Description

Anmelder: Albrecht-Automatik GmbH., KÖLN 1, Burgmauer 4 Beschreibung; Kolbenventil mit Vollentlastung. Applicant: Albrecht-Automatik GmbH., KÖLN 1, Burgmauer 4 Description ; Piston valve with full relief.

Anwendungsgebiet;Field of use;

Speziell für Einsatzzwecke als Absperrorgan für neutrale Flüssigkeiten und Gase mit wechselnder Durchflußrichtung.Especially for use as a shut-off device for neutral liquids and gases with changing direction of flow.

Zweck; Im Gegensatz zu herkömmlichen Ventilen Purpose; In contrast to conventional valves

schließt dieses Kolbenventil nach beiden Durchflußrichtungen ab. Der Kolben im Ventil wird vom Durchflußmedium nicht, angehoben.closes this piston valve in both flow directions. The piston in the The valve is not lifted by the flow medium.

Besonders bei Gasbrenner-Anlagen wird die Forderung gestellt, daß die Absperrarmatur beidseitig absperren muß. Das Kolbenventil erfüllt diese Forderung durch die Vollentlastung. Particularly with gas burner systems, the requirement is that the shut-off valve must shut off on both sides. The piston valve fulfills this requirement with full relief.

Erzielbare Vorteile; Achievable benefits ;

Durch den vollentlasteten Ventilkolben sind nur geringe Stellkräfte für das Öffnen des Ventiles erforderlich. Werden die Ventile für Flüssigkeiten eingesetzt, erfolgt das öffnen wie auch Schließen ohne die bekannten"Flüssigkeitsschläge." Due to the fully relieved valve piston, only low actuating forces are required for the It is necessary to open the valve. Become the valves for liquids when used, the opening and closing takes place without the well-known "liquid hammer."
