Specifications

DYC-JQ series angle-pass electromagnetic vacuum differential pressure type with inflation valve

DYC-JQ series angle-pass electromagnetic vacuum differential pressure with inflation valve is a new type of vacuum valve installed on the air inlet of a mechanical vacuum pump. Its working principle is that the mechanical pump and valve are connected to the same circuit. When the vacuum pump needs to work When the operation is stopped or the power is suddenly cut off, the valve uses the pressure difference between atmosphere and vacuum to push the piston to automatically close the valve, cut off the connection between the pump and the vacuum system, maintain the vacuum degree of the vacuum system, and amplify the air to the vacuum pump to prevent the vacuum pump oil from returning to vacuum The system is conducive to restarting the vacuum pump. When the vacuum pump starts again, the valve uses the spring to push the piston open to open the valve.
The applicable working medium is air and non-corrosive gas.

DYC-Q series straight-through electromagnetic vacuum differential pressure with inflation valve

DYC-Q series straight-through electromagnetic vacuum differential pressure belt inflation valve is a new type of vacuum valve installed on the air inlet of a mechanical vacuum pump. Its working principle is that the mechanical pump and valve are connected to the same circuit. When the vacuum pump needs to stop running due to work , Or a sudden power failure, the valve uses the pressure difference between atmosphere and vacuum to automatically close the valve, cut off the connection pump of the pump and the vacuum system, maintain the vacuum degree of the vacuum system, and amplify the air to the vacuum pump to prevent the vacuum pump oil from returning to the vacuum system, which is beneficial The vacuum pump restarts. When the vacuum pump restarts, the valve uses gravity to automatically drop the valve plate to open the valve.
The applicable working medium is air and non-corrosive gas.

GDQ-J series angle-pass type high vacuum electric dynamic baffle valve

GDQ-J series angle-pass type high vacuum electric dynamic baffle valve is powered by compressed air, and the direction of the air path is controlled by a solenoid valve, which pushes the cylinder piston to reciprocate and drives the reciprocating movement of the valve stem to open or close the valve plate. To cut off and connect the vacuum pipeline, the valve features stable switching and high stability. The cylinder configuration can be reversed to one atmosphere or open in the atmosphere on the vacuum side. In particular, the shaft seal adopts bellows for more reliable sealing and can be used for a long time. Work under frequent switching times.
The applicable working medium is air and non-corrosive gas.
