Designed for the 2-1/2" EHSC-Series Valve
EHSC-RKV250 is specifically identified for the 2-1/2" Dixon EHSC-Series Spring Check Valve when FKM elastomer replacement components are required.
Dixon offers separate repair-kit part numbers according to valve series, nominal size, and elastomer material. Selecting the correct kit requires confirming all three characteristics before ordering.
Although Dixon groups HSC and EHSC repair components within the same HSC/EHSC-Series repair-kit family, EHSC-RKV250 should be matched to the appropriate EHSC-Series valve rather than selected solely by its 2-1/2" size or FKM material.
FKM Elastomer Components
EHSC-RKV250 uses FKM for its replacement sealing components. FKM elastomers are used in many process applications where their particular chemical and temperature-resistance characteristics are appropriate.
Material suitability depends on the actual process media, concentration, temperature, cleaning chemicals, sanitation procedures, and operating conditions.
Always verify FKM compatibility with the complete process environment before replacing a different elastomer material or returning the valve to service.
FKM vs. EPDM Repair Kit
EHSC-RKV250 - FKM
- 2-1/2" EHSC-Series
- FKM body gasket
- FKM plunger O-ring
- Use where the corresponding FKM configuration is required
- Part number suffix RKV identifies the FKM repair-kit configuration
EHSC-RKE250 - EPDM
- 2-1/2" EHSC-Series
- EPDM elastomer configuration
- Corresponding EPDM repair-kit option
- Use where the valve and process require EPDM components
- Part number suffix RKE identifies the EPDM repair-kit configuration
HSC vs. EHSC Repair Kit Selection
EHSC-Series
- EHSC-RKV250 is the 2-1/2" FKM option
- EHSC-RKE250 is the 2-1/2" EPDM option
- Match the repair kit to an EHSC-Series valve
- Verify valve identification before ordering
HSC-Series
- HSC-RKV250 is the separate 2-1/2" FKM option
- HSC-RKE250 is the separate 2-1/2" EPDM option
- Uses HSC-specific repair-kit part numbers
- Do not select by nominal size alone
Spring Check Valve Maintenance
Spring check valves contain moving and sealing components that should be inspected as part of an appropriate preventive-maintenance program. Elastomer components can gradually wear, deform, harden, swell, or otherwise deteriorate depending on service conditions.
The EHSC-RKV250 allows the body gasket and plunger O-ring to be replaced without automatically replacing every internal valve component.
During valve service, inspect the remaining internal components and sealing surfaces for damage, wear, corrosion, contamination, product buildup, or other conditions that could affect valve operation.
If components beyond the supplied body gasket and plunger O-ring are damaged or worn, address those components separately rather than relying on the repair kit alone.
When to Consider Replacing the Seals
Condition-Based Maintenance
- Visible gasket deterioration
- Cut, cracked, or deformed O-ring
- Leakage around sealed interfaces
- Elastomer swelling or hardening
- Damage found during valve disassembly
Preventive Maintenance
- Scheduled valve inspection
- Routine sanitary-system maintenance
- Service after demanding process conditions
- Maintenance based on facility procedures
- Replacement following inspection of existing seals
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 appropriate 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 valve size, and elastomer material.
For a 2-1/2" EHSC-Series valve requiring FKM elastomers, EHSC-RKV250 is the corresponding repair-kit configuration.
For a 2-1/2" EHSC-Series valve requiring EPDM instead, select the corresponding EHSC-RKE250 repair kit.
A 2-1/2" HSC-Series valve uses a different HSC-prefixed repair-kit part number. Confirm the valve series from the existing equipment or documentation before ordering.
Installation & Maintenance
Before servicing the spring check valve, isolate the affected section of the piping 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. Remove the existing body gasket and plunger O-ring carefully to avoid damaging adjacent components or sealing surfaces.
Inspect the valve internals during disassembly. Check the plunger, spring, body surfaces, and other internal components for excessive wear, corrosion, contamination, product buildup, or physical damage.
Clean the appropriate sealing surfaces and install the replacement FKM components in their proper locations. Avoid cutting, twisting, pinching, overstretching, or otherwise damaging the new elastomers during installation.
Reassemble the valve according to Dixon procedures and confirm that internal components move correctly before returning the assembly to service.
After reassembly, test the valve under appropriate system conditions and inspect the assembly for leakage and proper check-valve operation.
Our team can help confirm your HSC or EHSC valve series, nominal size, elastomer material, and correct Dixon repair-kit part number before you order.

What valve does Dixon EHSC-RKV250 fit?
EHSC-RKV250 is the FKM repair-kit configuration for compatible 2-1/2" Dixon EHSC-Series Spring Check Valves.
What size is EHSC-RKV250?
Dixon identifies EHSC-RKV250 for the 2-1/2" EHSC-Series valve size.
What elastomer material does EHSC-RKV250 use?
EHSC-RKV250 uses FKM elastomer components.
What is included with EHSC-RKV250?
The 2-1/2" EHSC repair kit contains one body gasket and one plunger O-ring.
Does EHSC-RKV250 include a body gasket?
Yes. One replacement body gasket is included.
Does EHSC-RKV250 include a plunger O-ring?
Yes. One replacement plunger O-ring is included.
Does the kit include the spring or plunger?
No. The EHSC-RKV250 repair kit is identified as containing the body gasket and plunger O-ring. Do not assume additional internal valve components are included.
What is the EPDM equivalent of EHSC-RKV250?
Dixon lists EHSC-RKE250 as the corresponding 2-1/2" EHSC-Series repair kit using EPDM elastomer components.
What is the difference between EHSC-RKV250 and HSC-RKV250?
Both are 2-1/2" FKM repair-kit configurations within Dixon's HSC/EHSC product family, but EHSC-RKV250 is identified for the EHSC-Series while HSC-RKV250 is the separate HSC-Series part number.
Can I select the repair kit based only on valve size?
No. Confirm the valve series, nominal size, and required elastomer material. HSC and EHSC valves have separate repair-kit part numbers even when the nominal size and elastomer are the same.
When should the body gasket and O-ring be replaced?
Replacement may be appropriate when inspection identifies wear, deformation, cracking, chemical deterioration, leakage, or other damage, or when replacement is required by the facility's preventive-maintenance program.
Can I substitute EPDM for FKM?
Do not change elastomer materials without confirming compatibility with the valve configuration, process fluid, cleaning chemicals, operating temperature, and other system requirements.
Can the EHSC-Series valve be serviced in the field?
Dixon's HSC/EHSC documentation describes these valves as serviceable equipment and provides repair kits and maintenance procedures for replacing service components.
What should I verify before ordering EHSC-RKV250?
Confirm that the existing valve is a compatible 2-1/2" Dixon EHSC-Series Spring Check Valve and that FKM is the required elastomer material for the valve and process conditions.
