Key Benefits and Advantages
-
Versatile Application Range: The 6350 and 6360 Series are engineered to be modular. They can be mounted on various Fisher main valves to create a tailored solution for either reducing downstream pressure or maintaining upstream backpressure.
-
Adjustable Gain for Tunable Performance: These pilots feature an adjustable gain (proportional band) capability. This allows operators to fine-tune the speed of response and stability of the entire regulator assembly. By adjusting the gain, you can eliminate system oscillations or “hunting,” ensuring a smooth and steady pressure profile even under rapidly changing flow conditions.
-
Multi-Media Compatibility:
-
Gas Service: All models within the 6350 and 6360 Series are fully compatible with natural gas, air, propane, and other non-corrosive gases.
-
Liquid Service: With the exception of the Type 6351, these pilots are designed for liquid applications, including water and industrial oils, providing the same high level of precision as they do in gas service.
-
-
Easy Valve Plug Maintenance: The internal architecture of these pilots allows for quick access to the valve plug and seat. Maintenance can be performed efficiently in the field, reducing the time required for routine inspections and ensuring the pilot remains in peak operating condition.
-
Precise Sensing and Registration: Whether using internal or external pressure registration, these pilots are designed to provide a highly accurate signal to the main valve. This results in minimal pressure droop and exceptional setpoint stability.
-
Rugged Construction: Built to withstand the rigors of industrial environments, the 6350 and 6360 Series utilize durable materials that resist wear and atmospheric corrosion, ensuring a long and reliable service life.
