The Farab electric and manual diaphragm control valve model DLG16 is designed for precise flow regulation in water, steam, oil, and industrial fluid pipelines. The body is made of ductile iron GGG40 with a nominal pressure rating of PN16, and the diaphragm is EPDM or NBR for temperature and pressure resistance. The stainless steel stem and seat ensure reliable sealing, while the diaphragm mechanism provides leak-free operation under variable pressures. The valve features an electric actuator with position control and an emergency manual override. Flanged ends comply with EN 1092-2, and installation dimensions follow DIN 3202. Operating temperature ranges from 0–120°C, and the valve is rated for up to 16 bar.
The Farab DLG16 diaphragm valve provides flexible and precise flow control with minimal pressure drop. The electric actuator is equipped with position sensors and electronic control for accurate diaphragm positioning. The diaphragm is replaceable and designed for long-term operation under harsh industrial conditions. The body design allows easy access for maintenance and diaphragm replacement. Each valve undergoes hydrostatic and leakage testing according to API 598 standards to ensure precise performance, durability, and safe operation in industrial systems.

For safe installation and operation of the Farab DLG16 diaphragm control valve, the pipeline must be fully drained and system pressure reduced to zero to prevent sudden hydraulic impact. The valve must be installed in the direction indicated by the arrow on the body to ensure proper diaphragm function. Using PN16 standard flanges and applying correct bolt torque is essential to prevent leakage. During operation, avoid sudden pressure changes or mechanical impacts on the diaphragm chamber to prevent reduced service life. Routine maintenance, including inspection of the diaphragm, seat, and pressure control settings, ensures stable and safe system performance.
