We can adjust the pressure by adjusting the nut or stem in the scale sleeve, and the valve setting rate from 5kpa-35kpa , each setting 0.5 on sleeve pressure change 2.15Kpa, If the scale is 3.5, the pressure drop is 15.75Kpa. the details please check the table
Warning notices
The valves must be installed for the correct application using clean fittings. strainer should be fitted to prevent impurities.
Test points
Two test points are fitted next to each other. This arrangement ensures the best accessibility and optimal connection of measuring devices in all installation positions
More Details please sent Email to to request for the catalogue.
Quality Control
Hot forge
Our brass valve is produced by forging, through forging the valve product strength is greater, no porosity, can effectively prevent the leakage of the valve body.
CNC Machining
Our products are processed by precision CNC machine tools, with high machining accuracy up to 0.1 micron. We have machining centers to meet customers' requirements for products with high coaxiality
Machining Inspection
In our machining process, each size needs to be strictly tested. Workers will conduct a self-inspection of their products every 2 hours, and QC will conduct a workshop inspection every 2 hours to ensure that the size of products fully meets the requirements of the drawings
Assembly Room
Our assembly shop USES the assembly line, the result of teamwork can guarantee the output of a large quantity of products.100% of the products on the production line need to pass the leak test. We use the pressure of 6-8bar to test each product. Only after passing the test can the products be packed into cartons.
