Introduction – PN16 Butterfly Valve Supplier India

Krishna Industries (KELOR), based in Ahmedabad, Gujarat, India, is a trusted B2B supplier of PN16 Butterfly Valves sourced from verified Indian manufacturers. We supply PN16 Butterfly Valves across all major material grades — Cast Iron (CI), Ductile Iron (DI), Carbon Steel (WCB), Stainless Steel SS304, and Stainless Steel SS316 — with EPDM, NBR, Viton, and PTFE seat options — sizes 50mm to 600mm — in wafer type and lug type configurations.

The PN16 Butterfly Valve is rated for 16 bar (232 PSI) nominal pressure — higher than the standard PN10 rating — making it the correct specification for pumping mains, industrial process piping, chemical plant lines, fire fighting pump discharge headers, and any Indian EPC project where operating pressure exceeds 10 bar or where the project specification explicitly calls for PN16.

We supply PN16 Butterfly Valves to EPC contractors, purchase managers, plant maintenance MRO teams, fire fighting contractors, chemical plant procurement departments, and bulk industrial buyers across Gujarat and PAN India. All supplies come with GST invoices, Material Test Certificates (MTC), and complete B2B documentation.

Also referred to as: PN16 BFV, 16 bar butterfly valve, PN16 wafer butterfly valve, PN16 lug butterfly valve, Class 125 butterfly valve — all referring to the same higher-pressure rated butterfly valve used in Indian industrial and infrastructure projects requiring pressure ratings above PN10.

PN16 vs PN10 — Which Butterfly Valve Does Your Project Need?

This is the most important question EPC engineers and purchase managers ask when specifying butterfly valves. Here is a clear guide:

Factor	PN10 Butterfly Valve	PN16 Butterfly Valve
Pressure Rating	10 Bar (145 PSI)	16 Bar (232 PSI)
Cost	More economical	Slightly higher — heavier body
Typical Use	Water supply, HVAC, irrigation, STP/ETP	Pumping mains, industrial process, fire fighting headers
Fire Fighting	Distribution piping	Pump discharge headers — PN16 recommended
Chemical Plant	Low-pressure utility	Process line isolation — PN16 standard
Pumping Mains	Not recommended above 10 bar	✅ Correct specification
Project Spec Says	PN10 or 10 bar	PN16, 16 bar, or Class 125
When Unsure	Use if pressure confirmed below 10 bar	✅ Safer choice for critical service

Rule of thumb for Indian EPC projects: Always match the valve pressure rating to your project’s design pressure — not operating pressure. If design pressure is 12 bar, specify PN16 not PN10. Krishna Industries can assist with correct specification — WhatsApp us your project details.

Frequently Asked Questions

1. What does PN16 mean in butterfly valve?

PN16 refers to the nominal pressure rating of 16 bar (232 PSI). This valve is designed and tested for fluid pressures up to 16 bar — higher than the standard PN10 — making it suitable for pumping mains, fire fighting headers, industrial process lines, and high-pressure EPC projects across India.

2. When should I use PN16 instead of PN10?

Use PN16 when your project design pressure exceeds 10 bar, when project specification explicitly states PN16, for fire fighting pump discharge headers (mandatory PN16 per Indian NBC and IS 15105), for pumping mains, and for industrial process isolation where higher pressure margin is required.

3. Is PN16 butterfly valve mandatory for fire fighting systems?

Yes — Indian fire fighting standards and NBC (National Building Code) typically mandate PN16 rating for pump discharge headers and main distribution piping. Always check your project fire fighting specification — PN16 is the safe standard choice for fire fighting pump headers.

4. What body material should I choose?

CI or DI for water mains and pumping stations. WCB for industrial process lines. SS304 for moderate chemical and corrosion-resistant service. SS316 for aggressive chemical, pharmaceutical, and coastal applications.

5. What seat material for water and pumping mains?

EPDM is the standard and most widely used seat material for water mains, pumping stations, HVAC, and fire fighting applications across India.

6. What is the difference between wafer type and lug type PN16?

Wafer type sandwiches between two flanges — economical, both sides always connected. Lug type bolts independently to each flange — allows one-side pipeline removal for maintenance. Choose lug type where maintenance access or one-side isolation is required.

7. What sizes are available?

50mm to 600mm (2 inch to 24 inch). Larger sizes available on request.

8. Can the valve be automated?

Yes — all valves are supplied with ISO 5211 actuator mounting pad. Pneumatic and electric actuator packages available from 50mm to 400mm.

9. Do you provide GST invoice and MTC?

Yes — every order includes GST invoice (GSTIN: 24AKLPP6499B1ZT) and Material Test Certificate. Hydrostatic test certificates available on request.

10. What is the MOQ?

MOQ is 10 Nos. Bulk project orders welcome with better pricing and confirmed delivery timelines.

11. Can I order PN16 and PN10 butterfly valves together in one order?

Yes — Krishna Industries supplies multiple valve types and pressure ratings in consolidated single orders with single GST invoice — reducing EPC procurement complexity and logistics cost.

12. Do you supply for export?

Yes — IEC registered exporter (IEC: AKLPP6499B). Export supply FOB Mundra or JNPT to UAE, Saudi Arabia, Vietnam, and other markets.
