Description
The Maxitrol MR510 modulator/regulator valve is part of the Selectra line of M/MR Series control valves. It integrates both modulation and pressure regulation into one compact unit — eliminating the need for separate regulators in many burner systems. Designed for negative‑pressure (pull‑through) burner systems, the MR510 smoothly varies downstream gas pressure (flame level) in response to input voltage, while maintaining stable control across low and high fire conditions via its dual‑spring mechanism. It’s ideal for atmospheric, direct‑fired, infrared, or process heating systems where precise, non‑fluctuating temperature control is required.
