Express dispatch available for urgent site requirements. Contact us at +91-9979774557 or sales@vajravyuh.com with your specification and required delivery date.
What butterfly valve standard applies to water treatment in India?
For water treatment in India, butterfly valves are specified per IS 13095 (Indian Standard for butterfly valves for water supply and sewerage), EN 593 (European standard), or AWWA C504. IS 13095 is the most common for domestic municipal projects. The valve body is typically ductile iron (GGG-50 per ISO 1083 or IS 1865) with EPDM seat. For export-oriented projects or international standards (World Bank, JICA-funded), EN 593 or AWWA C504 is specified.
What valves are used in RO desalination plants?
RO desalination plants use several valve types: High-pressure butterfly valves or ball valves (in SS 316 or Duplex) for RO membrane train isolation; energy recovery devices (ERD) require high-cycle valves with precise control; brine reject lines use SS 316 due to high chloride concentration; pre-treatment (clarification, filtration) uses ductile iron butterfly valves. All valves in contact with potable water must comply with NSF 61 or equivalent.
