| Relief pressure valve of proportion expression |
| Type of the products: Y13X-10/Y43X-16 |

Product introduction :
Use the hydraulic pressure principle to control regulating , of simple structure
Proportion of reducing pressure is accurate, pass through in large flow
Reduce and move and press, reduce and press quietly too
Operating steadily has no noise , not shakes , subdues water hammer , protects the pipe network
Suitable for the wanton angle to install
Light , small , install maintaining and convenient |
Operation principle :
Under the function of inlet pressure P1, float piston push open , the medium is passed. Pressure after the pressure caused because the piston both ends section is accumulated differently has changed the valve badly, that is to say in a situation that the pipeline had the pressure , the area of both ends of the piston compares with pressure after the valve after forming the valve. No matter how changes of pressure that in front of the valve , press and move to press and can be reduced quietly to corresponding pressure value pro rata after the valve.
