The control action is flexible, sensitive response, strong wear resistance, especially the pneumatic remote control abrasive valve uses ultra-wear-resistant composite materials, long life, easy flow adjustment, can spray steel shot, steel sand and other large materials.
During sandblasting operation, a control signal is sent to the intake valve and the normally closed abrasive valve, the strong spring in the abrasive valve is flattened under the action of compressed air, the flow regulating tube is opened, and the sandblasting operation begins. As soon as the air control signal disappears, the powerful spring immediately closes the abrasive valve and the abrasive is cut off.
