Plast-O-Matic Series PS Pilot Operated Solenoid Valves

The Series PS valve is pilot-operated and normally closed by design. It requires line pressure and flow for operating assistance. Under the correct pressure conditions the coil, when energized (power on), creates an electromagnetic field in the top section of the core tube. This force pulls the core and pilot seat upward, opening the pilot valve. The liquid pressure above the diaphragm is then vented through the open orifice of the pilot valve to the downstream piping. At this moment, the inlet pressure under the diaphragm lifts the diaphragm and opens the main valve orifice, thereby permitting full flow through the valve. When the coil is de-energized (power off), the pilot solenoid spring (not in the wetted area) pushes the core and pilot seat downward, closing the pilot valve. This causes pressure above the diaphragm to rise to inlet pressure level, forcing the diaphragm downward against the main valve seat sealing the valve. Can be used with all types of solutions including acids, caustics, solvents and chlorine solutions. Comes with the standard voltage 120/60 but other options available upon request.

  • CPVC (Corzan™) body
  • Viton™ or EPDM seals
  • PTFE Bellows barrier-type dynamic seal prevents leaking of fugitive emissions to the atmosphere
  • In-line design with bubble-tight shut-off
  • Direct acting with a simple push-pull plunger design
  • Normally closed
  • Minimum 5 psi differential required
  • Inlet rating 140 psi, back pressure rating to 70 psi
  • Molded coil & standard DIN connector; designed to meet NEMA 4X
  • Patented Fail-Dry® safety design feature provides advance visual warning if seal malfunctions
