Régulateurs de pression de sécurité
Product types shown: 4
AVDA
L’AVDA est un régulateur de pression différentielle auto-moteur utilisé pour assurer un débit mini dans des installations à débitvariable. Le régulateur s’ouvre lorsque la pression différentielle augmente..
Il comporte une vanne de régulation, un actionneur avec un diaphragme d’équilibrage et une poignée pour le réglage de la pression différentielle.
Pour chauffage d’immeubles résidentiels, installation de chauffage urbain et systèmes de chauffage central.
SAF
The controller is a self acting, medium-operated proportional controller which prevents exceeding pressure before the valve by automatic opening.The actuator features 2 diaphragms which enable the valve to open in case of a defect at the control diaphragm. This controller is mainly used in district heating systems.Design-tested according to DIN 4747 (SÜV) and the AGFW guidelines.
SAVA
SAVA is a self-acting safety pressure relief controller primarily for use in district heating systems.
The controller is normally closed and opens on rising pressure. It is used for pressure relief control and as a protection against excess pressure in front of the valve.
The controller has a control valve, an actuator with two control diaphragms and a spring(s) for pressure setting.
Design-tested according to DIN 4747-1 and AGFW - FW 506.
SAVD
SAVD is a self-acting safety pressure reduction controller primarily for use in district heating systems. The controller is normally opened and closes on rising pressure. It is used for pressure reduction control and as a protection against excess pressure behind the valve.
The controller has a control valve, an actuator with two control diaphragms and a spring(s) for pressure setting.
Design-tested according to DIN EN 4747-1 and AGFW guidelines FW 504.
