Valtek® Mark 100 and 100SC Linear Globe/Angle Control Valves

The Valtek Mark 100 and 100SC linear globe/angle control valves are purpose-built for severe-service trim and demanding process control. High Cv capacity, long stroke and precise spring-cylinder actuation support compact sizing and fine control, while clamped-in seating simplifies maintenance in challenging liquid and gas applications.

  • Cost-effective performance, as higher Cv capacity allows for smaller valve sizes
  • Superior process control made possible by long stroke lengths; the position accuracy, repeatability and assured response from the positioner; and the stiff and high-thrust, spring-cylinder actuator
  • Reduced downtime with the clamped-in seat and self-aligning seat ring
  • Severe service application versatility provided by a wide variety of noise abatement and anti-cavitation trims
