Epoxy powder coating provides improved corrosion resistance
Description
The Series 62-VNA Constant-Differential Relays serve as air-flow controllers maintaining a constant air purge for each setting of an integral needle valve.
By maintaining a constant-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 constant volumetric rate of flow, regardless of variations in process or supply pressure.
