MECA-INOX – PS4 Ball valve

Stainless Steel Ball valve for general use


  • Installation quick and easy
  • Modular build
  • Built-in body seals to guarantee internal/external tightness
  • Seats profiles designed for upstream/downstream sealing
  • Seats elasticity to absorb pressure stress
  • Progressive bearing to optimize operating torques
  • Ruff to avoid the seat to be taken away when upstream pressure is higher than downstream pressure



Butt Weld, Orbital welding connection, Threaded, Tri-Clamp


316L (1.4404)




The PS4 has some distinctive features, such as the unique concept of Meca-Inox with revolving connection component, which makes installation quick and easy.


The PS4 is modular build with various control levers and actuators. No USP Class VI 121 ºC certificate.
