Maria Valve
1 / 5
Pneumatic butterfly valves use compressed air to drive the actuator, rotating the butterfly plate 90° to control switching or flow regulation. Featuring compact size and good sealing, they are ideal for petroleum, chemical, and water treatment industries.
Characterized by simple structure, light weight, and quick operation. Available in both soft and hard seals to suit various flow resistance requirements and automation needs.
Simple structure, rapid labor-saving opening/closing, and low fluid resistance. High adaptation to high temperature and corrosive media. Suitable for modern industrial fields requiring high efficiency and remote operation.
Widely used in petrochemical, power, food and beverage, pharmaceutical, metallurgy, papermaking, and HVAC for liquid, gas, and powder media control.
