Back Check Valve Assembly Function
The 41638 back check valve assembly is identified as a replacement fluid-control component in the Pulsafeeder parts catalog.
Check valves are used to permit flow in the intended direction while restricting reverse flow under appropriate operating conditions.
Correct valve selection is important for maintaining the fluid-handling arrangement specified for the equipment.
PVC Construction
The manufacturer catalog includes PVC in the assembly description.
PVC is commonly used for compatible industrial chemical feed and water treatment components. Chemical compatibility must be confirmed for the actual process fluid, concentration and temperature.
HY and C Material Designations
The catalog also includes the designations HY and C.
These designations are commonly associated with Hypalon-type elastomer and ceramic components in Pulsafeeder parts nomenclature. However, the exact material assignments and included components for this specific assembly should be confirmed using the manufacturer parts breakdown.
Nominal 1/2-Inch Connection
The catalog identifies the 41638 with a nominal 1/2-inch size.
The precise connection configuration, including thread type or tubing interface, is not established by the abbreviated catalog description.
Potential Applications
- Compatible Pulsafeeder chemical metering pump assemblies
- Industrial chemical feed system maintenance
- Water treatment dosing equipment
- Replacement of manufacturer-specified back check valves
