3/4in12in Special Shut-off Valve with Miniaturized Electric Cast Steel Diaphragm Control Mechanism Explosion-proof Intelligent
Drive method: Powered by an electric actuator (such as a DC motor), enabling remote control and automated operation.
Structural design: Full diameter, unobstructed flow path. The medium flows only through the tube sleeve, avoiding contact with the valve body and preventing contamination and corrosion.
Sealing performance: Achieves bidirectional zero leakage when closed. Even if the medium contains particles, it can still be reliably sealed.
Low maintenance cost: The only vulnerable part is the rubber or plastic tube sleeve. After replacement, the valve performance remains as new, and the valve body can be used for a long time.
Applicable conditions: Suitable for wastewater treatment, chemical industry, mining, food and beverage industries, etc., for handling abrasive or corrosive media such as slurry, acid and alkali solutions, and dust.
