주요 이점 및 장점
-
Compact Footprint: The small, streamlined design allows these valves to be mounted directly on actuators or within crowded instrument panels where space is at a premium.
-
Two-Way and Three-Way Versatility:
-
Types 167D and 167DS: Standard two-way switching valves for simple on/off or pressure reduction tasks.
-
Types 167DA and 167DAS: Three-way switching valves, ideal for venting downstream pressure or switching between two different pneumatic sources.
-
-
Easy and Accurate Adjustment: Features a simple adjusting screw that allows technicians to set the switching or regulated pressure with precision in the field.
-
Rugged Construction: Built to withstand the vibrations and environmental stresses common in oil and gas and chemical processing plants.
-
Corrosion Resistant Fasteners: Standard construction includes bolting and fasteners treated to resist atmospheric corrosion, ensuring the valve remains serviceable even in humid or coastal environments.
-
Stainless Steel Material Option: For highly corrosive process environments or offshore applications, the 167DS and 167DAS models offer full stainless steel construction for maximum durability.
-
Ease of Maintenance: The simple internal design allows for quick inspection of the valve plug and seat, minimizing downtime during routine instrument maintenance.
기술적 특성
-
Media: Gaseous fluids (Air, Natural Gas, Nitrogen).
-
Maximum Inlet Pressure: Designed to handle standard instrument air and gas header pressures.
-
Temperature Capabilities: Available in configurations suited for a wide range of ambient and process temperatures.
-
End Connections: Typically 1/4-inch NPT for easy integration with standard pneumatic tubing and fittings.
-
Construction Materials: Choice of Aluminum or Stainless Steel bodies to meet site-specific material specifications.
적용 분야
The 167D Series is a fundamental component in pneumatic control logic. It is most often found serving as a “gas regulator” for high-performance pilots or as a switching relay in safety and sequencing circuits.
주요 산업 및 용도:
-
Oil and Gas Production: Providing clean, regulated gas to pneumatic controllers on separators and wellhead skids.
-
Chemical Processing: Managing signal air for control valve positioners and pneumatic relays.
-
Pulp and Paper: Integrated into the pneumatic logic of automated processing machinery.
-
Power Generation: Used in the control air systems for large-scale boiler and turbine dampers.
