Wafer Butterfly Valve Supplier in India — Complete Range

Krishna Industries (KELOR), based in Ahmedabad, Gujarat, supplies the complete Wafer Butterfly Valve range — CI, DI, WCB, SS304, SS316, and lined body options — all disc types, all seat types, all operators, all installation types. Furthermore, all wafer BFV types are available with GST invoice, API 598 test certificate, and Pan India dispatch from Ahmedabad. MOQ is 10 Nos per line item.

A wafer butterfly valve is clamped between two pipeline flanges using through-bolts — no flanges on the valve body itself. Consequently, it is the most compact and economical butterfly valve end connection — lighter and shorter face-to-face than lug or double-flanged types — and the standard specification for the majority of Indian industrial, civil, and HVAC butterfly valve applications.

Frequently Asked Questions

1. What is the difference between wafer type and lug type butterfly valve?

A wafer type butterfly valve is clamped between two pipeline flanges — both upstream and downstream flanges must remain in place when the valve is in service. It is the most compact and economical butterfly valve end connection. A lug type butterfly valve has threaded lugs bolted independently to each pipeline flange — the downstream piping can be removed while the valve stays in place. Specify wafer for standard in-line service where both flanges will always be present. Specify lug for dead-end service — pump discharge, pipeline termination — where downstream pipework may need to be removed for maintenance.

2. Can a wafer butterfly valve be used for throttling?

A wafer butterfly valve can perform moderate throttling but is not designed for precision flow control. At intermediate positions the disc creates a non-linear flow characteristic — small disc movements near the closed position create large pressure drops while movements near the open position have little effect on flow. For precise flow control, specify a globe valve or a modulating control valve. For on/off isolation with occasional coarse flow adjustment, a butterfly valve in the 30°–70° open range is acceptable in most water and HVAC applications.

3. Which seat material is correct for HVAC chilled water?

Specify EPDM seat for HVAC chilled water, condenser water, and hot water. EPDM resists the temperature range of HVAC systems (-40°C to +120°C), is compatible with biocide and scale inhibitor treatment chemicals standard in Indian HVAC cooling water systems, and handles ozone-treated water. Do not specify NBR for HVAC — NBR degrades in biocide-treated cooling water. Do not over-specify PTFE for standard HVAC water — PTFE has higher operating torque and cost without benefit in non-aggressive water service.

4. What is the MOQ?

MOQ is 10 Nos per line item. Mixed BOM orders across multiple body materials, disc types, seat types, and sizes are welcome. WhatsApp your complete BOM for consolidated project pricing within 2 hours.
