Chem-Tech Back Check Valve Assembly

The 41795 back check valve is a replacement component used in the applicable Chem-Tech chemical metering pump fluid-handling arrangement.

Back check valves are designed to support controlled one-directional fluid movement and help limit reverse flow when installed in the correct system configuration.

Actual valve operation and performance depend on the manufacturer design, installation position and operating conditions.

PVC Construction

The manufacturer catalog identifies the valve assembly with a PVC material designation.

PVC is commonly used in chemical feed systems because of its suitability for many water treatment and industrial fluid-handling applications.

Material compatibility must be confirmed for the specific chemical, concentration, temperature and pressure.

Hypalon Material Designation

The catalog uses HY, commonly identified as Hypalon, within the valve configuration description.

Hypalon is associated with chlorosulfonated polyethylene elastomer materials used in selected industrial sealing applications.

The exact internal component using the Hypalon material should be confirmed using the manufacturer assembly drawing.

1/2-Inch NPT Connections

The Pulsafeeder 41795 is listed with a 1/2 x 1/2-inch NPT connection configuration.

Correct connection size and thread compatibility are important when installing the valve in a chemical feed system.

Confirm the mating fittings, thread arrangement and installation requirements before purchasing.

Potential Applications

• Chem-Tech chemical metering pump maintenance
• Industrial chemical dosing systems
• Water treatment chemical feed equipment
• Replacement of worn back check valves
• Chemical injection line maintenance
• Original equipment valve assembly replacement
• Compatible fluid-handling system servicing

Inspection and Maintenance

Inspect the existing valve for leakage, damaged threads, material deterioration, deposits and signs of restricted flow.

Check the associated piping and fittings for damage or incorrect installation.

Replace defective valve assemblies using the manufacturer-specified component.

Installation Guidelines

Before installing Pulsafeeder 41795, confirm the correct valve configuration and connection requirements.

Disconnect power where applicable, isolate the chemical feed system and release pressure before servicing.

Install the valve in the manufacturer-specified orientation using compatible fittings and approved installation practices.

After installation, inspect all connections for leakage and verify proper system operation.

Ordering Information

Order using the exact manufacturer part number 41795.

Verify the PVC/Hypalon configuration, 1/2-inch NPT connections and compatibility with the intended Chem-Tech pump or chemical feed system.
