أجهزة التوجيه من سلسلة Fisher 61 | تحكم عالي الدقة لأجهزة تنظيم الضغط التي تعمل بواسطة الطيار

الفوائد والمزايا الرئيسية

• 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:

  1. Type 61L (Low Pressure): The standard for general low-pressure utility service.

  2. Type 61LE (Low Pressure, Wide Proportional Band): Optimized for systems where a slower, more stable response is needed to prevent hunting.

  3. 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.

الخصائص التقنية
