Control valve is made up of pneumatic multi spring diaphragm actuator and lower flow resistance straight single seat valve(sleeve). The single valve is connected directly with its guilding structure on the cap; with its corn is ram structure, which is smaller and lighter than normal single seat valve and its flux is bigger than normal sleeve valve. It is widely applied in industry process and automatic controlling system.
