Frequently Asked Questions

Common questions about valve selection, specifications, and certifications for this industry.

Which industrial valves are used in pulp and paper mills?

Butterfly valves, ball valves, gate valves, control valves, check valves and knife gate valves may be used in pulp and paper mills. Selection depends on the process medium, fibre content, consistency, pressure, temperature and whether the application requires isolation or flow control.

Which valve is suitable for pulp slurry and fibre-handling applications?

Knife gate valves are commonly considered for certain pulp slurry applications because their gate design can help handle media containing fibres and suspended solids. The final selection depends on pulp consistency, solids content, pressure, valve design and the required sealing performance.

How do I select a valve for abrasive pulp, stock preparation and paper mill processes?

Evaluate the pulp consistency, fibre characteristics, abrasive content, operating pressure, temperature, flow rate and frequency of operation. Seat design, internal clearances, wear resistance and maintenance requirements should also be considered when selecting a suitable valve.

Which valves are suitable for chemical dosing and bleaching processes in paper mills?

The valve must be compatible with the specific chemical, its concentration, operating temperature and pressure. Suitable ball, diaphragm, lined or other chemical-service valves may be considered after verifying the compatibility of the body, trim, seat and lining materials.

Which valves are used for water, steam and condensate systems in paper mills?

Butterfly, gate, globe and check valves may be considered depending on the service. Selection should account for operating pressure, temperature, flow requirements, condensate conditions and the applicable pressure-temperature ratings of the valve.

How can I reduce valve maintenance and downtime in pulp and paper plants?

Select valves according to the actual process conditions and specify suitable materials, sealing arrangements and wear-resistant designs where required. Correct sizing, appropriate installation, preventive maintenance and monitoring of leakage or operating problems can also help reduce unplanned downtime.

How do I choose between a knife gate valve and a butterfly valve for pulp applications?

A knife gate valve may be considered for suitable slurry and fibre-handling duties, while a butterfly valve may be preferred for compact isolation in compatible pipeline services. The choice depends on pulp consistency, solids content, pressure, flow conditions, sealing requirements and the manufacturer's application guidance.
