Valworx 5818 Series Installation Instructions Manual

Models: 581856, 581857, 581876, 581877
READ THESE INSTRUCTIONS CAREFULLY BEFORE INSTALLING OR CONNECTING
POWER TO THE ACTUATOR. THE ACTUATOR MUST BE INSTALLED, COMMIS-
SIONED, OPERATED AND REPAIRED BY QUALIFIED PERSONNEL. COMPLY WITH
ALL APPLICABLE CODES, STANDARDS AND SAFETY REGULATIONS.
This document provides installation, operation and maintenance instructions for
Valworx 5818 series electric actuators with EPS Postitioner. These actuators are
typically used to operate quarter-turn valves. Every actuator has been fully tested
prior to shipment to ensure trouble free operation.

CONDITIONS FOR USE

Failure to follow any of these conditions and warnings may void the warranty.
Valworx expressly disclaims any and all damages including consequential damages
resulting therefrom.
1. If the entry point, connecting pipe or contained cable exceeds 60°C the user
shall select the appropriately rated cable, cable gland and/or conductors in the
conduit and shall install per the IOM.
2. The minimum yield strength and minimum tensile strength of the explosion proof
conduit connector are 450MPa and 700MPa respectively.
3. The rated load is 50Nm (58185X series) and 200Nm (58187X series). Do not
exceed the rated load.
4. The lens plate shall not be loosened or removed at any time.
5. This unit contains the adhesives TSE3854DS-W and WCC-87 and cannot be used
in an atmosphere containing the following saturated vapors: Acetic Acid (glacial),
Acetone, Ammonium Hydroxide (20% by weight), ASTM reference fuel C,
Diethyl Ether, Ethyl Acetate, Ethylene Dichloride, Furfural, n-Hexane, Methyl Ethyl
Ketone, Methanol, 2-Nitropropane, and Toluene.
6. This explosion proof actuator is rated for T5. Ambient temperatures shall not
exceed -25°C ~ +55°C (-13°F ~ 131°F).
1. To prevent the ignition of flammable gases, do not remove the cover while cir-
cuits are energized.
-avertissement– pour éviter l'inflammation des gaz inflammables, de vapeurs our
de poussiére, ne pas retirer le couvercle pendant que le circuit est sous tension
2. Explosion-proof sealing material shall be used to seal the explosion proof connect-
ing pipe, and the distance from the seal to the actuator shall not exceed 500mm.
-avertissement– un scellement doit étre installé a moins de 500 mm du boítier
3. The lens plate shall not be loosened or removed at any time.
4. The cable entry and connecting conduit shall not exceed 66°C(150.8°F) &
77°C(170.6°F) respectively.
5. Do not damage or otherwise make the nameplate illegible.
6. Avoid damaging or scratching the flameproof joints when servicing or installing
the actuator. Ensure the fastening screws connecting electric elements, junction
box cover, and motor box cover are appropriately tightened.
7. The electric motor cavity of this product is an independent explosion proof cavity.
Do not remove the motor cover or faying surface of the outlet lead.
8. This product must be grounded internally and externally. Ensure ground connec-
tions are secure and check regularly.
9. Wiring connections shall comply with applicable codes and standards. Connecting
cables shall have an explosion proof rating of at least Exdb IIC T5 Gb.
