ACTAIR NG

Technical data

Enclosure: IP68

At a control pressure of 6 bar

Output torque [Nm]: ≤ 8000

T [°C]: ≥ -50 - ≤ +150

Description

Double-acting pneumatic actuator for mounting on quarter-turn valves (butterfly valves or ball valves). Actuator flange to ISO 5211. Control pressure up to 8 bar. Mounts on valves with square or flat shaft end. Force transmission via scotch-yoke kinematics provides output torques of up to 8000 Nm which are ideal for actuating

quarter-turn valves. Equipped with a visual position indicator and, depending on the actuator size, adjustable travel stops for open/closed position or closed position as standard. Optional separate or integrated manual override. Suitable for mounting control unit type series AMTROBOX, AMTRONIC, SMARTRONIC or any other device with an interface to VDI/VDE 3845.

Applications

Water engineering, energy engineering and industry

DYNACTAIR NG

Technical data

Enclosure: IP68

At a control pressure of 6 bar

Output torque [Nm]: ≤ 4000

T [°C]: ≥ -50 - ≤ +150

Description

Single-acting pneumatic actuator for mounting on quarter-turn valves (butterfly valves or ball valves). Actuator flange to ISO 5211. Control pressure up to 8 bar. Mounts on valves with square or flat shaft end. Force transmission via scotch-yoke kinematics provides output torques of up to 4000 Nm which are ideal for actuating

quarter-turn valves. Reset to fail-safe position in case of control air failure is effected by means of spring assemblies. Equipped with a visual position indicator and, depending on the actuator size, adjustable travel stops for closed position or open/closed position as standard. Optional separate or integrated manual override. Suitable for mounting control unit type series AMTROBOX, AMTRONIC, SMARTRONIC or any other device with an interface to VDI/VDE 3845.

Applications

Water engineering, energy engineering and industry

SISTO-LAD

Technical data

Control air pressure [bar]: ≤ 6

Closing force [N]: ≤ 20000

Description

Diaphragm actuator in compact design for mounting on valves with a linear stem movement (globe valves, diaphragm valves and gatevalves). Available in single-acting spring-to-close or spring-to-open design, or double-acting air-to-open/air-to-close design; suitable for mounting limit switches or positioners to suit customer

requirements, factory-mounted. Settings are adjusted during factory test run.

Applications

Building services, industry, power stations; suitable for abrasive and aggressive products such as service water, waste water, acids, alkaline solutions, sludges and suspensions.

SISTO-LAP

Technical data

Control air pressure [bar]: 5,5 - 10

Closing force [N]: ≤ 250000

Description

Piston actuator in heavy-duty design for mounting on valves with a linear stem movement (globe valves, diaphragm valves and gate valves). Actuator flange to DIN/ISO 5210. Available in single-acting spring-to-close or spring-to-open design, or double-acting air-toopen/air-to-close design; suitable for mounting limit switches or positioners to suit customer requirements, factory-mounted. Settings are adjusted during factory test run.

Applications

Building services, industry, power stations, food and beverage industries, and chemical industry. The pneumatic actuators can be used in potentially explosive atmospheres.
