Q:What is the reason that the valve stem can not be rotated in the water supply pipe?: Crown valve pressIs it stuck? You can't drive it?Or handwheel, stem does not turn?Shut off for too long too much death will not open in the first.

Q:How to judge the quality of fishing stem?!: The regular brand fishing line, mellow, soft texture, good surface smoothness, high strength, good wear resistance nodules. At present, the market of various brands of fishing, whether mixed together.

Q:How to adjust the valve stem valve leakage?: The valve leakage is 1, the spool and the valve seat sealing surface wear, grinding or replacement; 2, 3, the stem is too short; there is a foreign body card in

Q:What are their respective advantages and disadvantages?: Valve advantages:1, small flow resistance. Inside the valve body, the medium passage is straight through, the medium flows in a straight line, and the flow resistance is small.2, when opening and closing more effort. In comparison with the cut-off valve, the gate movement direction is perpendicular to the direction of the flow of the medium whether it is open or closed.3, high height, long opening and closing time. The opening and closing stroke of the ram is larger, and the reduction is done by screw.4, the media can flow in any direction on both sides, easy to install. Gate valves are symmetrical on both sides of the channel.5. Compact structure, good rigidity of valve, smooth channel, small flow resistance, stainless steel and carbide alloy used in sealing surface, long service life, PTFE packing, reliable sealing, easy and flexible operation

Q:What about the water leakage at the valve stem of the sanitary manual stainless steel butterfly valve?: The following can be done:1, small diameter, you can buy a new, you can replace the spool;2, the big diameter can be purchased by the corresponding specifications of the sealing ring replacement.

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:How is the hand (knob) of the hand operated ball valve connected to the valve stem?: Normally, there is no such thing. Because it is easy to rust for a long time.Do not use valve repair (can not be removed)

Q:What does the stem material VTA mean?: Valve stem: the valve stem is not only moving parts, force components, but also seals when the valve is opened and closed.

Q:I heard that there is a special production valve stem equipment, automation, production accuracy and production efficiency are high equipment: It can be done with an ordinary lathe, and other machine tools do not provide much speed

Q:How does the positioner output change when the feedback lever of the positioner and valve stem falls off?: The positioner and the control valve are connected with the feedback rod to fall off, and the positioner has no feedback and becomes a pneumatic amplifier with high magnification. If the positioner is positive, that is, the signal increases, the output also increases, then the stem fell off, the output run the maximum, and if it is counterproductive, then run zero.
