Q: How to use a dial indicator measuring stem bending: 1) when measuring, both ends of the journal are supported on the ball bearing, and the thrust of the shaft should be limited to 0.10mm within the range of measurement.(2) the equal axis along the length direction measurement, measurement point selection in the surface must be free of burrs, pitting, bulge, smooth pit shaft.

Q: What exactly is the stem nut, please: The stem nut has a certain strength and resistance to pressure, because the stem nut is the valve running process, the stem shaft strength directly to the stem nut. The stem nut and stem are rotated with the thread, and the friction coefficient of the stem nut is smaller.

Q: What is the valve stem and valve seat of the indoor fire hydrant?: The stem and the valve core are copper,The seats are cast-iron and ductile

Q: Beijing exhibition, understand that Hauck can equipment, our existing batch valve stem need to be handled, I wonder if their home equipment use effect?: and the service is also very timely, good service attitude, our company is planning to buy a.

Q: DN>=50 valve, stem and bracket between the use of lubricated bearings, and stem exposed part should be dust-proof measures to prevent atmospheric corrosion. TwentyDoes it mean that all DN>=50 valves, valves and supports must be lubricated with bearings, or that only the bearings are used between the valve stem and the bearings?: All need dust protection measures, long time, in order to prevent the garbage things adhesion

Q: Stem V type PTFE packing maximum pressure /?: At the same time, it is subjected to the impact and corrosion of the medium, and it also causes friction with the packing. Therefore, in selecting the stem material, it must be guaranteed that it has sufficient strength at the prescribed temperature, good impact toughness, scratch resistance, corrosion resistance.

Q: Pipeline ball valve in the valve stem generally choose what material?: Generally, there are the following choices: AISI 4140, A182, F6a, 17-4PH, A182, F316, A182 304, AISI 1040, ENP

Q: What are the meaning of the LH for the size of the valve stem of the electric gate valve?: The size of the valve stem of the electric valve is LH. The thread of the electric valve indicates that the thread is left.

Q: Stem deformation of valve stem: So why would the stem fracture or deformation of a few points: normal temperature and pressure of the valve body cavity there is closed, that is closed in the valve, the fluid pressure in the cavity closed at the upstream and downstream sides between the sealing surface is far higher than the upstream pressure.

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,
