BIS ISI Mark Certification for Butterfly Valves – IS 13095:2020
Ensure Industrial Reliability and Legal Compliance with Standphill India
Butterfly valves are widely used in water supply, wastewater, HVAC, chemical, and oil industries. These valves control flow through quarter-turn rotation and are critical for system efficiency and safety. To ensure quality and performance, the Government of India has made BIS ISI certification mandatory for butterfly valves under IS 13095:2020.
If you're a manufacturer or importer of butterfly valves, obtaining a BIS license is a legal requirement, and Standphill India is here to guide you every step of the way.
What Is IS 13095:2020?
IS 13095:2020 is the Indian Standard that specifies requirements for metallic butterfly valves for general purposes. It includes:
Design and construction standards
Face-to-face and flange dimensions
Materials of construction
Pressure ratings (PN10, PN16, etc.)
Performance testing (hydrostatic, leakage, operational)
This standard ensures butterfly valves meet the required levels of mechanical strength, sealing efficiency, and dimensional accuracy, making them fit for industrial use.
Why BIS Certification for Butterfly Valves Is Mandatory
Under the Quality Control Order (QCO) notified by the Department for Promotion of Industry and Internal Trade (DPIIT):
Butterfly valves must be certified under IS 13095:2020 before they can be sold or imported in India.
Only ISI-marked valves are legally permitted.
Non-compliance results in penalties under the BIS Act, 2016.
BIS Certification Process for Butterfly Valves

Manufacturers must apply through the Manakonline portal with:
Product specifications

3. Factory Audit
BIS officials audit the manufacturing facility to assess:
Production capability

Consistency and traceability
4. ISI Mark License Issuance
