ประโยชน์และข้อดีที่สำคัญ
-
Sensitive Response to Pressure Changes: The oversized diaphragm-to-orifice ratio allows the 66 Series to detect and correct very small pressure deviations. This is critical for low-pressure systems where maintaining a stable setpoint is essential for safety and efficiency.
-
Tank Blanketing Capability: The 66 Series is an excellent choice for nitrogen padding or blanketing. It maintains a constant, positive pressure in the vapor space of a storage tank, protecting the contents from atmospheric contamination and preventing the tank from collapsing during pump-out.
-
Seat Protection and Shutoff Capability: The internal design provides robust seat protection that prevents damage from high-velocity flow or minor debris. This protection is achieved without sacrificing the regulator’s ability to provide a tight shutoff, which is necessary to prevent pressure creep in dead-end systems.
-
Vacuum Service Versatility: Beyond pressure reduction, the 66 Series is available in specialized vacuum constructions:
-
Vacuum Regulator: Controls the level of vacuum by throttling the flow between the vacuum source and the process.
-
Vacuum Breaker: Protects tanks and piping from collapse by admitting air or inert gas when the vacuum level exceeds the setpoint.
-
-
High Control Accuracy: The direct-operated architecture eliminates the complexity and potential lag of pilot systems, providing a linear and predictable response to load changes across the entire operating range.
-
Application Flexibility: With various spring ranges and material options, the 66 Series can be tailored to handle a wide variety of industrial gases and environmental conditions.
