Basis Weight

Basis weight control is critical to the operation of pulp and paper machines.

The basis weight control valve must be able to respond to small input changes of <1%. In the vast majority of applications, this requirement is met with either a pulsed input gear motor or a stepper motor actuator. The problem is maintenance of these specialized actuators; high-cost, dedicated spares are required. Typically there is a lack of in-house expertise to service these actuators, resulting in production downtime and the need to troubleshoot basis weight valve issues.

Choose a trusted solution.

The Emerson Fisher™ Vee-Ball™, Fisher™ 2052 Diaphragm Rotary Actuator, and Fisher™ FIELDVUE™ DVC6200 Digital Valve Controller have the performance capability required for basis weight control with proven results. The solution utilizes standard Fisher products used on many applications in a pulp mill, resulting in reduced maintenance costs and an eliminated need for dedicated spare parts. Production downtime is reduced as in-house knowledge/expertise to troubleshoot and repair is readily available.
