Q:Are there any problems with the horizontal installation of the pneumatic butterfly valve on the horizontal pipe? Is it serious?: Especially the butterfly valve pneumatic valve is generally installed vertically, horizontally mounted, the stem sealing effect of internal gravity packing layer, resulting in loose packing, the risk of leakage, and the pneumatic valve of the valve positioner will reduce the accuracy of adjusting clearance, cause.In addition, the butterfly valve sealing surface may also be deformed because of the stem deformation and wear.This is the danger, not necessarily be a problem, but the large-diameter valves such as DN150 or more dangerous, if you have a small caliber valve (butterfly valves are generally large, with a small caliber ball valve), will do some suggestions, safety, adjust the installation position.This answer is adopted by the questioner

Q:Shandong 30 loader multiple valve stem card what's wrong.: 2., if the cylinder problem, the stem or valve hole will appear on a continuous block where there are grinding marks, the stem groove is a lot of fine iron powder, this situation can be responded to manufacturers, request a good change.In fact, many problems are cleanliness problems, and if you know how to wash, that is not a waste of time, simple and effective.

Q:Stem material: 5, bearing steelSelection of GCr15, applicable to the nominal pressure is less than 300MPa, the temperature is less than or equal to 300 degrees of ultra-high pressure valve.Used to make the stem more materials, as well as 4Cr10Si2Mo martensitic heat-resistant steel, 4Cr14Ni14W2Mo austenitic heat-resistant steel.The stem nut and the valve stem match with the screw thread, and directly bear the axial force of the valve stem, and the friction between the plate and the support valve. Therefore, the stem nut in addition to a certain strength, but also requires a small friction coefficient, not rust, and stem does not bite and other performance.

Q:Liquefied petroleum gas cylinder angle valve stem leak how to do?: The angle valves manufactured in batches must be certified and approved by the manufacturer, the competent department and the local labor department.
