Q: Can the swing check valve stand upright?: Ordinary lift check valves shall not be erected. Lift check valves with springs can also be mounted.

Q: Can the check valves fit two in one tube? One up, the other down: Launching, then you'd like to have a Sheung Shui at the front of the Sheung Shui

Q: Which type of check valve should be selected for vertical pipes?: The check valve on the vertical pipeline shall ensure that the spool goes back to its position when the fluid is stationary and reversed.Optional:Butterfly check valves, pipes of low pressureVertical lift check valve, high pressure resistance, good tightnessSwing check valve: flow must be from the next up, the pipe diameter is unlimited

Q: How can the lift vertical check valve be distinguished from the lift horizontal check valve?: The check valve is divided into three kinds: lift check valve, swing check valve and butterfly check valve. The lift check valve can be divided into two types: vertical and horizontal. Swing check valve is divided into single, double valve and multi flap type of three. Butterfly valve for the straight through, the above non-return valve can be divided into connection, flange and welding of three lift check valve and stop valve structure similar to the thread in the form of connection, the valve in a line along the channel for the lifting movement, reliable action, but the fluid resistance is large. Small in diameter for the occasion. Lift check valve can be divided into straight and vertical two kinds. Straight through lift check valve can only be installed in horizontal pipe, vertical lift check valve is usually installed in vertical pipe. You can see the picture in Baidu's picture

Q: What's the difference between the cut-off, check, check, and stop valves three? Better picture,: Stop check valve: when the handwheel is rotated so that the valve stem rises, the disc does not rise together, but only the valve clack is released.

Q: What does the H/F/P stand for in the check valve H41H/H41F/H41P?: Respectively, the valve seat sealing surface is made of alloy / fluorine plastic / stainless steel.

Q: What does "H" for H42W check valves mean?: Valve type codeGate valve ---ZStop valve ---JThrottle valve ---LBall valve ---QButterfly valve ---DDiaphragm valve ---GPlug valve ---XCheck valve and valve ---HSafety valve ---ARelief valve ---YSteam trap ---SConnection form codeInternal thread ---1External thread ---2Flange ---4Welding ---6Yes, clip ---7Clamp ---8Jacket ---9Check valve and valve structure of codeLifting typeA.

Q: Ask questions about the installation of check valves after water meters: Generally installed after the water meter. The main reason: if the water point is higher than the water meter installation position, once the pipe network in the absence of water, the remaining water in the pipeline will flow in the direction of the water meter in turn. This will cause the water meter to reverse and cause damage to the water meter. A check valve is installed after the water meter, so that the situation can be avoided.

Q: Are the gate valves and check valves of the same type?: Check valve is a check valve function, is to prevent the media back, it is by the valve on the pin shaft and the rotary switch to play the role of the valve with different things, when it is opened by medium pressure automatic opening, closing time depending on the medium and back type the self gravity valve closed, it is a kind of automatic gate valve function, does not require an external force is applied to it, it is a demand for the direction.

Q: Installation position of air pipe check valve: Texture of material1. cast iron check valve2. brass check valve3. stainless steel check valve4. carbon steel check valve5. forged steel check valveCheck valve refers to rely on the flow of the media itself and automatically open and close the valve flap, used to prevent the media back flow valve, also known as check valve, Dan Xiangfa, counter flow valve and back pressure valve. 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. The check valve can also be used to provide a supply to the auxiliary system where the pressure may rise above the system pressure. The check valve can be mainly divided into swing check valve (rotating by gravity center) and lift check valve (moving along the axis).The function of this type of valve is to allow the medium to flow in one direction and to prevent flow in the opposite direction. Usually the valve is automatically work, fluid pressure flow in one direction, the valve open; the opposite direction of fluid flow by gravity, fluid pressure and valve closing effect on the valve seat, thereby cutting off flow.

We mainly produce various check valves (for example,single disc swing check valve,double disc swing check valve,ball check valve,lift check valve, butterfly valves,diaphragm valves ,ball valves and so on). Our products are widely used in municipal water and wastewater ,oil,chemical, food and other fields.Our entire valves are designed and manufactured according to ANSI (ASME), DIN, BS, JIS and other standard. Also, we ensure the best quality for customers, and our strict quality assurances systems are conducted throughout the entire production at the standard of ISO9001:2008 and CE.
