reversing seat valve
reversing seat valve
Summarize
This reversing valve is a kind of sanitary level single seat pneumatic operating valve,and has wide application in beverage production,pharmaceutical and fine chemistry industry.
•This seat valve is automatically operated by single action or double action pneumatic actuator.Compressed air pushes shaft to locate valve opening or closing position.180 degrees rotation of actuator cylinder ensures valve Normally-open and Nommally-close type.
•Standard type is Normally-close valve (NC),valve can be changed into Normally-open type (NO)through simply changing the piston of pneumatic actuator.
•Sanitary design based on 3A standard:360 degrees adjustment for pipeline exit direction;opening window is used to view and check shaft sealing condition.Internal parts can be simply dismantled through loosening clamp.
•Drive type:manual operation,pneumatic operation,pneumatic power(with position sensor).pneumatic power(with intelligent controller)
