Những lợi ích và ưu điểm chính
-
Compatible with Multiple Main Valves: One of the greatest strengths of the 6358 and 6365 Series is their universal compatibility. They are designed to work seamlessly with various Fisher main valves, such as the Type 1098 and Type 98, allowing for standardized maintenance and parts inventory across a facility.
-
Low Buildup for Maximum Protection: The 6358 Series specifically excels in minimizing the pressure buildup required to move the main valve to its full open position. This ensures that the system is protected immediately upon reaching the setpoint, preventing dangerous overpressure conditions in sensitive downstream piping.
-
Adjustable Gain for Tunable Performance: These pilots feature an adjustable gain (or proportional band) capability. This allows technicians to fine-tune the speed and stability of the valve’s response to match the specific dynamics of the process loop, effectively eliminating “hunting” or pressure surges.
-
Gas and Liquid Service Versatility: Unlike many pilots that are limited to a single phase, these series are built to handle air, natural gas, propane, water, and various industrial oils. This multi-media capability simplifies the selection process for complex process plants.
-
Rugged Construction: Built to withstand the harsh environments of oil and gas skids, these pilots utilize high-strength materials and corrosion-resistant coatings to ensure reliable operation in outdoor and coastal locations.
-
Precise Setpoint Retention: The high-quality spring and diaphragm combinations used in these series ensure that the relief setpoint remains stable over time, reducing the need for frequent recalibration and field adjustments.
-
Ease of Field Service: The pilots are designed for quick disassembly, allowing for the inspection of orifices and seals without requiring specialized laboratory tools.
