Valbia Aluminium Pneumatic Actuator

Description

Manufactured in Italy by Valbia, these pneumatic actuators have a hard annodised aluminium body with blue coated end caps.

The rotation angle is between 0° and 90° with external stroke adjustments to regulate the opening and the closing +/-5°.  These actuators are perfect for mounting on ball, butterfly or plug valves.

Available in double acting 9 to 3101 Nm (6 bar pilot pressure) and single acting (spring return) 6.2 to 1652 (6 bar pilot air with full spring sets).

Maximum pilot pressure is 8 bar, with a working temperature range of -20°C to +85°C.

Generally available 2 to 3 working days for sizes DA32 to DA270 and SR52 to SR330
