Troubleshooting Guide
Multi-Voltage On/Off Electric Actuators
5610/5616 Series
Valve Misapplication
Sometimes electric actuated valves may fail due to misapplication or using the valve in the wrong application. Reviewing
and complying with the product specifications will ensure long-term trouble free operation. Specifications can be found
online or in the product data sheet. Customers that continue to have problems with an actuator will usually indicate one
of two things. Either the actuated valve is unsuitable for the application or it’s not in compliance with one or more of the
following issues:
Voltage:
The voltage must be within the operating range of the actuator.
Over voltage or under voltage may cause premature failure.
Temperature:
Operating outside the temperature rating will shorten the
life and ultimately cause the actuator to fail. Valworx 5610/5616 series
actuators must operate within the range of -4 to +158°F (-20 to +70°C).
Environment:
The 5610/5616 series actuators have an IP67 weather-
proof rating. Generally suitable for indoor or outdoor applications. Provides
a degree of protection against rain, splashing water and hose directed water
(Do not pressure wash). Protecting the actuator against rain, snow, ice and
UV (sunlight) will typically extend the life of the product. Highly corrosive
environments may cause premature failure of electronic components. Do not
use these actuators where explosion proof equipment is required.
Duty Cycle:
Exceeding the 75% duty cycle rating of the 5610/5616 series
actuators will cause premature failure of the motor and/or electronic boards.
The motor should not move for at least 25% of the time (or typically 15
seconds of each minute).
Fluid Media:
The valve materials of construction should be compatible
with the media (fluid) flowing through the valve. This would include all wetted
parts or parts in contact with the media. Contacting the manufacturer of the
fluid or consulting a media compatibility guide may be helpful. Ball valves and
butterfly valves generally require good clean flowing media.
Pressure:
Valves must operate within the pressure rating as listed in the
specifications. The pressure rating is typically the highest non-shock working
pressure allowed within certain temperature limits. Reference the P/T chart
(pressure/temperature chart) to confirm the valve will operate within the
required pressure and temperature limits.
Fluid Velocity:
The fluid velocity should not exceed certain limits to help
avoid excessive noise, shock and damage to the piping system, seals and
valves. Typically, the maximum velocity of the fluid flowing through Valworx
metal valves should be less than 10 feet/second (3 m/s). The maximum
velocity for plastic valves should be less than 5 feet/second (1.5 m/s).
