All butterfly valve types shown below are available for immediate dispatch from our Ahmedabad stock. As a trusted butterfly valve supplier in India, we maintain rigorous quality control on every batch.
A butterfly valve is a quarter-turn rotary valve in which a disc rotates 90° around a central shaft to open or close flow. The disc remains in the flow path at all times, making butterfly valves significantly more compact and lighter than gate or globe valves at equivalent bore sizes. This is the preferred choice for large-diameter industrial pipelines across India where space, weight, and cost per bore size are critical.

Expert Selection Guide: Avoid Costly Specification Errors
⚠️ Most common Indian project error: Specifying NBR seat for biocide-treated HVAC cooling water. Chlorine and bromine-based biocides degrade NBR within 6–12 months. Always specify EPDM for HVAC cooling water butterfly valves.
Seat Material Selection — EPDM vs NBR vs PTFE vs Viton
| Seat Material | Temp Range | ✨ Specify For | ❌ Not For |
|---|---|---|---|
| EPDM | −40°C to +120°C | HVAC chilled/condenser water, potable water, treated water, biocide-treated cooling tower water, DM water. Standard for Indian HVAC/Water BFV specs. | Mineral oil, petroleum, diesel, hydrocarbons (EPDM swells). |
| NBR (Nitrile) | −20°C to +80°C | Raw water (non-treated), sewage, irrigation canal water, non-treated cooling water without biocide. | Biocide-treated HVAC water, hot water above 80°C, ozone-treated water. |
| PTFE | −10°C to +180°C | Aggressive chemicals, concentrated acid/alkali, high temperature (>120°C), seawater, pharmaceutical processes. | Standard water where EPDM is adequate (PTFE has higher operating torque). |
| Viton (FKM) | −15°C to +200°C | Hydrocarbon service, fuel oil, diesel, crude oil, high-temperature chemical, petroleum refinery. | Hot water and steam (Viton is over-specified and unnecessary for water). |
Disc Material Selection — CI vs SS304 vs SS316
| Disc Material | Cost | ✨ Specify For | ❌ Not For |
|---|---|---|---|
| CI Disc | Lowest | Raw water, sewage, slurry, irrigation — non-potable, infrequent operation where minor corrosion is acceptable. | Potable water, treated HVAC water (CI corrodes, contaminates water, fails in 3–5 years). |
| SS304 Disc (CF8) | Standard | Most common. HVAC treated water, potable water, DM water, mild chemical. 15–20+ year disc life. Standard for Indian BOMs. | High chloride (>150 ppm), seawater (SS304 pits in aggressive chloride service). |
| SS316 Disc (CF8M) | Premium (+15–20%) | Coastal industrial (Mundra, Hazira, Dahej, Vizag, Chennai), seawater cooling, high chloride. Mo addition resists pitting. | Standard inland non-chloride HVAC and water supply (unnecessary premium). |
Wafer Type vs Lug Type — Which to Specify?
| Feature | Wafer Type | Lug Type |
|---|---|---|
| Body Design | Plain body — clamped between two pipeline flanges using through-bolts. | Threaded inserts (lugs) cast into body — each flange bolts independently. |
| Dead-end Service | ❌ Both flanges must always be present. | ✨ Downstream flange can be removed while valve stays bolted upstream. |
| Cost | ✨ Lower — simpler body casting. | Higher — threaded lug inserts add manufacturing cost. |
| Specify When | ✨ Standard in-line service (correct choice for ~90% of Indian installations). | Pump discharge, pipeline terminal end, equipment isolation requiring downstream removal. |
💡 PTFE Seat Note: Operating torque is 20–40% higher than EPDM at the same size and pressure. If specifying a PTFE seat, specify a gear operator one size earlier than the EPDM threshold (i.e., from DN125 or DN150 rather than DN200).

Frequently Asked Questions — Butterfly Valve Specification
What is the difference between wafer type and lug type butterfly valves?
A wafer type butterfly valve has a plain body clamped between two pipeline flanges using through-bolts spanning both flanges. Both flanges must always be present, and the valve cannot be used as a dead-end valve. A lug type butterfly valve has threaded inserts (lugs) cast into the valve body, allowing each pipeline flange to bolt independently. The downstream piping can be unbolted and removed for maintenance while the valve remains securely bolted to the upstream flange. Specify lug type for pump discharge isolation, terminal ends of pipelines, and equipment isolation. Specify wafer type for all standard in-line service — it is more economical and the correct choice for approximately 90% of Indian butterfly valve installations.
Why is an EPDM seat specified for HVAC cooling water butterfly valves instead of NBR?
Indian HVAC cooling water systems use biocide treatment chemicals — typically chlorine or bromine-based — to prevent Legionella growth in cooling towers. NBR (nitrile rubber) degrades in these biocide chemicals within 6–12 months, causing the seat to harden, crack, and fail. EPDM resists chlorine and bromine-based biocides reliably throughout its service life. EPDM also handles the full HVAC temperature range from chilled water at 7°C to hot water circuits at 80°C. For all Indian HVAC butterfly valve specifications involving biocide-treated cooling water, an EPDM seat is the mandatory specification.
From what size should I specify gear operated instead of lever for a butterfly valve?
The standard Indian project specification threshold is DN150 (6″) for gear operated valves. From DN50 to DN125 (2″–5″), lever operated is standard, as the torque is comfortable for single-person manual operation. At DN150, a lever becomes heavy for frequent operation — specify a gear operator if the valve will be operated regularly. From DN200 (8″) and above, gear operated is mandatory, as lever torque exceeds comfortable single-person operation. For PTFE seat valves, operating torque is approximately 20–40% higher than EPDM at the same size — specify a gear operator one size earlier than the EPDM threshold.
What is the difference between a CI disc and an SS304 disc in a CI butterfly valve?
Both use the same Cast Iron body and EPDM/NBR seat — only the disc material differs. A CI disc corrodes in treated HVAC water and potable water. Within 3–5 years, the corroded disc leaves rust particles that contaminate treated water and lose structural integrity, causing valve failure. An SS304 disc is corrosion-resistant, offering a 15–20+ year service life in treated water with no contamination risk. For HVAC and water treatment butterfly valve BOMs, an SS304 disc is the standard specification. A CI disc is acceptable only for raw water, sewage, and irrigation where water quality is low and contamination is not a concern.
Does a butterfly valve fit ANSI, DIN, and IS flanges without modification?
Yes. The standard wafer butterfly valve body (ISO 5752 Series 20 face-to-face) has a universal body design that fits between ANSI B16.5 Class 150, DIN PN10, DIN PN16, and IS 1538 flanges of the same nominal bore without any modification. The through-bolt pattern depends on the connecting flanges, not the valve body. No change to the valve is needed when the flange standard changes. This universal fit is one of the main reasons wafer butterfly valves dominate Indian industrial piping.
Do you supply butterfly valves conforming to IS 13095 for government tenders?
Yes. Butterfly valves sourced from our Ahmedabad facility conform to IS 13095 and API 609. IS 13095 test reports and API 598 hydrostatic test certificates are available for government tender documentation, including JICA, World Bank, and state water board-funded bulk water supply projects. WhatsApp your project specification and BOM — we confirm the applicable certificate before quotation.
What is the approximate price of a butterfly valve in India?
Butterfly valve prices in India depend on size, body material, disc material, seat material, operator type, and end connection. Approximate ex-works Ahmedabad pricing for a CI body, SS304 disc, EPDM seat, wafer type valve: DN50 (2″) ₹450–850, DN100 (4″) ₹900–1,800, DN150 (6″) ₹1,800–3,500, DN200 (8″) ₹3,200–6,500, DN300 (12″) ₹8,500–16,000, DN600 (24″) ₹55,000–95,000. SS316 disc adds 10–15%, PTFE seat adds 15–20%, lug type adds 10–15%, and DI body adds 20–25%. Electric actuators add ₹8,000–₹45,000. These are indicative prices — for a firm quotation, WhatsApp your exact BOM with quantity.
What is the delivery time for butterfly valves from Ahmedabad?
Ready stock sizes (CI wafer and lug DN50 to DN300 with EPDM seat) dispatch within 2 to 3 working days from Ahmedabad. SS304, SS316, and larger sizes (DN350 to DN600) dispatch in 7 to 10 working days. Electric and pneumatic actuated valves take 10 to 15 working days, depending on actuator brand and specification. Pan India supply via road transport: Gujarat and Maharashtra (2–3 days), South India (4–6 days), North India (3–5 days), East India (4–7 days). E-Way bills are provided for all interstate supply, along with a GST invoice and API 598 test certificate.
Can butterfly valves be used for fire fighting applications?
Yes. Butterfly valves are widely specified in Indian fire fighting systems for pump discharge isolation, hydrant ring main sectionalization, and sprinkler zone isolation. The standard fire fighting specification is a CI body, EPDM seat, PN16, lever or gear operated, wafer or lug type valve. These must conform to IS 13095 and API 609. Note: for fire fighting non-return valve requirements (preventing backflow), you need a fire fighting check valve — see our dedicated fire fighting check valve page for CI wafer check valve specifications.
