Butterfly Valve Manufacturer in Ahmedabad — Flowjet Valve
Flowjet Valve is a butterfly valve manufacturer based in GIDC Kathwada, Ahmedabad. We supply industrial butterfly valves to chemical plants, water treatment facilities, pharmaceutical manufacturers, power projects, and HVAC systems across Gujarat and India.
Our valves are manufactured in-house — not assembled from outsourced components. Every valve goes through hydrostatic testing and seat-leak testing before dispatch. Material test certificates come standard with every order.
If you need a butterfly valve that’s correctly specified, properly tested, and supported after delivery — you’re in the right place.
Materials We Work With
Getting the material selection right is more important than most buyers realise. A butterfly valve that works perfectly on a water line may fail quickly in chemical service if the seat or body material isn’t matched to the fluid.
Here’s what we supply and when each material suits:
Body materials:
- Cast iron — General water and utility service, moderate pressure
- Ductile iron — Higher mechanical loads, improved impact resistance over cast iron
- Stainless steel SS 304 — Food, pharma, mildly corrosive environments
- Stainless steel SS 316 — Aggressive chemical service, chloride-bearing fluids, offshore environments
Seat and liner materials:
- EPDM — Water, steam, dilute acids and alkalis. Not suitable for hydrocarbons
- NBR (Nitrile) — Oil, fuel, and hydrocarbon service
- PTFE — Broad chemical resistance including acids, alkalis, and solvents
- Viton (FKM) — High temperature chemical service up to 200°C
- Natural rubber — Municipal water, wastewater, abrasive slurry applications
If you’re unsure which combination suits your process condition — send us the fluid name, concentration, and operating temperature. Our technical team will confirm the right specification before we quote.
Actuation Options
More plants in Gujarat are moving toward automated valve operation. We supply butterfly valves in manual and actuated configurations — as pre-assembled, tested packages.
Manual operation:
- Lever handle — for valves up to DN 200 in light service
- Gear operator — for larger sizes or higher torque requirements
Pneumatic actuated:
- Single-acting (spring return) — fail-open or fail-closed as specified
- Double-acting — for high-cycle applications
- Supplied with solenoid valve and limit switch as required
Electric actuated:
- On/off or modulating control
- Available in 24V DC, 230V AC, and 415V AC configurations
- Suitable for remote operation and BMS integration
All actuated assemblies are assembled and function-tested at our facility before dispatch. We don’t send the valve and actuator separately for field assembly.
Why Plant Engineers Choose Flowjet Valve
In-house manufacturing. We machine, assemble, and test at our GIDC Kathwada facility. We don’t outsource critical manufacturing processes to job shops.
Documented quality. Every valve ships with a material test certificate, hydrostatic test record, and seat-leak test report. These aren’t available on request after delivery — they’re produced as standard.
Right material for your application. We don’t default to the cheapest standard configuration. Our team reviews the application before confirming a product. Wrong material specifications get caught at the enquiry stage — not after the valve is installed.
Ahmedabad-based supply. For Gujarat-based plants, this means faster delivery, accessible spare parts, and a technical team you can actually visit when you need to.
Spare parts availability. Replacement seats, discs, and stem seals for our standard range are available from stock. A maintenance requirement doesn’t mean a long procurement cycle.
Testing and Quality
Every butterfly valve we supply goes through a defined quality process before it leaves our facility.
Hydrostatic shell test — Confirms body integrity under pressure. Conducted at 1.5 times the rated working pressure.
Seat leak test — Confirms shutoff performance. Conducted at 1.1 times the rated working pressure to API 598 / IS standards.
Dimensional inspection — Face-to-face dimensions, flange drilling, and bore concentricity checked against relevant standards.
Material verification — Body, disc, and seat materials verified against purchase specifications. Material test certificates retained for every production batch.
For projects requiring third-party inspection, radiographic testing of castings, or PMI (positive material identification), these can be arranged at the time of order.
Standards and Certifications
Our butterfly valves are manufactured and tested in conformance with applicable Indian and international standards.
- IS 13095 — Indian standard for butterfly valves
- API 609 — Butterfly valves for general service
- API 598 — Valve inspection and testing
- ASME B16.5 / IS 1538 — Flange dimensions and drilling
- EN 558 — Face-to-face dimensions (for European-standard pipelines)

Frequently Asked Questions
What is a butterfly valve and how does it work?
A butterfly valve controls flow by rotating a disc on a central stem. A quarter turn — 90 degrees — moves the valve from fully open to fully closed. The disc sits in the centre of the pipe and rotates to allow or block flow. Because the disc remains in the flow path even when open, butterfly valves produce slightly higher pressure drop than full-bore designs like ball valves. This is acceptable in most general service applications.
What is the difference between wafer type and lug type butterfly valves?
A wafer type butterfly valve sits between pipeline flanges and relies on through-bolts to hold it in place. It cannot hold pressure if the downstream piping is removed. A lug type butterfly valve has threaded inserts that allow independent bolting to each pipeline flange — so it can hold pressure with the downstream side disconnected. Lug type is required for dead-end service.
Which seat material should I choose for my butterfly valve?
The seat material depends on your process fluid. EPDM suits water and mild chemical service. NBR suits oils and hydrocarbons. PTFE suits aggressive chemicals including acids and solvents. Viton suits high-temperature chemical service. If you’re unsure, send us your fluid name, concentration, and operating temperature and we’ll confirm the correct material.
What sizes of butterfly valves does Flowjet Valve manufacture?
We manufacture butterfly valves from DN 50 to DN 1200. Standard sizes in common configurations are available from stock. Larger sizes and non-standard configurations are manufactured to order.
Can I get actuated butterfly valves from Flowjet Valve?
Yes. We supply pneumatic and electric actuated butterfly valves as pre-assembled, tested packages. Actuated assemblies are tested for function before dispatch — not sent separately for field assembly.
Does Flowjet Valve supply butterfly valves for chemical plant service?
Yes. We supply butterfly valves for chemical plants in EPDM, PTFE, NBR, and Viton seat configurations with cast iron, ductile iron, and stainless steel body options. We confirm material compatibility for the specific chemical service before confirming supply.
