Mechanical, Heavy Duty, Automatic Flow Control Valve
FOR POSITIVE DISPLACEMENT PUMPS ONLY
This valve will control the air flow rate to ±5%of the set flow rate over a wide pressure differential.It is the best commercially available mechanical vacuum flow controller. The unit operates by use of two diametrically opposed springs and a diaphragm that controls the valve opening.Depending upon pump capacity,flows between 0.5 to 10 CFM can be controlled by increasing or decreasing the spring tension with a wing nut found under the protective spring cover housing.Once set,the control valve will maintain a constant flow,±5%,up to the capacity of the pump.This valve is a full Flow Controller not a “Flow Regulator ” or adjustable orifice commonly found in the industry.Because the MCV-260 uses no make up air,nor “bleed-in ” air to control the flow rate,,the total volume of air sampled equals the total volume of air exhausted.This is ideal for applications requiring a Gas Meter to be hooked up to the exhaust (pressure application)of the sampler for totalizing the volume of air sampled.
