AUMA TIGRON TR-M Multi-Turn Actuator (High Torque)

Overview: A Modern Platform for Rising-Stem Valve Automation

The AUMA TIGRON TR-M Multi-Turn Actuator carries out a classic actuator mission – automating gate valves with or without rising stem, as well as double block and bleed valves – through a modern actuator platform built for precision, modularity, and wide operating range. Rising stems pass through the TIGRON’s hollow shaft, which drives the stem thread directly, while a stem protection tube shields the stem from contamination and protects personnel from injury, a design detail that supports virtually unlimited stroke length for valves with long travel requirements.

As an authorized supplier of AUMA valve actuators, Seven Star LLC sources and supplies the TIGRON TR-M multi-turn actuator to refineries, gas processing plants, and process industries across Oman and the wider GCC. Because TIGRON’s modular gearbox compatibility extends its reach well beyond simple gate valve service, Seven Star LLC helps engineering teams specify the right TIGRON configuration – standalone or combined with a gearbox – for their specific valve automation project.

Working Principle: Precision Sensing Across a Wide Torque and Speed Range

The TIGRON drives the valve stem thread through its hollow shaft, with a Combi-Switch providing optimized operation by combining limit and torque sensing functions in a single integrated device. Limit sensing supports up to 5,000 turns per stroke, accommodating valves with very long travel requirements, while torque sensing covers the full 0 to 100% of maximum torque range, giving precise control over seating force and protecting the valve seat from over-torquing at both open and closed end positions.

TIGRON actuator versions are available for both open-close duty and modulating duty, and the actuator’s wide-range power supply unit accommodates varying site voltage conditions without requiring a separate voltage-matched transformer. This combination of precision sensing and flexible power input makes the TIGRON well suited to both straightforward isolation valve duty and more demanding continuous control applications on the same core actuator platform.

Engineering Design of the TIGRON TR-M

The TIGRON is rated IP68 and covers a torque range of approximately 30 to 1,000 Nm with output speeds up to 216 rpm, and an exceptionally wide ambient temperature rating from -65°C to +75°C, supporting installation in extreme cold as well as hot desert environments. A handwheel provides manual operation for commissioning, maintenance, and emergency positioning independent of electrical power.

The TIGRON’s modular AUMA scheme allows it to be combined with any of six AUMA gearbox type ranges, extending its application well beyond standalone gate valve automation. Combined with GK bevel gearboxes or GST spur gearboxes, torques up to 16,000 Nm can be reached, while pairing with AUMA part-turn gearboxes extends TIGRON’s reach to butterfly valves and the ball valves common in oil and gas industry applications requiring roughly 90-degree part-turn movement. AUMA linear thrust units can further convert TIGRON’s multi-turn output into the thrust movement required for globe valve automation, making TIGRON a genuinely universal actuator core across multiple valve types.

Key Features

The AUMA TIGRON TR-M Multi-Turn Actuator delivers precision, modularity, and wide environmental range. Key characteristics include:

• Virtually unlimited stroke via hollow-shaft rising-stem drive with protective stem tube.
• Combi-Switch combining limit sensing (up to 5,000 turns per stroke) and torque sensing (0-100%) in one device.
• Open-close and modulating duty versions available on the same platform.
• Wide-range power supply unit accommodating varying site voltage conditions.
• IP68 protection with an exceptional -65°C to +75°C ambient temperature range.
• Modular compatibility with six AUMA gearbox ranges, extending reach to part-turn and linear valve types.
• In combination with GK or GST gearboxes, torque capacity extends up to 16,000 Nm.

Industrial Applications

The TIGRON TR-M is deployed for gate valve and double block and bleed valve automation across refineries, gas processing plants, and pipeline infrastructure, and – through its modular gearbox compatibility – extends to butterfly and ball valve automation in oil and gas applications and globe valve automation via linear thrust unit combination. Its wide ambient temperature range makes it particularly suited to Gulf-region installations spanning extreme summer heat.

Seven Star LLC supports refinery instrumentation teams, gas processing operators, and EPC contractors across Oman, Muscat, Sohar, and the broader GCC region with sourcing of AUMA TIGRON actuators, helping projects standardize on a single modular actuator platform across multiple valve automation needs.
