DAV 1204 |
|
The DAV 1204 is a direct acting, normally closed relief valve designed to control air pressure in pneumatic circuits and to protect components from damage. This valve avoids the hazard of developing excessive forces in the system, limiting the maximum pressure by diverting excess air when pressure gets too high. DEL Hydraulics supplies the DAV 1204 Pressure Protection Valve at pre-determined settings from the factory, so no adjustment is needed. However the valve can be adjusted to various pressures. |
The DAV 1204 Pressure Protection Valve protects against the loss of pressure in the primary system caused by a fault in the auxiliary system (as caused by a broken air line) to cause the primary pressure to drop to 60 PSI, the DAV 1204 will automatically close the air supply to the system. The DAV 1204 will not open again until the primary pressure builds back up to 90 PSI. Standard minimum closing pressure is from 60 to 70 PSI. The standard opening pressure is from 80 to 90 PSI. |
