Q:What's the W in the check valve H44W?
W represents the sealing surface is the body seal, that is, directly from the valve body out of the sealing surface
Q:Is it necessary to install a check valve in the piston refrigeration compressor?
Following chart:Turn left and turn right | Such arrangements because when the piston machine more than 2 units installed on the same system, if there is a part of the unit stops working in another part of the unit, it will cause the exhaust side wall will refrigerant condensation in the exhaust no work unit tube, the liquid refrigerant condensation along the exhaust the accumulation of down pipe in the exhaust pipe, may cause the cylinder inlet fluid or startup are high pressure, easy to cause the damage of the compressor. Therefore, when multiple compressors are connected in parallel, the check valve must be installed at the top of the exhaust pipe. Not only the piston machine, screw machine should also be installed in the exhaust pipe, otherwise the oil inside is all refrigerant liquid, leading to running oil, there have been such problems in the project.
Q:The difference between swing check valve and lift check valve
Standard light valve professionals answer the difference between the lift check valve and the swing check valve:Lift check valves: check valves slide along the vertical centerline of the valve. The lift check valves can only be installed on the horizontal pipe.
Q:Should the flue check valve be made by the civil team or the installation team?
Internal construction, check the inner ring outside the cement glue installed
Q:Check valve does not automatically check back, how to adjust?

The same thing, the different name, the appraisal finishedPrices vary greatly, probably due to specifications, material, performance and other differences
Q:Pump adapter need check valve?

H- check valve, 4 flange connection, 4 spiral structure, Y- sealing surface material is hard alloy. 160 table nominal pressure 16MPa
Q:What is the function of the stop valve and check valve installed on the water supply pipe?
The check valve belongs to an automatic valve, whose main function is to prevent the backflow of medium, prevent the reverse of pump and drive motor, and release the container medium.
