Audited Supplier The FGP4X composite high speed exhaust valve can prevent the float ball from being blown up in the high speed air flow and blocking the exhaust port, resulting in the failure of the exhaust valve. In order to prevent the valve port from being blocked by blowing, the traditional high speed intake and exhaust valves are equipped with protective cylinder at the inlet, which makes the valve structure complicated.
1, high speed exhaust when filling water, not afraid of blowing blocking.
2. high speed suction when water discharge.
3. trace exhaust under normal pressure.
FGP4X composite high speed exhaust valve is a kind of float ball type exhaust valve manufactured by Bernoulli theory, which can keep fully open under the airflow. When the solid water column rises, the float ball can be floated immediately and the exhaust port is tightly closed. Floating ball diameter of the valve adopts the specific, making it the airflow power can maintain float in the air after the opening (suspension), solid water rises the buoyancy can make it up again, with the entrance to a right Angle cone, can do it no matter how much pressure, air velocity, vent will not be blocked.
