Electric Actuator with Diaphragm Valve
Electric Actuator with Diaphragm Valve – 9850 Series
The Electric Actuator with Diaphragm Valves (9850 Series) from SUDE Engineering Pvt. Ltd. delivers precise, hygienic, and fully automated flow control for critical process applications.
Designed with a high-purity SS316L diaphragm valve and a robust electric actuator, this solution ensures complete isolation between the actuator and process media. The diaphragm-sealed design eliminates dead zones, prevents contamination, and guarantees reliable performance in CIP/SIP systems, WFI loops, purified water lines, clean steam, and sterile fluid handling.
With options for on/off or modulating control, tri-clamp or spigot ends, and automation accessories, the 9850 Series is ideal for modern, automated process plants.

Design & Construction:
Designed with a high-purity SS316L diaphragm valve and a robust electric actuator, ensuring complete isolation between actuator and process media. The diaphragm-sealed design eliminates dead zones, prevents contamination, and supports hygienic processing requirements.
Working Principle:
Electric Actuation Control
The electric actuator receives a control signal to precisely open or close the valve, ensuring accurate and automated flow regulation.
Advanced Diaphragm Sealing System
A flexible diaphragm seals tightly against the valve seat, preventing leakage and maintaining consistent performance.
Sterile & Reliable Flow Operation
Complete isolation of the actuator from the process media ensures leak-free, hygienic, and dependable flow control in sensitive applications.
