ARCA Regler GmbH 7 Functional description
Series 814 17 / 2811.2022 / 1.1
7 Functional description
The series 814 has been developed as a single-action, pneumatic piston
actuator for linear valves. The centrally located stem (2) is connected
through a coupling for this purpose to the operating stem of the valve.
The actuator stem (2) is precisely guided by a plain bearing (32) and the
air-pressurised pressure chamber is sealed by a special sealing element
with a wiper (33). A piston (21) is connected to the actuator stem (2), it
divides the actuator housing (11, 12, 13) into pressure and spring cham-
bers. The actuator stem (2) moves when the force applied by the actu-
ation signal air pressure is higher on one side of the piston (21) than the
force of the spring(s) (4, 5).

8 Installation ARCA Regler GmbH
18 / 28 Series 81411.2022 / 1.1
8 Installation
Place of installation The actuator should be easily accessible from at least one side and from
above.
Include a catwalk or similar in the planning in case of greater heights.
An electric crane or block and tackle should be provided.
Installation The actuator lantern (1) has a central bore and a hole circle that enables
rotation of the actuator in 45 degree steps. Attachment to the valve is by
means of hex bolts (47). Actuator and valve are coupled to each other
via a coupling.
The maximum permissible actuating forces of the valve must be ob-
served.
Installation position Please note:
CAUTION
Installation position
► Pipeline must be horizontal
► Actuator above the valve.
► Align the actuator and attached parts to the valve
Please consult us in case of a different installation position!

9.1 Adjustment
Stroke adjustment ▪CAUTION!Shear forces must not be transmitted to the actuator
stem (2) when coupling actuator and valve.
▪CAUTION!Do not turn the actuator stem (2) in a radial direction.
▪NOTICE!Adjust the stroke so that the closing position of the valve is
not hindered by the internal, non-adjustable stroke limitation of the
actuator.
9.2 Actuating signal connection
The actuator has air connections (Z...) with an internal thread.

9.3 Positioner installation
Mounting with ARCA mounting
bracket The actuator lantern (1) enables auxiliary devices to be attached on two
sides with the M8 fastening thread (modified mount conforming to
NAMUR / IEC 60534-6-1). Refer to the operating manual for the respect-
ive device for the mounting instructions.

10 Maintenance ARCA Regler GmbH
20 / 28 Series 81411.2022 / 1.1
10 Maintenance
10.1 Care
▪ Clean the stem (2) if necessary
– Clean the stem (2) of adhering dirt using a soft cloth
NOTICE!Never use sandpaper, since this will damage the sur-
face of the stem and reduce the lifetime of the stem sealing.
10.2 Maintenance
The actuator requires almost no maintenance.
Nevertheless, the connections and the piston seal must be checked reg-
ularly for leaks.
Depending on the operating conditions of the actuator, the operator is
responsible for defining appropriate inspection and maintenance inter-
vals.
