Q:What is the difference between the H44H check valve and the H41 check valve?: The lift type horizontal check valve shall be installed on the horizontal pipeShanghai reliance Valve Manufacturing Co., Ltd.Lifting type is more swing type, good sealing, large resistance to fluid, horizontal should be installed in the horizontal pipe, vertical mounted on the vertical pipe;Swing type check valve installation location is not restricted, it can be installed in horizontal, vertical or inclined pipeline, such as installed in the vertical pipe, the flow direction of medium to bottom up; x0d

Q:What does the check valve "H41F" mean?: According to the provisions of the JB/T 308-2004 valve type programming method:H== check valve4== connection: flange type1== structure form: lifting typeF== sealing surface material: fluorine plastic

Q:What does the number 16 on the check valve mean?: This is the pressure level of the valve, which represents 16Kg, which is used for piping pressure less than this pressure.

Q:Can the swing check valve stand upright?: Swing check valve, vertical mount, horizontal loading can be.

Q:What is the air pipe check valve?: The air pipe check valve is installed in the ventilation or air conditioning duct. When the fan is running, the valve is opened and the air flow is passed smoothly. When the fan stops, the valve is closed to prevent the air from reversing.

Q:I would like to ask you the following questions: Recently, the newly purchased three Lin electric water heater, installed in the upper layer of the five bathrooms, a faucet, that is left to wring out hot water, to the right to wring out cold water, mixed type.1 when there is no safety valve, the hot and cold flow is normal, but the check valve is dripping.2 manufacturers said that the high level to safety relief valve, dripping water and this also concerned, it took more than 100 safety valve, on the cold water pipe, but since then, hot water flow and its small, cold water normal, the check valve is still dripping.3 excuse me, check valve, check valve, safety valve is not a thing? Is it just a different name?4 is the relief valve the same as the relief valve?Now it's really a tough one. How do you solve the problem of small drop of water and hot water flow? The manufacturer said the pressure, but I very cold water washed!Thanks for the answer!: Check valve and check valve is to prevent backflow of water, the valve is used for pressure relief, when the water heater pressure is too high, the pressure through the pressure relief valve and pressure relief valve on the other: for water, the quality is not good, the main problems for the water pressure is too low to cause, and check valve and pressure relief valve will further reduce the pressure, you can try to check off a try, I think the check valve is useless. If not, just add a booster pump to the cold water inlet.

Q:Use of fire pump adapter even before you install a check valve: Multifunctional pump combination device usually comes with safety valves and check valves, usually in the flange pipe interface or who is interface settings simple check valve, safety valve is white, but does not apply to the north, the northern cold, need to separate the pipes below plus a check valve, a higher temperature of the South may be suitable for direct use of non frozen.

Q:What are the differences between the vertical check valve and the horizontal check valve?: The structure principle is the same, but the cost and volume are different, there is nominal pressure difference, the use place is different

Q:Why is the water ring vacuum pump equipped with check valves?: The check valve is a one-way valve, the instantaneous vacuum of the stopping pump is higher than the pump cavity, and the gas enters the pump cavity from the exhaust port, and the water pressure is connected to the vacuum pipeline, and the function of the check valve is to prevent water from entering the pipeline
