Flowserve linear bases for electric actuators

Flowserve Corporation has developed a linear base that can easily attach to a Limitorque MX or QXM actuator for use in the electrical actuator control and choke valve markets. The Linear Base (LB) products are available in two sizes and can sustain valve thrusts up to 109kN.

The Limitorque LB has been designed for the growing electrically actuated control valve market and offers the unique combination of a separate thrust base and linear base. This permits the user to remove the actuator separately, leaving the linear base and control valve in place, for easy servicing or modification. The LB is designed to comply with EN15714 Electric Actuators for Industrial Valves Requirements, and can be fitted with an optional EN base in either ISO or MSS flanges. Standard stainless steel stems are available to meet customer load and speed requirements and customer specific stems can be manufactured to specification.

Limitorque is one of the first manufacturers with the LB designed to EN 15714 guidelines, and their stainless steel stems can be supplied as an option to meet its corrosion requirements. In addition, to supplement the introduction of the LB, both the QXM and MX modulating capabilities have been increased to a maximum 1800 starts per hour per IEC 60034, S4 rating.
