المزايا التقنية الأساسية
-
Rapid Field Adjustments: Set point, zero/span calibration, and switching between direct and reverse action can be performed quickly without specialized tools, reducing downtime during maintenance or process shifts.
-
High Vibration Resistance: The simple internal design and low-mass components allow the controller to maintain accuracy and stability even in high-vibration plant environments.
-
Environmental Protection: The durable plastic housing is engineered to withstand corrosive atmospheres, making it ideal for the harsh salt spray of offshore platforms and the chemical vapors of processing plants.
-
EPA-Compliant Efficiency: The advanced relay and nozzle design limits steady-state air consumption to as low as 0.09 m³/hr (3.5 scfh), easily exceeding the strict 6 scfh emission requirements set by the US Environmental Protection Agency (EPA).

التطبيقات والقطاعات الصناعية
The 4195K is the preferred choice for reliable, non-electronic pressure control across several heavy industries.
-
Oil and Gas Production: Monitoring and controlling separator or wellhead pressure, especially in remote areas where minimizing gas consumption is a priority.
-
Chemical Processing: Regulating pressure in corrosive production loops where electronic instrumentation might be prone to failure.
-
Offshore Platforms: Providing visible local indication and control in compact, salt-saturated environments.
-
Power Generation: Localized pressure control for auxiliary steam or water systems requiring rugged, stand-alone pneumatic logic.
