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

What certifications are required for pulp & paper industry valves in Bontang?
For pulp & paper industry in Bontang, 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).

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 Bontang?
Standard stock sizes: export documentation and delivery to Bontang 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.
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.
