining and industrial processing.

    Non-slamming - valve closes prior to reverse flow

    Short stroke length reduces closure time and minimizes water hammer

    Metal-to-Metal seating

    Conical seating surface is self-aligning and provides tight shut-off

    Minimum pressure loss with excellent dynamic performance

    Spring loaded disc design allows mounting in any orientation

    No scheduled maintenance

    DRV-Z

    The DRV-Z Nozzle Check is a small bore valve designed for use in piping systems from 1 in. (25 mm) to 10 in. (250 mm) diameter. This size range allows the use of a simple, streamlined, in-line check design which is quick to respond to changes in velocity.

    The DRV-Z design also provides: Non-Slam Closure

    Metal Seating

    Extremely Quick Closure

    Spring Loaded disc design allows mounting in any orientation

    Low Pressure Loss

    No Scheduled Maintenance

    Sizes and Ratings Size 1 in. (25 mm) through 10 in. (250 mm)

    ANSI/ASME Classes 150 through 2500

    API 3000 through 10,000

    Face-to-Face API 6D, Manufacturers Standard, DIN Standard

    End Connections ANSI/ASME flanges are standard,weld end or other flange end configurations can be provided upon request

    Other sizes and pressure classes will be considered upon request

    NON-SLAM, NOZZLE CHECK VALVEPRODUCT OFFERING

    The DRV-B(O) Nozzle Check is a large bore valve for use in compressor and pumping stations from 12 in. (300 mm) through 36 in. (900 mm) diameter. In this size range ENTECH incorporates the use of an annular ring design which outperforms other nozzle check valve designs. By utilizing the doughnut shaped annular disc, ENTECH Nozzle Checks are able to minimize the weight (mass) of the disc and has the ability to go from fully open to fully closed in a fraction of a second.

    The DRV-B(O) design also provides: Non-Slam Closure

    Metal Seating

    DRV-BK

    NON-SLAM, NOZZLE CHECK VALVEPRODUCT OFFERING

    The DRV-BK utilizes the same design concept and features and benefits found in ENTECHs DRV-B(O) design. The only difference is that the DRV-BK is a compact design thus it has shorter Face-to Face and is lighter weight.

    The DRV-BK design also provides: Non-Slam Closure

    Metal Seating

    Extremely Quick Closure

    Spring Loaded disc design allows mounting in any orientation
