valsteam actuators - pa45

PA45

Pneumatic multi-spring linear actuators PA series for modulating and open-close duty, ideal for demanding industrial valve control tasks.

MATERIAL

Mild steel

SIZES

700 cm2

MAX. AIR SUPPLY

Up to 6,5 bar

RATED STROKE

valsteam actuators - el

EL

Electric linear actuators EL series for modulating and open-close duty of control and process technology to operate control valves. The self-locking stem/stem nut is driven by an electric motor via a gearing. Load and limit switches define the stops for the end positions.

POSITIONING FORCES

1,2 to 25 kN

RATED STROKE

Up to 100 mm

SUPPLY VOLTAGES

24 V, 115 V, 230 V, 400 V AC 50/60Hz
24 V DC

IP RATING

IP 43 / IP 65

valsteam actuators - elr

ELR

Electric linear actuators ELR series for modulating and open-close duty of control and process technology to operate control valves. The self-locking stem/stem nut is driven by an electric motor via a gearing. Load and limit switches define the stops for the end positions. In case of power failure, the electric linear actuator runs spring-driven into the respective fail-safe position (thrust rod either extended or retracted). In modulating duty, the end position seating is made via limit switches.

POSITIONING FORCES

≥ 0,9 to ≥ 2,2 kN (closed)
≤ 4,0 to ≤ 5,3 kN (open)

RATED STROKE

Up to 46 mm

SUPPLY VOLTAGES

24 V, 115 V, 230 V, 400 V AC 50/60Hz
24 V DC

IP RATING

IP 54

valsteam actuators - avf234s-avm234s

AVM234S-AVF234S

The AVM234S / AVF234S valve actuators offer automatic adaptation to the stroke of the valve, precision activation and high energy efficiency with minimal operating noise. Ideal for use with any DSH series direct steam injection humidifier and in TDS (Total Dissolved Solids) control systems VCP blowdown valves. In case of power failure/interruption, the AVF234S actuator runs, spring-driven, into its respective fail-safe position (thrust rod extended). In modulating duty, the end position seating is made via limit switches.

POSITIONING FORCES

2 or 2,5 kN

RATED STROKE

Up to 49 mm

SUPPLY VOLTAGES

24 V, 115 V, 230 V AC 50/60Hz
24 V DC

IP RATING

IP 66
