⚠️ Read before comparing prices: Many suppliers listing “SS304 wafer check valve” at ₹300–₹950 are supplying a Cast Iron body with SS304 disc only — the body and internals are not stainless. KELOR supplies full SS304 body + SS304 disc + NBR seat — 100% stainless steel wetted parts throughout. These are completely different products at different price points. Compare correctly before ordering.

Why Full SS304 Body Costs More Than “SS304 Wafer Valve” at ₹300–₹950

The price confusion in the market is significant and important to understand before specifying:

✅ Full SS304 Body + SS304 Disc (This Product — KELOR)

Body: SS304 (AISI 304 / ASTM A351 CF8) — full stainless steel body casting
Disc: SS304 stainless steel disc
Spring, shaft, internals: SS316 / SS304
All wetted parts: 100% stainless steel — no ferrous contact with media
Standard: API 6D — full design and test standard conformance
Price (DN100): ₹4,380
Specify for: Food GMP, pharma, chemical, potable water (avoiding iron leach), offshore, SS piping systems where all components must be SS — wherever media contact with iron is not acceptable

⚠️ CI Body + SS304 Disc (Commonly Mislabelled “SS304 Valve”)

Body: Cast Iron (FG 200) — iron body
Disc: SS304 stainless steel disc only
Internals: SS shaft, rubber seat
Wetted parts: Iron body contacts media — ferrous leach possible
Standard: May be BS 5155 or similar — not full API 6D
Price (DN100): ₹950–₹1,200 (widely available)
Specify for: HVAC, general water, fire fighting where the CI body is acceptable — DO NOT specify for food GMP, pharma, all-SS piping systems, or wherever iron body corrosion is a concern

ℹ️ The rule: If your piping system is all-stainless (SS304 or SS316 pipe, fittings, valves throughout), you must specify a full SS304 body wafer check valve — not CI body with SS disc. CI body in an all-SS system creates a galvanic dissimilar metal pair that accelerates corrosion on both the CI valve and the adjacent SS pipe. For food GMP and pharmaceutical systems, CI body valves are typically non-compliant with 3-A Sanitary and FDA design requirements regardless of disc material.

Applications — Why SS304 Body (Not CI Body) Is Required

🍽️ Food & Dairy GMP

Full SS304 body is mandatory for FDA 21 CFR, 3-A Sanitary, and FSSC 22000 compliance in food and dairy processing piping — CI body valves are non-compliant.

💊 Pharmaceutical & Biotech

SS304 or SS316 body required for USP Purified Water, WFI, and pharmaceutical process systems where iron contact with product water is not permissible.

⚗️ Chemical Processing

SS304 body for dilute acid, alkali, and chemical process lines where CI body would corrode — SS304 body + PTFE seat for aggressive chemical service.

⚓ Marine & Offshore

Full SS304 or SS316 body essential for marine vessel freshwater systems, offshore platform utility piping, and all seawater splash zone applications.

💧 Potable Water (High Spec)

SS304 body prevents iron leach into drinking water — specified by consulting engineers for hospitals, hotels, and institutional building potable water systems requiring zero metallic taste.

⛽ Oil & Gas

SS304 body + NBR seat (as per listed prices) for oil and gas utility service, gas distribution, LPG lines, and fuel handling where API 6D compliance is required.

🏗️ EPC Projects

Bulk supply for projects specifying “CF8 wafer check valve API 6D” — the CF8 casting designation is the foundry grade equivalent of SS304. Full MTC and API 598 test certs available.

🌡️ High Temperature

SS304 body + PTFE seat for steam service and high-temperature lines above 120°C where the CI body becomes inadequate and rubber seats fail — up to 180°C.

Frequently Asked Questions — SS304 Wafer Check Valves

Why is the SS304 wafer check valve price so much higher than valves listed at ₹300–₹950?

The ₹300–₹950 products listed on directories are typically Cast Iron body valves with SS304 disc only — not full SS304 body. KELOR’s SS304 wafer check valve starts at ₹1,160 for DN25 because the entire body is cast in SS304 (ASTM A351 CF8 stainless steel casting) — not cast iron. This makes every wetted surface fully stainless, meeting API 6D design standard, and suitable for food GMP, pharmaceutical, chemical, and marine applications where a CI body would fail or be non-compliant. If your application requires all-SS wetted parts — full SS304 body is the correct product. If you only need SS disc protection with a CI body in clean water service, the CI body with SS disc (available from our CI wafer check valve page) is the correct and more economical choice.

What is CF8 and is it the same as SS304?

CF8 is the ASTM A351 foundry grade designation for cast SS304. When SS304 is melted and cast into a valve body or disc, it becomes CF8 — the chemistry is equivalent to wrought SS304 (AISI 304) but designated differently because the casting process produces a slightly different microstructure than wrought plate or bar. CF8 (cast SS304) and AISI 304 (wrought SS304) are chemically equivalent: both contain approximately 18–20% chromium and 8–11% nickel. When a drawing or specification says “CF8 wafer check valve,” it means SS304 body. CF8M is the cast equivalent of SS316. On KELOR’s SS304 wafer check valves, the body is CF8 (cast SS304) and the disc is CF8 — both confirmed by MTC on request.

Which seat material should I specify — NBR or EPDM for SS304 check valves?

Specify NBR (Nitrile) — the standard seat in KELOR’s listed prices — for oil, gas, petroleum, diesel, compressed air with oil carry-over, and fuel service. NBR is the standard for API 6D check valves in the oil and gas industry. Specify EPDM instead for water service, HVAC, potable water, pharmaceutical water, and any service involving biocide-treated cooling water — EPDM is superior to NBR in water service. Specify PTFE for chemical service, concentrated acids/alkalis, pharmaceutical GMP (FDA 21 CFR), high-purity water, and steam. If ordering for water or pharma service, tell us at time of inquiry so we can specify EPDM or PTFE instead of the standard NBR — this does not affect the body or disc material or price significantly.

Can you supply SS316 body wafer check valves?

Yes — SS316 body (ASTM A351 CF8M) + SS316 disc + seat material wafer check valves are available on request. SS316 body adds approximately 25–40% to the SS304 body pricing and has a 3–4 week lead time as it is not standard stock. Specify SS316 body for marine seawater service, offshore platform utility piping, coastal chemical plant, and any application where SS304 may pit due to chloride levels above 150 ppm. For most chemical service, food GMP, pharmaceutical, and inland potable water, SS304 body is adequate and significantly more economical. WhatsApp size, quantity, and seat material for SS316 body pricing.

What documentation is available — MTC, API 6D certificate, hydro test?

For standard orders: GST invoice + E-Way bill. For project/EPC orders on request: (1) Material Test Certificate (MTC) per heat number confirming CF8 / SS304 composition (Cr, Ni, C, Si, Mn content) and mechanical properties; (2) Hydrostatic test certificate per API 598 confirming body test at 225 PSIG and seat test at 165 PSIG; (3) Dimensional inspection report confirming face-to-face per API 594; (4) Certificate of conformance per API 6D. For export orders: Certificate of Origin (COO), commercial invoice, packing list, and material test certificate. Third-party inspection (TPI) by BVQI, CEIL, or TUV can be arranged for large project orders on request at additional cost. Advise documentation requirements at time of inquiry.
