STARD GEARS details how its Scotch yoke actuators fit ball, butterfly and plug valves

STARD GEARS says its YP Series Scotch yoke actuators are designed for 90-degree automation of ball, butterfly and plug valves, with yoke geometry matched to each valve type’s torque profile. The company also highlights ISO and NAMUR interfaces, travel adjustment, manual override options and international export experience as part of its supplier pitch.

Why it matters: - STARD GEARS is positioning actuator selection as an engineering match, not a generic sizing exercise. - The company’s pitch centers on matching torque curves to valve behavior for ball, butterfly and plug valves. - The approach is meant to reduce mismatch risk in quarter-turn valve automation.

What happened: - STARD GEARS outlined how its YP Series Scotch yoke actuators support ball, butterfly and plug valves. - The company said the YP Series is built for 90-degree quarter-turn motion. - STARD GEARS published the explanation from Suzhou, Jiangsu, China on August 28, 2026. - The company provided a direct contact link for project selection support: the company’s website.

The details: - The YP Series uses a Scotch yoke mechanism to convert pneumatic piston motion into rotational output. - A Symmetrical Yoke is designed for the more balanced torque demands of ball valves and plug valves. - The Symmetrical Yoke is intended to align with opening, running and reseating phases across the full 90-degree stroke. - A Canted Yoke is aimed at butterfly valves. - The Canted Yoke delivers high starting torque and lower running torque. - STARD GEARS says that profile is useful when butterfly valves face high differential pressure, difficult media or aggressive seating conditions. - The YP Series includes ISO connecting dimensions. - The YP Series includes NAMUR standard mounting holes. - The actuator offers ±5-degree travel adjustment for end-point tuning. - Manual operation options include a screw rod, a mechanical handwheel gearbox and a hydraulic manual override. - STARD GEARS says its products have been exported over the past decade to the United States, Italy, Germany, Mexico, Singapore, Japan and other countries. - Standard fulfillment uses export packaging. - Non-standard packaging can be arranged for specific projects. - Shipping costs vary based on express or sea freight, quantity, weight and transportation method. - The post also included social links to LinkedIn and YouTube.

Between the lines: - The release is as much a procurement guide as a product note. - STARD GEARS is trying to frame the buying decision around valve torque data, interface standards and installation needs. - That positioning can matter for industrial buyers managing cross-border projects and custom requirements.

What's next: - Buyers are expected to start with valve type, torque curve, interface needs and manual override requirements before requesting a quote. - STARD GEARS says final actuator matching should be based on the valve’s actual torque curve at the specified differential pressure. - The company is directing prospective customers to submit project details for YP Series selection support.

The bottom line: - STARD GEARS is selling the YP Series as a matched-fit solution for quarter-turn valve automation, backed by torque-curve selection, standard interfaces and export support.
