Product Update: Kinetrol VLS Limit Switch Box

VLS Limit Switch Box
After a decade since the launch of the Kinetrol Universal Limit Switch Box it has become necessary to replace the tooling. As a result, Kinetrol has taken the opportunity to make some improvements to the design.

With the continued pressure for modularization and commonality a new precision die cast switch box will offer some positive improvements over the current model, including more internal space for future developments. The new design is known as the VLS Limit Switch Box.

Reduction in Weight. The unit will offer a reduction in weight of the standard 07 version from 2.32 lbs (1.05 kg) to 1.50 lbs (0.68 kg).

All New Plastic Coupling. Improved access to mounting screws for all electronic options for easy actuator mounting. Coupling is permanently retained in the box and does not need removing.

New coupling has a lower Oring which makes all shafts discretely sealed when not mounted. Coupling retainer is replaced with an integral shoulder on the coupling.

All new switch strikers. Common standard strikers for both mechanical switches and proximity sensor activation.

New Standard V3 Switch (004). New V3 switches offers a more defined switch point.

New Mounting for Model 03 and 05. The VLS Limit Switch Box will be supplied as a Model 07 Female Square as standard, (only one size box) which can then be converted with the use of two adaptor options to suit Model 03 and Models 05 Actuators reducing the number of switch box variations distributors stock. SP1620 - Model 03 mounting kit (includes removable plate coupling and fixings) SP1621 - Model 05 mounting kit (includes removable plate and coupling and fixings)

New Standard Conduit Entries. The conduit entries will remain M20 for ISO and 1/2” NPS for ANSI however the land profile has been changed. The additional entries on the four-entry version remain unchanged.

Switch Options. All switch options will be available including the pneumatic switch option (002) except for ATEX approved versions. ATEX Approved switch options (001, 002, 003 and 009) are currently undergoing ATEX testing and will be available later. As a result, these will continue to use the older design ULS.

Please refer to the Kinetrol coding on the VLS Tech Bulletin located on this Kinetrol USA web page.

Modular Concept. These changes will affect the modular approach when fitting the VLS box to Model 03 and 05 actuators. On actuator Models 07 to 15 there is no change. The discrete option for Models 16 to 30 will now utilize SP1602 07/05 reducer and SP1601 Discrete 05 Drive Adaptor offering a price saving over the old design.

VLS Coding. The coding has been changed to reflect the new design by adding a “V” after the U for non ATEX standard options. ATEX switch options (switch type 001, 002, 003, 009) will remain as “0” after the U in the code.
Examples of code change:

  • 097-104U005004M (DA+ULS) becomes 097-104UV05004M (DA+VLS)
  • 077-004U005004M (ULS) becomes 077-004UV05004M (VLS)
  • 077-001U001000 (ULS ATEX) is unchanged

Angle Retransmit and Pot Assembly – The new Angle Retransmit and Potentiometer uses a geared coupling which replaces the standard coupling when fitted. This new design will also offer an additional price savings. The old ULS Angle Retransmit assembly is not compatible to retrofit with the new VLS unit. All other options are unchanged including AS-interface, Terminal Blocks, Multi-Terminal PCB.

Operation of the Kinetrol Model 20 Vane Actuator with Limit Switch

The following video demonstrates the Kinetrol Model 20, double acting, pneumatic vane actuator as it closes a large butterfly valve.

The Model 20 actuator is capable of delivering 89,000 inch pounds of torque at 80 PSI. The unit you see below is equipped with a dual coil, 4-way solenoid valve to control air flow to either side of the actuator, as well as control the opening / closing time. The actuator below also is equipped with a Kinetrol Universal Limit Switch with visual indication and internal electrical contacts.
