STARD GEARS outlines double-acting pneumatic actuators for valve automation

STARD GEARS is promoting its LSP series double-acting pneumatic actuators for industrial valve automation, with thrust up to 380 kN and strokes up to 610 mm. The company says the line is aimed at rising-stem gate, globe and control valves, with temperature, override and accessory options for demanding plant conditions.

Why it matters: - Industrial valve automation depends on actuator force that stays consistent across the full stroke, not just at the start and end points. - STARD GEARS is positioning the LSP series for plants that need bidirectional thrust, tight shut-off and regulated positioning in pipeline service. - The product line is built to cover a wide range of valve sizes and operating conditions with one actuator family.

What happened: - STARD GEARS introduced double-acting pneumatic actuator solutions for industrial valve automation. - The LSP series uses air supplied to both sides of the piston to deliver bidirectional thrust. - The actuators are designed for rising-stem gate, globe and control valves. - The company says the LSP series delivers up to 380 kN of thrust and strokes up to 610 mm. - The company directs users to more information for sizing support and product details.

The details: - The LSP series uses a modular linear pneumatic piston architecture for cut-off and regulating duties. - Direct air-driven thrust reduces mechanical losses associated with rotary conversion setups. - Working pressure for the LSP series ranges from 3 to 10.5 barg. - Cylinder diameters go up to 900 mm. - Low-friction seals and an optional chrome-plated cylinder are used to reduce sliding resistance and wear. - The standard sealing package covers temperatures from -20°C to 100°C. - Internal component upgrades extend the range to -40°C or 204°C. - A side-mounted handwheel manual override is available between fully open and closed positions. - The override can use a screw mechanism, mechanical gearbox or hydraulic system, depending on actuator size and space. - Positioners, solenoid valves, limit switches and air preparation units must match the actuator pressure rating and control logic. - Delivery packages can include dimensional outlines, interface drawings, formal calculations, test reports and export compliance documents.

Between the lines: - STARD GEARS is drawing a clean line between linear thrust actuators and quarter-turn Scotch Yoke actuators for ball, butterfly and plug valves. - That split signals a focus on matching actuator type to valve motion rather than forcing one platform across multiple applications. - The emphasis on thrust curves, air consumption and storage suggests the sizing process is as important as the hardware itself. - The manual override and temperature range options point to industrial buyers that need uptime in harsh or interruption-prone environments.

What's next: - Automation engineers and procurement teams can submit bidirectional load requirements and operating frequencies for sizing confirmation. - Buyers will need to define valve type, stroke length, air pressure, ambient temperature, stroking time, cycle frequency and installation direction before final approval. - Plants planning new installations or retrofits may evaluate the LSP series alongside their control accessories and documentation requirements.

The bottom line: - STARD GEARS is pitching the LSP series as a configurable double-acting actuator platform for plants that need reliable two-way force, broad temperature coverage and installation-specific options.
