3 Integrated Functions into 1 Product

A multi-purpose fitting: - Piloted non-return valve - Flow regulator - Manual exhaust 1-piece fitting: integrated fittings for pilot port and supply port Mounted in pairs directly on the cylinder

Safer Pneumatic Installations

Designed to protect your installations: Blocks cylinder movement in a vertical or horizontal position Allows the cylinder to stop in a mid-stroke position Maintains loads in case of pressure loss or emergency shut-off* New machinery directive 2006/42/EC: our piloted non-return valve conforms to this directive to guarantee safe use and security of equipment.

* With a pneumatic stop, very slight movement of the cylinder is still possible. Only a mechanical stop will ensure a full and immediate stop.

The control valve alternately supplies the two cylinder chambers; the pilot connection is connected to the opposite supply chamber with a tee fitting. Exhaust flow is controlled by the flow regulator .

In case of an emergency stop or pressure drop, pilot pressure drops, closing the piloted non-return valves and blocking the cylinder rod.

The cylinder can be put into low position using a vent that empties the pressure chamber through the flow regulator and the control valve.

Close the control regulator before venting in order to avoid sudden release of the cylinder rod. Do not use in corrosive environments.
