Basis Weight

Basis weight control is critical to the operation of both Pulp and Paper machines. The basis weight control valve requires the ability to respond to small input changes of <1%. in the vast majority of applications this requirement is met with either 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. this results in production downtime trouble shooting basis weight valve issues.
Fisher’s V150 Vee-Ball® , 2052 Spring diaphragm actuator and DVC6200 digital valve controller provide the performance 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 the need for dedicated spare parts is eliminated. Production downtime is reduced as in-house knowledge/expertise to trouble shoot and repair is readily available.
Vee-Ball™ V150 is a flanged valve for throttling or on-off operation for many different applications in the process industries. The V150 is available in NPS 1 through 20, CL150 (DN 25 through 300, PN 10/16). Trim components are interchangeable between Design V150, V200 and V300.
