Factory‑direct GRAT WA‑20 IoT mini electric actuator provides reliable, smart valve automation for liquid cooling, HVAC, water supply‑drainage and ventilation projects with high cost‑performance for small‑and‑medium automation projects.

GRAT Marine Quarter-Turn Electric Actuators suit vessel intelligent retrofits, delivering stable operation against salt spray and vibration while enabling precise remote control and fail-safe emergency shutdown.

For ball valves on high‑low‑temperature alternating test benches, sticking during opening‑closing operations is mostly caused by dimensional deformation of valve seats resulting from thermal expansion and contraction. For working conditions with a wide temperature range of ‑40 °C to 135 °C, sticking faults induced by seat deformation can be resolved by prioritizing valve seat materials with excellent thermal stability combined with structural optimizations.

GRAT IP68 electric actuators are your top pick for devices exposed to tough conditions: underwater submersion, outdoor rainfall, humid and dusty surroundings. Every actuator passes standardized air tightness tests before delivery, boasting stable zero-leak sealing. Built for long-term use in harsh environments, they avoid equipment burnout from water ingress and internal rust issues.

GRAT supplies customized anti-freezing and anti-condensation solutions for pneumatic valves to eradicate winter cold malfunctions and maintain reliable valve operation in cold seasons.

Learn the distinctions, corrosion resistance and applications of 304, 304L, 316, 316L stainless steel valves plus ASTM cast CF series grades for accurate industrial material selection.

GRAT Electric Plug Valve delivers field-proven stability for high-pressure, high-risk, and complex well cementing operations. Rated for working pressures up to 70 MPa, this intelligent electric valve provides remote control, ultra-fast actuation, and reliable bubble-tight sealing in extreme downhole conditions.

The upgraded GRAT control module with four optimizations solves electric actuator on-site wiring and commissioning issues.

GRAT tri-clamp ball & butterfly valves deliver ideal on/off and flow control for sterile erythritol production, solving residue, leakage and automation issues.

Electric hard-sealed ball valves feature excellent temperature and pressure resistance, strong wear and erosion resistance, intelligent control and easy maintenance. They are well suited for the harsh working conditions throughout the entire sulfuric acid and chloride processes in the titanium dioxide industry, serving as key supporting equipment. Widely applicable across multiple sectors, these valves will continue to be optimized to align with the trend of refined, intelligent and eco-friendly industrial development, supporting safe, efficient and low-carbon production in various industries.
