Pressure Relief Controllers
Products shown: 7
AFA-VFG2(1)
The controller is a self-acting pressure relief controller primarily for use in district heating systems. The controller is normally closed and opens on rising pressure. The controller has a control valve, an actuator with one control diaphragm and a spring(s) for pressure setting. Further on two valve versions are available: – VFG 2 with metallic sealing cone – VFG 21 with soft sealing cone
AFPA 2/VFG 22(1)
The controller is a self-acting differential pressure relief controller primarily for use in district heating systems. The controller is normally closed and opens on rising differential pressure. Ordering Example 1: Differential pressure controller, return mounting, DN 65, kVS 60 m3 /h, PN 16, metallic sealing, setting range 1-3 bar, Tmax 150 °C, flange – 1× VFG 22 DN 65 valve Code no: 065B5500 – 1× AFPA 2 actuator Code no: 003G5691 – 2× Impulse tube set AF Code no: 003G1391 Products will be delivered separately. The controller has a control valve, an actuator with one control diaphragm and a spring(s) for pressure setting. Further on two valve versions are available: ∙ VFG 22 with metallic sealing cone ∙ VFG 221 with soft sealing cone Together with Danfoss intelligent electrical actuator AMEi 6 intelligent optimization functions are available: ∙ iNET-intelligent network balancing
