Working principle
In the non-operating state, the valve is normally closed (open) due to the spring force. When the actuator piston is acted upon by the compressed gas, the valve opens (closes). The double acting form controls the valve switch by means of compressed gas.

Characteristics
1, large fiux, low resistance, no water hammer
2, Y-type design, increase 30% flow
3, long life
4, valve stem automatic correction, self-lubricating, maintenance-free
5. The cylinder is made of stainless steel, which is more excellent in harsh environments and can be rotated 360°.
