Nm); voltage input range from 24V to 230 V AC/DC; plastic, painted aluminium, gal-vanized steel or AISI 316 actuator case; on/off, on/off spring return, modulating actuator with or wi-thout integrated micro...

Shut-off - Gas Shut-off Damper SagiCofim Type of installation * Actuator protrusion only. For total protrusion, please consider also piate protrusion. Electric actuators are fixed to le-vers protection carter by an uni-versal piate (galvanized steel or AISI 316). This plate is designed to fix differ-ent type of actuators only switch-ing its own orientation or using different fixing holes. Different type of installation: • BFL type through fixing holes 3, with a 180° plate rotation respect to plate position as shown in the example; • LF / BFN type through fixing holes 4, with a 180° plate...

Shut-off - Gas Shut-off Damper SDL - SDLT Damper controls Type P Pneumatic actuator SDL - SDLT Shut-off dampers and Gas Shut-off dampers can be equipped with rotating pneumatic actuators (6 - 10 bar) and additional accessories such as solenoid valves and limit switches (mechanical, magnetic or inductive type). Actuator can be made of PTFE coated aluminium, painted steel, stainless steel or composite. Fail CLOSE A typical pneumatic system is composed by: • a rotating piston with a specific even number of springs (according to the model); • a 3 - ways solenoid valve; • a manometer and a...
