The pulp and paper industry ranks among the most demanding industrial sectors, operating under a broad range of extreme conditions. Papermaking is a complex, highly automated process that transforms raw materials into finished products through a series of mechanically and chemically intensive stages. Despite the advanced machinery and computerized controls used to monitor and optimize production, the operating environment remains exceptionally harsh.
From high-temperature boiler operations to dust-filled grinding and corrosive bleaching, every stage places unique stresses on equipment. Pneumatic systems and directional control valves are especially critical—continuous, precise operation ensures efficiency, safety, and minimal downtime.
VERSA's valves are engineered to perform where other solutions fail. Built for reliability and real-world durability, VERSA supports every critical stage of pulp and paper processing.
1. Boiler Plant: Remote and Explosion-Proof Applications
Challenges:
Mills often operate remote boiler or cogeneration plants that supply critical steam and power. These facilities are frequently located in remote and/or classified hazardous locations due to the presence of flammable gases and fuels, often under high pressure. Components must not only be explosion-proof but also withstand extreme ambient heat and long cable runs.

2. Mechanical Grinding: Combatting Dust and Vibration
Challenges:
The debarking and grinding areas are some of the harshest environments in the mill, with constant exposure to airborne wood dust, sap, dirt, grease, and heavy vibration. Valves installed near actuators are especially at risk of particulate intrusion, seal wear, and fatigue from continuous shock and motion. Without rugged construction and proper protection, valves can clog or fail prematurely, leading to costly downtime and increased maintenance cycles.

3. The Wet End: Corrosion Resistance is Key
Challenges:
At the wet end, pulp combines with water, sizing agents, and chemicals before forming sheets. Humidity and chemical exposure create a high risk of corrosion, making material compatibility and ease of maintenance critical.

4. Drying Section: Managing Fine Dust and Heat
Challenges:
As pulp transitions into paper, it moves through heated dryers and presses where elevated temperatures and fine airborne paper dust create severe operating conditions. Dust infiltration can lead to valve clogging, jamming, or premature failure, while prolonged heat exposure accelerates seal and gasket degradation, causing leaks or loss of control. To maintain reliability in this stage, valves must be engineered to withstand thermal stress, resist dust intrusion, and deliver consistent performance over high cycle rates.
