The design characters of wafer type duo check valve
Check valve is used for preventing the back flow of medium in pipelines and equipments. It will open and close automatically by the pressure of medium. When the medium is back-going, valve disc will close automatically to avoid accidents.
1. Tightly sealed, without leakage under the water pressure testing.
2. Economical, light weight, compact design-significantly lighter and less expensive than comparable swing check valves.
3. Easy to install and maintain.

The perfomance of wafer type, Duo check valve
1. Nominal Diameter: DN40-DN1200
2. Nominal Pressure PN (MPa): 1.0, 1.6, 2.0, 2.5
3. Testing pressure (water) Ps (MPa)
4. Body seat: 1.5 times rated pressure
5. Seat test: 1.1 times rated pressure

Q:Can the check valve be horizontally installed?: Lift check valve can be divided into straight through and vertical two. Straight through lift check valve can only be installed in horizontal pipe, vertical lift check valve is usually installed in vertical pipe.

Q:The working principle and structure description of the mute check valve: Slow closing check valve and check valve or check valve, its role is to prevent the media back in the pipeline, its working principle is as follows: first, the role of principle: moving through the cylinder plug on the valve flap, assist the rapid opening and closing to the sealing surface two, structure 1 structural forms: swing type 2 single disc drive mode: 3 butt welding connection: open and closed by a pneumatic device to control the butt welding of the 4 valves, speeding up the valve opening and closing speed.

Q:Is the check valve and relief valve something?: Not the same thing!!! Installed on the water heater will not have too much money, less than 10 should be enough, but most of the water heaters are non - targets, may not be too good to match, you'd better go to a larger plumbing market

Q:What is the function of the ventilator's check valve?: The utility model relates to a flue check valve, which belongs to an automatic valve, and the main function of the utility model is to prevent the backflow of oil smoke, and only to flow in one direction, and to block gasFlow in reverse direction. When the soot exhauster starts to work, the air flow with the oil smoke pushes the one-way smoke valve through the air inlet and the flow guiding curved surface, and the soot is discharged into the public smokeWhen the soot exhauster stops working, the one-way valve plate is automatically closed under the action of gravity, and the fume passage is isolated from the common flueThe smoke in the flue doesn't flow back in.

Q:What are the types of check valves?: Taiwan reasonable, this may not have domestic, if you can name, you can call three one-way valve, we can see in accordance with the structure of the spring type.Front Ze valve provides: hope to adopt!!!I hope I can help you.

Q:Which side of the gate is the fire check valve in the pump room?: The check valve is installed between the shock absorbing flexible joint and the water outlet control valve at one side of the water outlet pipe of the water pump

Q:What's the difference between a throttle valve and a check valve? Are they the same?: The check valve is directional, so it should be clear when installing. It is like a swinging door that opens in one direction or closes on the other. When the liquid flows towards the opening, the door opens, and when it is stopped, the self pressure of the liquid passing through the door closes automatically and acts as a hindrance to the flow of liquid.Throttle is simple, water switch is one of the throttle valve.

Q:Butterfly micro stop type check valve HH46XP-10Q, what does the letter mean?: Do not know what you say is the manufacturer of valves, in general, many models are manufacturers themselves according to the specifications of their products set.

Q:How can the lift vertical check valve be distinguished from the lift horizontal check valve?: 1, vertical lift check valve should be installed on the vertical pipe. 2, lift type horizontal check valve should be installed in the horizontal pipe.Vertical lift check valve, also known as vertical check valve;Lifting horizontal valve check valve, also known as horizontal check valve.Lift check valve: check valve sliding along the vertical centerline of valve body, lift check valve can only be installed on horizontal pipe,Disc can be used in high pressure small bore check valve. The valve body of the lift check valve is the same as the cut-off valve (which can be used with the stop valve), so it has a large coefficient of fluid resistance. The structure is similar to the cut-off valve, the valve body and the disc are the same as the cut-off valve. The lower part of the upper valve and the valve cover processing guide sleeve, the valve in the valve lift free guide simple simple light driven, when the medium downstream, the valve by the media force open, when the media stopped flow, the valve by the self vertical landing on the seat, preventing the media from the upstream effect.Through lift check valve, the direction of inlet and outlet of medium is perpendicular to the direction of valve seat passage;Vertical lift check valve, the direction of its medium inlet and outlet passage is the same as that of valve seat passage, and its flow resistance is smaller than straight through.

Q:What does "H" for H42W check valves mean?: H: Valve code, is the check valve code, 4: connection mode is flange connection; 2: valve form is vertical lift; W: sealed form, on behalf of the body of the sealing surface
