The OCV Series 120 Rate of Flow control valve is designed to control or limit flow to a predetermined rate, regardless of fluctuations in down stream or upstream pressure.

• Self contained, including the differential-sensing orifice plate and pilot.
• Flow rate is field adjustable (within orifice bore range)
• Extra-sensitive-differential pilot specifically designed for Rate-of-Flow application.
• Works equally well on all types of clean, non-abrasive liquids.
