- Working Principle
The pneumatic three-way valve, which can replace the three-way ball valve to achieve vertical diversion or mixing function, the performance is much better than ball valve,also is a option to work as combine to angle seat valve.
Flow direction 01 ：In the non-working status, C is normal close when the action of spring force, AB circulation, when the actuator is compressed by air, C on, B off, AC circulation.
Flow direction 02 ：In the non-working status, when the action of spring force B normal close, AC circulation(AC vertical),when the actuator is compressed by air, B on, C off, AB circulation.
Flow direction 03 ：In the non-working status, when the action of spring force A B C are all circulation, when the actuator is compressed by air, B on, C off, AB circulation.
Flow direction 04：In the non-working status, when the action of spring force C normal close, AB circulation, when the actuator is compressed by air, C open, A B C are all circulation.
- Features
