Operating Principle

For VND□00/04□ (N.C. Type)

When air is exhausted from 12 (P1) port, valve 4 linked to piston 5 is closed via the action of the return spring 6.

  • For Opening the Valve
     When pressurized air enters through port 12 (P1), the pilot air that has entered under the piston moves upward, opening the valve.
  • For Closing the Valve
     When fluid is exhausted from port 12 (P1), the pilot air under the piston is exhausted and the valve closed via the action of the return spring.

For VND□02□ (N.O. Type)

In contrast for the N.C. type, when air is exhausted from port 10 (P2), the valve is held open via the return spring. Pressurized air through port 10 (P2) closes the valve.

Precautions

External Pilots

For the pilot port 12 (P1) and 10 (P2) piping, follow the information below for the relevant model.

  • Port 12 (P1): VND□O□D external pilot / VND□O2D bleed port
  • Port 10 (P2): VND□O□D bleed port / VND□O2D external pilot

SMC recommends installing a silencer on the bleed port to prevent debris from getting into the valve.

Piping

Use heat resistant parts for fittings, tubing, etc. (Compression fittings, fluorine resin tubes, copper piping, etc.)

Other Precautions

  • *See the SMC catalog for information other than that detailed above.
  • *Pictures are of representational models.

Adiabatic Space

There is a gap between the body and cover for heat insulation (*approx. 1 mm [see figure below]).
