Power-tork PTFE Coated Aluminium Coaxial Valve

PTFE Coated Coaxial Valve


  • We have six sizes of Power-tork Coaxial Valves, going from DN 15 (1/2″) to DN 50 (2″).
  • There are two different versions: double acting/air open air close (DA) and single acting air open/fail close (SR).
  • Power-tork Coaxial Valves are equipped with an on-off operator and are suitable for group 2 type fluids (not dangerous).
  • Inside the coaxial valves there is a pneumatic mechanism, which can be supplied with instrument air via a 1/8” GAS/NPT interface or through a Namur solenoid valve.
  • Whilst not totally replacing actuated ball valves coaxial valves are a useful in many other applications.
