Linear

PLA/PLAS

Double acting and spring return pneumatic linear valve actuators for on-off and regulating service.

Features & Benefits:

  • Electroless nickel plated and polished cylinder provides maximum corrosion resistance and reduces friction
  • Hard chromium plated and polished stainless steel piston rod guarantees corrosion protection and minimal friction
  • Floating type piston seals provide low hysteresis and high sensitivity, preventing sticking problems
  • Piston rod support bushing in bronze with sintered PTFE provides minimal friction and extended service life
  • Mechanical travel stop for stroke adjustment
  • Fabricated carbon steel adapter spool with accessories provision enables adaptation to any type of valve
  • PLAS totally enclosed spring cartridge ensures personnel safety and simplifies assembly
  • PLAS spring action can be changed easily in the field from to close to open or vice versa
  • Special coatings for offshore or corrosive environments
