The white iron check valve of Dolomann is an oil return check valve installed in the air-oil separator of air compressor. It is made of SUS304 stainless steel, which has a good temperature resistance, is not easy to deform and has low failure rate, ensuring the oil returning, avoiding invalid gas consumption and improving the efficiency of air compressor.
Dolomann's white iron check has various size, which can be matched by customer themselves' inquiry, and accept customized services of different size and material.
Dolomann has been deeply involved in the field of air compressor for 30 years, and has won ISO 9001 certification, with guaranteed quality.
White Iron (Stainless Steel) Check Valve
Features
Dolomann's white iron check valve can prevent the fluid from flowing back when stop the air compressor and the pressure drop to 0 Pa.
- Oil Resistance.
- High Temperature Resistance.
- Maximum Withstand Voltage: 30kh/cm²
- Starting Pressure: 0.2 ~ 0.3kg/Cm²
- Acid and Alkali Resistance.
- Prevent Fluid Back Flow.
Functions
If the air compressor stops due to failure or power cut, there is not enough pressure to push the compressed air. At this time, the compressed air in the air storage cylinder of the air compressor may flow back to the cylinder due to the difference of air pressure, which will affect the compressed air in the cylinder. In order to prevent air or other impurity from flowing backwards, the compressed air is limited in the air storage tank by the check valve of the air compressor. The check valve can avoid air backflow in the pipeline and harm to the interior of the compressor.
