Critical Valve Requirements

Abrasion resistance for pulp fibres — natural rubber or EPDM liners with hardness 60–70 Shore A for knife gate seats
Full-bore, self-draining design for pulp stock — prevents fibre plug formation when valve is closed
Chemical resistance to bleaching agents: ClO₂, H₂O₂, NaOH, SO₂ — PTFE or PVDF diaphragms for oxidising bleach chemicals
High-temperature capability for black liquor (up to 150°C) — SS 316 or alloy steel body; A217 WC6 for recovery boiler steam
IBR certification for valves on recovery boiler steam lines (high-pressure steam service)
Replaceable wear components (sleeves, liners, diaphragms) — essential for minimising mill downtime
Bi-directional sealing for knife gate valves on pulp stock lines where reverse differential is possible

Madrid is Spain's industrial and EPC contracting hub — Repsol (Spain's largest oil company), Técnicas Reunidas (global EPC contractor), Indra, and Sacyr all headquartered here drive consistent demand for API 6D ball valves, gate valves, globe valves, butterfly valves, check valves, and actuated valve packages for Spanish and international project procurement; Madrid's water authority (Canal de Isabel II) manages one of Europe's largest urban water systems, creating sustained demand for large-diameter butterfly valves, gate valves, and strainers. We offer export documentation and delivery to Madrid in 7–14 business days with full documentation and third-party inspection.
What certifications are required for pulp & paper industry valves in Madrid?
For pulp & paper industry in Madrid, the applicable standards are: ISO 9001:2015, ASME B16.34, TAPPI TIS 0304-08 (Pulp consistency), IBR (Steam service in recovery boiler), PED 2014/68/EU (European pressure equipment). 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.
What is the delivery time for pulp & paper industry valves to Madrid?

Express dispatch available for urgent site requirements. Contact us at +91-9979774557 or sales@vajravyuh.com with your specification and required delivery date.
What valve is best for pulp stock (fibrous suspension) service?
For pulp stock (cellulosic fibre suspension at 3–14% consistency), knife gate valves are the most common choice. The blade-gate design allows the blade to cut through the fibre mat and seat against a rubber seat liner, providing reliable on/off isolation. Full-bore design prevents fibre plug formation in the valve body. Pinch valves are also widely used for lower-pressure stock lines (PN 6/10) and offer excellent resistance to fibre abrasion (no internal metal in the flow path). Globe and ball valves are not suitable for medium-to-high consistency stock without special design modifications.
What materials resist black liquor in kraft pulp mill valves?
Black liquor is a challenging fluid: strongly alkaline (pH 12–14), high dissolved solids (50–70% dry solids in strong black liquor), contains sodium carbonate, sodium sulphate, sodium sulphide, and lignin, at temperatures of 90–150°C. Carbon steel is susceptible to corrosion in hot black liquor. SS 316 (A351 CF8M) is the standard material for black liquor valve bodies and trim. For high-temperature, high-solids strong black liquor near the evaporators and recovery boiler: Duplex stainless (F51) or Alloy 20 provides better corrosion resistance. White liquor (NaOH + Na₂S, pH 13–14): SS 316L minimum; Duplex preferred.
