Q: What causes the stem to be stuck?: 1. is the pressure plate, the root screw is too tight, you can loosen the screw, you can add a lubricant in the packing and stem connection.2. may be too tight packing, but there may be stem rust.Of course, the most important question is what you operate is the valve? Different types of valves are available for various reasons.

Q: Is the strength of the ball valve stem and torque the same?: No, that's the two concept. In the specification, the pressure rating unchanged, including the influence factors of the medium pressure, torque, temperature, medium viscosity and so on. So the torque change. Change the stem strength structural parameters, and the change of temperature change. But the stem strength must be greater than the valve torque.

Q: What's the difference between the stem and the pole?: Valve stem is iron rod, hardness is very high, the overall length is not long, is not conducive to throwing, mainly for bait, let the bait automatically fall to the designated depth for search. The pole is mainly used for throwing, relatively lighter, elastic, and the length is very long.

Q: Where is excavator, multiway valve stem processing?: Unfortunately, scanty domestic manufacturers are manufacturing excavator multi way valve stem, a little known is Nakagawa hydraulic.

Q: Can the valve stem be lengthened?: Make a longer valve wrench, so it is much easier to switch the valve.

Q: When the butterfly valve is installed, can the stem be downward? What are the criteria?: According to the direction of the pipeline and easy to operate.

Q: Can the stem fish where there is grass?: The stem is mainly short pole (regular 1-2 meters), mainly in the river, river reservoir and other large water area boat fishing.

Q: What is the cause of valve stem vibration in electric single seat control valves?: 3, liquid medium through the valve, resulting in cavitation caused by shocks, higher frequency, usually accompanied by valve howling. High temperature large pressure difference, the use of single seat valve is relatively easy to happen, this is the control valve (valve body structure) type selection caused by improper,4, the valve core resonant frequency and pipe and fluid frequency consistent with the vibration caused by higher frequency, usually accompanied by pipe vibration. Change the valve at both ends of the process, valve opening may be eliminated.

Q: Natural gas, oil or steam suitable for valves, valve stem, respectively, what is the material?: See medium type, acid or alkaline, corrosion resistance, suitable for natural gas, oil or steam applicable valves, many kinds of ah, 2Cr13 304, 316, and so on,

Q: Shandong 30 loader multiple valve stem card what's wrong.: You take the two main stem carefully removed, check the stem and valve bore cavity whether there is scratch, if there is a local scratch, it may be dirty stuck in it, and then pull the stem when it pulled. Scratches if deep, leakage will be large, repair will feel bucket slow, little force and so on. All components should be removed before washing, especially the safety valve. After the demolition, the whole body with kerosene cleaning, safety valve pressure should not be adjusted, or there is no test stand, you do not know the specific pressure is how big.
