Description
The Series 62-VNA C***tant-Differential Relays serve as air-flow controllers maintaining a c***tant air purge for each setting of an integral needle valve.
By maintaining a c***tant-differential pressure drop across a built-in needle valve (for any flow setting up to 2.1 cu. ft. of air per hour), Series 62 Relays ensure a c***tant volumetric rate of flow, regardless of variati*** in process or supply pressure.
