E5300-10

Rate of Flow Control Valve

Envotec E5300-10 Rate of Flow Control Valve Maintains a constant flow rate, adjustable, regardless of fluctuations in line pressure. The rate of flow pilot senses the differential pressure across a orifice plate and modulates to keep constant flow rate set on flow regulating pilot. The Orifice Plate Assembly should be installed three to five pipe diameters downstream (outlet) of the Rate of Flow control Valve, and field connected valve and orifice plate with 3/8″ (minimum) copper tubing.
