Description
Dixon EHSC-RKV100 Spring Check Valve Repair Kit - 1" FKM
Dixon EHSC-RKV100 is an FKM elastomer repair kit designed for compatible 1" Dixon EHSC-Series Spring Check Valves.
This genuine Dixon service kit provides the primary replacement sealing components used during maintenance of the 1" EHSC valve. Unlike the larger 1-1/2" through 4" EHSC repair kits, the 1" configuration uses two body gaskets along with a single plunger O-ring.

Important 1" EHSC Kit Difference
The 1" EHSC-Series repair-kit configuration differs from the larger EHSC valve sizes.
EHSC-RKV100 contains two body gaskets and one plunger O-ring. By comparison, Dixon specifies one body gasket and one plunger O-ring for the 1-1/2" through 4" EHSC repair kits.
This makes it important to select the repair kit by exact valve series and nominal size rather than assuming all EHSC kits contain the same quantity of components.
Designed for the 1" EHSC-Series Valve
EHSC-RKV100 is specifically identified for the 1" Dixon EHSC-Series Spring Check Valve when FKM replacement elastomers are required.
Dixon offers separate repair kits according to valve series, nominal size, and elastomer material. Matching all three characteristics helps ensure the replacement components correspond to the existing valve.
Although HSC and EHSC kits are grouped within the same repair-kit family, they use separate part numbers and should not be selected by nominal size alone.
FKM Elastomer Components
EHSC-RKV100 uses FKM for the supplied replacement sealing components. FKM elastomers are commonly used in process applications where their chemical and temperature resistance characteristics are appropriate.
Actual suitability depends on the process media, concentration, temperature, cleaning chemicals, sanitation procedures, and other service conditions.
Verify FKM compatibility with the complete process environment before installation, especially if the existing valve uses a different elastomer material.
FKM vs. EPDM Repair Kit
EHSC-RKV100 - FKM
- 1" EHSC-Series
- Two FKM body gaskets
- One FKM plunger O-ring
- Use where the corresponding FKM configuration is required
- RKV suffix identifies the FKM repair-kit configuration
EHSC-RKE100 - EPDM
- 1" EHSC-Series
- EPDM elastomer configuration
- Corresponding EPDM repair-kit option
- Use where the valve and process require EPDM components
- RKE suffix identifies the EPDM repair-kit configuration
HSC vs. EHSC Repair Kit Selection
EHSC-Series
- EHSC-RKV100 is the 1" FKM option
- EHSC-RKE100 is the 1" EPDM option
- 1" EHSC kits use two body gaskets
- Match the repair kit to an EHSC-Series valve
HSC-Series
- HSC-RKV100 is the separate 1" FKM option
- HSC-RKE100 is the separate 1" EPDM option
- Uses HSC-specific repair-kit part numbers
- Do not substitute based on size alone
Spring Check Valve Maintenance
Dixon HSC/EHSC spring check valves are serviceable 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-RKV100 provides the two body gaskets and plunger O-ring required for the 1" FKM 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.
When to Consider Replacing the Seals
Condition-Based Maintenance
- Visible gasket deterioration
- Cut or cracked O-ring
- Seal deformation
- Leakage around valve interfaces
- Swelling, hardening, or chemical damage
Preventive Maintenance
- Scheduled valve inspection
- Routine sanitary-system maintenance
- Service after demanding operating conditions
- Facility preventive-maintenance procedures
- Replacement following inspection of existing elastomers
Typical Applications
Food & Beverage Processing
- Food processing equipment
- Beverage process systems
- Dairy applications
- Breweries and wineries
- Compatible sanitary process piping
Sanitary Process Systems
- Pharmaceutical applications
- Hygienic process piping
- Compatible fluid-transfer systems
- Systems using EHSC-Series spring check valves
- Applications requiring compatible FKM elastomers
Repair Kit Selection
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 1" EHSC-Series valve requiring FKM elastomers, EHSC-RKV100 is the corresponding repair-kit configuration.
For a 1" EHSC-Series valve requiring EPDM instead, select EHSC-RKE100.
A 1" HSC-Series valve uses separate HSC-prefixed repair-kit part numbers, so verify the valve series from the equipment or Dixon documentation before ordering.
Installation & Maintenance
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 both existing body gaskets and the 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 two replacement FKM body gaskets and one FKM plunger O-ring in their correct positions. Avoid cutting, twisting, pinching, overstretching, or otherwise damaging the new elastomers.
Reassemble the valve according to Dixon procedures and confirm that 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.

What valve does Dixon EHSC-RKV100 fit?
EHSC-RKV100 is the FKM repair-kit configuration for compatible 1" Dixon EHSC-Series Spring Check Valves.
What size is EHSC-RKV100?
Dixon identifies EHSC-RKV100 for the 1" EHSC-Series valve size.
What elastomer does EHSC-RKV100 use?
EHSC-RKV100 uses FKM elastomer components.
What is included with EHSC-RKV100?
The kit includes two body gaskets and one plunger O-ring.
Why does the 1" EHSC kit contain two body gaskets?
Dixon specifies two body gaskets for the 1" EHSC valve configuration. The larger 1-1/2" through 4" EHSC kits use a different component arrangement with one body gasket and one plunger O-ring.
Does EHSC-RKV100 include a plunger O-ring?
Yes. One plunger O-ring is included.
Does the kit include the spring or plunger?
No. Dixon identifies EHSC-RKV100 as containing two body gaskets and one plunger O-ring. The spring, plunger, and valve body are not identified as included.
What is the EPDM equivalent of EHSC-RKV100?
Dixon lists EHSC-RKE100 as the corresponding 1" EHSC-Series EPDM repair kit.
What is the difference between EHSC-RKV100 and HSC-RKV100?
Both are 1" FKM repair-kit part numbers, but EHSC-RKV100 is for the EHSC-Series while HSC-RKV100 is for the HSC-Series. Confirm the valve series before ordering.
Can I choose the repair kit based only on valve size?
No. Confirm the valve series, nominal size, and elastomer material. Dixon uses separate part numbers for different series and materials.
Can I substitute EPDM for FKM?
Do not change elastomer materials without confirming compatibility with the valve, process fluid, cleaning chemicals, operating temperature, and system requirements.
When should these seals be replaced?
Replacement may be appropriate when inspection identifies wear, cracking, deformation, chemical deterioration, leakage, or other damage, or when required by a preventive-maintenance schedule.
What should I verify before ordering EHSC-RKV100?
Confirm that the existing valve is a compatible 1" Dixon EHSC-Series Spring Check Valve and that FKM is the required elastomer material.
