Question 1

Do you supply desalination & high-purity water valves in Yokkaichi?

Accepted Answer

Yes. Vajra Industrial Solutions supplies Butterfly Valve (Duplex / Super Duplex), High-Pressure Ball Valve (SWRO Membrane Train), Check Valve (Pump Discharge, Duplex), Diaphragm Valve (Chemical Dosing & Permeate) for desalination & high-purity water applications in Yokkaichi, Mie Prefecture. Yokkaichi in Mie Prefecture is one of Japan's historic petrochemical kombinato (industrial complexes), integrating the Cosmo Oil refinery with Mitsubishi Chemical, Toa Oil, Kyowa, and downstream fine-chemical and polymer producers, and is also home to the giant Kioxia/Toshiba Yokkaichi semiconductor fab - one of the world's largest NAND flash plants; the mix of hydrocarbon, chemical, and ultra-high-purity semiconductor service spans an unusually wide valve range - API 6D and JIS/JPI ball, gate, and globe valves in A216 WCB and A351 CF8M for refinery and petrochemical lines, high-temperature WC9 and F22 valves for cracking and reforming, fire-safe and low-fugitive valves for VOC and emissions control, PTFE- and PFA-lined valves for corrosive fine-chemical duty, and electropolished SS 316L high-purity diaphragm, bellows, and ball valves for ultra-pure water, process gas, and chemical delivery in semiconductor manufacturing; JIS B2220 flanges, licensor and JIS specifications, and full traceability are required; Vajra Industrial Solutions supplies Yokkaichi refinery, petrochemical, and semiconductor buyers with API 6D, high-temperature, lined, and high-purity valve packages with JIS-compliant connections and full material certification. We offer export documentation and delivery to Yokkaichi in 7–14 business days with full documentation and third-party inspection.

Question 2

What certifications are required for desalination & high-purity water valves in Yokkaichi?

Accepted Answer

For desalination & high-purity water in Yokkaichi, the applicable standards are: ASME B16.34, ISO 9001:2015, AWWA C504 (Butterfly valves for water), AWWA C516 (Large diameter rubber-seated butterfly valves), NSF 61 / NSF 372 (Drinking water materials), EN 593 (Butterfly valves), NACE MR0175 (Sour service - for associated oil & gas desal). All valves are supplied with full documentation including material test reports (EN 10204 3.1/3.2), pressure test certificates, and dimensional inspection reports. Third-party inspection (TPI) by EIL, Bureau Veritas, Lloyd's Register, or the client's nominated inspector can be arranged.

Question 3

What is the delivery time for desalination & high-purity water valves to Yokkaichi?

Accepted Answer

Standard stock sizes: export documentation and delivery to Yokkaichi in 7–14 business days. Custom sizes and special materials (Duplex, Hastelloy, P91): 4–8 weeks manufacturing lead time. Express dispatch available for urgent site requirements. Contact us at +91-9979774557 or sales@vajravyuh.com with your specification and required delivery date.

Question 4

What valve materials are required for seawater reverse osmosis (SWRO) plants?

Accepted Answer

SWRO plants require careful material selection due to seawater's high chloride content (28,000–38,000 ppm Cl⁻ in typical seawater). For seawater-wetted components: Duplex stainless UNS S31803 (PREN ~35) is the standard minimum for body, disc, and trim; Super Duplex UNS S32750 (PREN ~42) is preferred for warm seawater (above 30°C) and brine concentrate. SS 316 (PREN ~25) is insufficient for long-term seawater service and will develop pitting corrosion. On the permeate side (pure water): SS 316L is suitable, or PVDF/CPVC thermoplastics for aggressive pure water service.

Question 5

What pressure class is required for SWRO membrane train valves?

Accepted Answer

SWRO (Seawater Reverse Osmosis) systems typically operate at 55–80 bar feed pressure (depending on seawater salinity and temperature). This corresponds to ASME Class 300 (approximately 51 bar at ambient temperature in SS 316) to Class 600 (approximately 103 bar). Most SWRO designers specify Class 600 rated valves (in SS 316 or Duplex) for membrane train isolation to provide an adequate safety margin above the 80 bar maximum operating pressure. High-pressure booster pump stages may require Class 900 in some ultra-high recovery designs.
