Vulcanization Seated Butterfly Valves

Vulcanization Seated Butterfly Valves

Vulcanized seat butterfly valve is suitable for different actuators (manual, electric, pneumatic). Zero leakage, more durable and stronger valve spindle. Multi-standard calibration holes are suitable for standard, American standard, British standard, Japanese standard, multi-standard flanges. Pinless connection between spindle and valve plate eliminates the possibility of corrosion failure. The valve seat is vulcanized on hard back to ensure that the rubber is not deformed, and can be used for unique cushioning beveled seat with negative pressure not exceeding 1KG line to realize the effect of eccentric butterfly valve's centerline butterfly valve structure. Double-break valve plate spherical design, service life increased by 15%, to ensure low torque, high flow, long life O-ring seals to prevent media leakage
