New Simplified Directional Control Valves for Hazardous Environments
Industries operating in hazardous environments such as the oil and gas industry inherently depend on reliable products operating in critical settings, while requiring the need to maintain safety and strict compliance. Listening to the voice of the customer is crucial in the design of simple solutions to mitigate the trifecta related to the complexity of maintaining multiple part numbers, operating in multiple environments, all while maintaining multiple certifications. One such example comes from the team at Parker Hydraulic Valve Division. Over the years, the team’s design engineers have worked closely with these customers on the continual improvement of the product portfolio. The latest innovation is the new D1VW*ER (NFPA D03 / NG06 / CETOP 03) directional control valve. The team has focused on complexity reduction for its end-users while maintaining all the expected quality and performance Parker directional control valves have become known for.
Versatile and flexible design
Indexable solenoid connector
With three horizontal positions and a vertical option for wiring installation per solenoid, electrical connections have become more adaptable. This modularity allows end-users to have more standardization by carrying fewer overall part number combinations. Additionally, usage of expensive explosion-proof fittings can be reduced. These adjustments can be made while still maintaining the tri-rated explosion-proof certifications.
Tri-rated hazardous location/explosion-proof certifications
The multi-ratings provide needed coverage and confidence in usage across the globe. These ratings include:
- ATEX
- CSA/UL
- IECEx
Expanded temperature range
Based directly on customer feedback, temperature limits have been expanded to now carry an operating temperature range of 70 °C down to -54 °C.
The expanded versatility is another nod to global usage needs, particularly in extremely cold locations in the Oil & Gas industry.
Parker Tracking System (PTS) QR code
End-users now have instant access to both critical information and certifications, when scanning the laser-etched QR code. No longer will there be wasted time and headaches trying to find various needed documentation. For example, all ATEX, CSA/UL, and IECEx certs are accessible and maintained current.
Additional attributes
After further input from our customers and design engineering team, other attributes of the D1VW*ER include:
- Available with 24 VDC and 120 VAC rectified coils.
- Extended and covered manual overrides come standard.
- Surge suppressor diode for 24 VDC coil comes standard.
Target applications
Although these valves can be used in countless hazardous environments, the design was heavily influenced by the needs of the Oil & Gas industry. Some targeted focuses are shown in figure 1 (below).
The D1VW*ER expands the offerings of Parker HVD hazardous rated valves, which also include:
- Directional Control Valve (Mobile) – L90 (ATEX)
- Servo BD15/BD30 (ATEX, CSA/UL, IECEx, UKEX)
- Proportional – FB*EE
- Proportional – FV*EE
