YFL Pneumatic angle control valves are used to change the flow direction and solve problems of flashing and cavitation. They are also suitable for medium with high viscosity and granular solids.
YFL Pneumatic angle control valves have different kinds of bonnet type for different temperature range as follows:
1. Standard Type：Cast Steel ：-20～250℃ Stainless Steel：-40～250℃
2. Fin-Extension Type：Cast Steel：-29～425℃ Stainless Steel：-40～450℃
3. Low-Temp. Type：Cast Stainless Steel：-60～-100℃,-100～-200℃,-200～-250℃
The operation of the angle control valve can be pneumatic or electric.
For pneumatic diaphragm actuator, there are two control types: air to open and air to close.
