Customization:
With a corrosion-resistant stainless steel body, ensure long-term durability in water-based applications while resisting rust and chemical wear. This outperforms standard steel or plastic actuators in harsh industrial environments.*
With red and white control knobs and indicator lights, operators can manually adjust valve positions and monitor real-time status instantly. This simplifies troubleshooting compared to models without visible status indicators.*
With electric power and compatibility with medium-pressure water systems, achieve precise, consistent control without reliance on compressed air. This reduces downtime compared to pneumatic actuators in low-pressure environments.*
Direct mounting eliminates the need for additional brackets or adapters, streamlining installation in tight industrial spaces. This saves time and costs compared to flanged or bolted alternatives.*
Stainless steel construction aligns with common safety and hygiene standards for water systems, ensuring compliance with industrial regulations. Verify certifications (e.g., NSF 61) directly with the manufacturer for specific applications.*

⭐⭐⭐⭐⭐ James Whitaker - Water Treatment Plant
"Installed the ST14+RS400 Pro Model in our coastal water treatment facility six months ago. The IP68 rating and 316 stainless steel body have held up flawlessly despite constant exposure to salt-laden air and humidity. We’ve had zero corrosion, and the manual override saved us during a recent power outage—operators were able to maintain flow without delay. Remote control integration with our SCADA system was seamless."Purchase Date: May 2024 | Usage Period: 8 months
⭐⭐⭐⭐⭐ Lena Park - Building Automation Contractor
"We’ve used the Advanced Model across three commercial high-rises with complex HVAC networks. The direct-mount design cut our installation time by nearly 40%, and the blue finish makes it easy to locate and inspect in crowded mechanical rooms. Torque is more than sufficient for the butterfly valves we typically work with. Plus, the red/white status lights are a small feature that makes troubleshooting so much easier."Purchase Date: February 2025 | Usage Period: 5 months
⭐⭐⭐⭐☆ Carlos Mendez - Agricultural Infrastructure
"Deployed the Base Model on a large-scale irrigation control system last year. So far, performance has been solid—electric operation is reliable, and we appreciate not having to run pneumatic lines across remote fields. The only reason I’m not giving five stars is that initial setup required a bit more calibration than expected. That said, after configuration, it’s been ‘set and forget.’ Great value for automated water control."Purchase Date: November 2024 | Usage Period: 10 months
⭐⭐⭐⭐⭐ Fiona Reynolds - Chemical Manufacturing Plant
"We needed an actuator that could handle fluctuating pH levels and medium-pressure water lines in a corrosive environment. The ST14+RS400 Advanced Model with 316 stainless steel has exceeded expectations. No signs of degradation after seven months of continuous operation. NSF 61 certification gave us the green light from compliance, and the ability to customize the color (we went with high-visibility yellow) helped align with our safety zoning."Purchase Date: April 2025 | Usage Period: 4 months
⭐⭐⭐⭐⭐ Amir Hassan - Industrial Retrofit Specialist
"Used the Pro Model to retrofit aging manual valves in an offshore-support facility. The 52 Nm torque easily drives larger butterfly valves, and submersion resistance (tested during a flood drill) proved the IP68 claim. Custom mounting brackets were engineered quickly by the supplier’s team—this flexibility made integration into legacy systems painless. This is the most future-proof actuator I’ve installed in years."Purchase Date: January 2025 | Usage Period: 7 months

Dr. Evelyn Torres - Industrial Automation Consultant
"The ST14+RS400 series stands out in the mid-range electric actuator market due to its balanced design—robust materials, intelligent fail-safes, and real-world adaptability. For water-based systems requiring compliance with NSF 61 and ISO 5208, this actuator is a top-tier choice. I particularly recommend the Advanced and Pro Models for facilities in aggressive chemical or marine environments."
