美国ALSO艾索蝶阀（DOUBLE ECCENTRIC HIGH PERFORMANCE BUTTERFLY VALVES）

The high performance butterfly valve is available in sizes 2" - 24" with a one piece wafer or lug body. Body materials include stainless steel and carbon steel and sealing standards in conformance with ASME 150/300 class rating. Top flange is drilled to ISO 5211 standards and utilize a flexible lip seal concept when disc closes. The true choice in a high performance butterfly valve need - available manual or actuated.

HIGH PERFORMANCE BUTTERFLY VALVE SERIES

The offset disc produces a cam-like action, pulling the disc from the seat. This action reduces seat wear and eliminates seat deformation when the disc is in open position. The disc does not contact the seat when the valve is in open condition, therefore seat service life is extended and torques are reduced. As the valve closes, the cam-like action converts the rotary motion of the disc to a linear type motion effectively push the disc onto the seat.

ASME CLASS 150/300 STAINLESS STEEL BODY RATING

Valtorc valves can be direct mounted with pneumatic actuators or electric actuators and actuator accessories for complete automation options such as far open/close and position controlled. Valves can be mounted with manual overrides.  Valves up to 2" for class 150 and up to 4" for class 300 can be supplied with lever handles for manual operation. Optional accessories for hand-lever operation can be provided for various flow control requirements. Pad locking can also be provided for preventing unauthorized operation
