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

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

The ENTECH nozzle check valve is designed to meet thecriteria of conventional check valves by allowing forwardow under normal conditions, opening easily, rmlybackseating at low velocity and closing on reverse owwith minimal seat leakage.

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

The ENTECH nozzle check valveis aligned with other Cameronproducts, leading the eld in

pipeline and gas production,oshore, onshore, sub-sea,rening and industrial processing.

Non-slamming - valve closes prior to reverse ow

Short stroke length reduces closure time andeliminates water hammer

Metal-to-metal sealing Conical seating surface is self-aligning and

rovides tight shut-o

Minimum pressure loss withexcellent dynamic performance

Spring loaded disc design allowsmounting in any orientation

No scheduled maintenance


APPLICATIONS

PRODUCT OFFERING

DRV-Z

The DRV-Z Nozzle Check is a small bore valve designed for use in piping systems from 1 in. (25 mm) to10 in. (250 mm) diameter. This size range allows the use of a simple, streamlined, in-line check designwhich 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

PRODUCT OFFERING

The DRV-B Nozzle Check is a large bore valve for use in compressor and pumping stations from 12 in.(300 mm) through 68 in. (1700 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 doughnutshaped annular disc, ENTECH Nozzle Checks are able to minimize the weight (mass) of the disc and hasthe ability to go from fully open to fully closed in a fraction of a second.

The DRV-B design also provides:

Non-Slam Closure
