Series Pressure Reducing Valve For Pilot Regulators are Pilot operated for control of gas & air pressure. In single stage, pressure reduction can be achieved very precisely up to 1/10th of the inlet pressure. Pilot operated Regulator gives very precise downstream pressure and very low fluctuation. They are extensively used as active and monitor control in series for Natural Gas Pressure Reducing System. Valve has very high flow Capacity and very precise regulation with the help of Pilot.
