Những lợi ích và ưu điểm chính
-
Highly Configurable for Diverse Applications: The 61 Series is available in multiple styles to match specific system requirements. Whether the application requires low-pressure sensitivity or high-pressure durability, there is a 61 Series construction designed for the task.
-
Proportional Band Flexibility:
-
Type 61L (Low Pressure): The standard for general low-pressure utility service.
-
Type 61LE (Low Pressure, Wide Proportional Band): Optimized for systems where a slower, more stable response is needed to prevent hunting.
-
Type 61LD (Low Pressure, Narrow Proportional Band): Designed for applications requiring ultra-fast response and tight accuracy.
-
-
High and Extra-High Pressure Ranges: For transmission and high-pressure industrial headers, the Type 61H and 61HP (Extra-High Pressure) versions provide the structural integrity needed to manage heavy-duty pressure reduction.
-
Standard and High-Temperature Materials: Depending on the process environment, these pilots can be equipped with specialized elastomers and seals to handle standard gas temperatures or extreme high-temperature steam and process heat.
-
Integrated P594-1 Filter: To ensure the longevity of the pilot’s internal orifices, every 61 Series pilot includes a Type P594-1 filter as standard. This prevents pipe scale and debris from interfering with the pilot’s sensitive control mechanisms.
-
Efficient Use of Operating Medium: The 61 Series is designed to use the existing inlet gas pressure to operate the main valve, eliminating the need for an external pneumatic air supply in many installations.
-
Ease of Service: The pilot is designed to be easily accessible for spring changes or maintenance without necessitating the removal of the main regulator from the line.
