QJLH Three in One Control Valve:

Multi functional control valve, three in one check valve

1、 Non water hammer check valve function
1. Even if the pump outlet pressure is low, the valve can still be lifted. And let the fluid pass through, starting from 0.04 to 0.07 kgf/cm2.
2. When the fluidity of the fluid is weakened due to the stop of operation, the valve disc is closed by the spring action, which can completely prevent water hammer caused by backflow in general check valves.
3. Three check valves, with their gaskets made of synthetic rubber, can absorb the impact generated when closing the valve and completely seal it.  

2、 Gate valve and globe valve function
Use the valve stem to push the valve disc downwards and tightly adhere to the valve seat, completely preventing fluid flow. Generally, gate valves are made of metal contact, so it is impossible to form a complete seal, while three in one check valves can be completely sealed because their valve discs are made of nitrile rubber.  

3、 Balance valve function
By adjusting the opening of the disc with the lever up and down by hand, the flow rate of the fluid can be adjusted. Using an indicator, the opening and closing status of the valve disc can be observed,


4、 The main structural dimensions and flange geometric dimensions refer to JB81-59 standard
