1. Shutoff function: when the inlet pipeline stops pressure supply or overhaul, to ensure that there is no leakage in the pressure behind the valve, the cut-off function can be implemented, and the valve rod can be turned instantaneously to push the valve disc to close towards the valve seat.

 

 

 

2. Throttling function: In order to ensure that the pressure and flow at the back of the valve meet the design requirements, the flow adjustment function can be implemented. Instantaneous rotation of the valve rod reduces the flow and pressure, and counterclockwise rotation of the valve rod increases the flow and pressure. At the same time, the fine adjustment can be carried out according to the upper scale of the valve rod and the pressure gauge at the front and back of the valve (for transportation safety, the pressure gauge is generally not provided. If the user wants, please specify it in the contract).

 

 

 

3. Check function: during temporary shutdown or pressure shutdown, prevent the backflow of pipeline pressure fluid from damaging the equipment in the pipeline or ensuring the pressure behind the valve. At this time, the fluid behind the valve has not formed the backflow impact force. The valve spring has already pushed the valve disc to close the check, effectively controlling the water hammer impact during the check.

 

 

 

4. Interchangeable function of straight-through and angle-type installation: if the straight-through type is changed to angle-type installation, the angle-type installation can be realized by removing the connecting bolts of the inlet valve body and the outlet valve body, and turning the inlet valve body 180 degrees (if the user needs the valve body to have the interchangeability function or with the 11AB screw hole of the pressure gauge, please indicate it when signing the contract).

 

 

 

5. JLH stop, throttle and check multi-function valves completely replace the three valves that must be installed at the same time in the traditional pipeline device. The average price is 50% lower, the volume is 65% smaller, and the weight is about 65% lighter. It is a new product with energy saving, capital saving, and a lot of space reduction.
