EHSC-RKE200 is specifically identified for the 2" Dixon EHSC-Series Spring Check Valve when EPDM replacement elastomers are required.

Dixon offers separate repair-kit part numbers according to valve series, nominal size, and elastomer material. Confirm all three characteristics before selecting a replacement kit.

Although Dixon groups HSC and EHSC kits within the same repair-kit family, EHSC-RKE200 should be matched to the appropriate EHSC-Series valve rather than selected by nominal size alone.

EHSC-RKE200 uses EPDM for both supplied replacement sealing components. EPDM is commonly used in sanitary and process applications involving compatible water-based fluids, cleaning solutions, and temperature conditions.

Actual suitability depends on the process media, concentration, operating temperature, cleaning chemicals, sanitation procedures, and other service conditions.

Verify EPDM compatibility with the complete process environment before installation, particularly when replacing a valve that currently uses a different elastomer material.

Dixon HSC/EHSC spring check valves are serviceable valve assemblies with replaceable elastomer components. Routine inspection can help identify worn gaskets and O-rings before they contribute to leakage or improper valve operation.

EHSC-RKE200 provides the body gasket and plunger O-ring required for the 2" EPDM valve configuration.

During service, inspect the remaining valve components and sealing surfaces for wear, corrosion, contamination, product buildup, or physical damage.

If components beyond the supplied seals require replacement, obtain the appropriate Dixon service components rather than assuming they are included in this kit.

Before ordering, confirm the complete identification of the existing spring check valve. Repair-kit selection should account for the valve series, nominal size, and elastomer material.

For a 2" EHSC-Series valve requiring EPDM elastomers, EHSC-RKE200 is the corresponding repair-kit configuration.

For a 2" EHSC-Series valve requiring FKM instead, select the corresponding EHSC-RKV200 repair kit.

A 2" HSC-Series valve uses separate HSC-prefixed repair-kit part numbers, so confirm the valve series from the equipment or Dixon documentation before ordering.

Before servicing the spring check valve, isolate the affected section of the process system and completely relieve all internal pressure. Drain, clean, and decontaminate the valve according to the process media and facility procedures.

Disassemble the valve according to applicable Dixon instructions. Carefully remove the existing body gasket and plunger O-ring without damaging adjacent components or sealing surfaces.

Inspect the valve internals during disassembly. Check the plunger, spring, body surfaces, and other components for excessive wear, corrosion, contamination, product buildup, or physical damage.

Clean the appropriate sealing surfaces and install the replacement EPDM components in their proper locations. Avoid cutting, twisting, pinching, overstretching, or otherwise damaging the new elastomers.

Reassemble the valve according to Dixon procedures and confirm that the internal components move correctly before returning the valve to service.

After reassembly, test the valve under appropriate system conditions and inspect for leakage and proper check-valve operation.
