AVDA
AVDA is self-acting differential pressure relief controller used for constant flow control or bypass control. Controller opens on rising differential pressure. The controller has a control valve, an actuator with one control diaphragm and handle for differential pressure setting. For apartment block heating, district heating plant and central heating systems.
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.
