VA8 Valve Actuator
|
| Capable
of generating up to 8 inch-pounds of torque, the VA8
is ideally suited for metering valves, small needle valves,
small ball valves and teflon valves. The VA8
also makes an excellent alternative to solenoids.
The
microprocessor-controlled motor guarantees optimum torque
control when starting, running or stopping valve rotation.
The VA8 assures accurate valve seating
without stiction or motor stall.
When
supplied by the factory coupled to an associated VK8
Valve Kit that meets your flow criteria, the assembly
comes fully tested and ready for installation.
