Q:How to adjust the valve stem valve leakage?
4, in the valve seat; the actuator stiffness is too small; 5, the valve before and after the pressure is too large; 6, the valve positioner failure; 7, diaphragm or gas path pipeline leakage.
Q:What causes the stem to be stuck?
Many reasons, stem, valve shaft assembly size is not right, or packing with too tight can cause, stem finish is not enough, can produce
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:How about valve stem with 660?
If the action is not very frequent, the condition is not very complex, harsh, it should still be possible. Heat treatment will be better
Q:Is the strength of the ball valve stem and torque the same?
The question is not very clear, in the specifications, 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.

Q:Liquefied petroleum gas cylinder angle valve stem leak how to do?
Therefore. There is a leak of gas cylinders, is substandard products, are not allowed to leave the factory, not allowed to use. Users in exchange for new refillable liquefied petroleum gas cylinders, use soap bottle, bottle valve and cylinder weld joint, bottle valve outlet and stem, observed that the air bubble is leaking, this bottle is unqualified, shall be immediately returned to the station for bottles, filling station that is the replacement of a liquefied petroleum gas bottle, the replacement of qualified angle valve. Angle valves are important safety accessories for liquefied petroleum gas cylinders, and the Ministry of urban and rural construction, Ministry of environmental protection and Ministry of labor and personnel have promulgated standards.
Q:What is the material of valve stem F6A?
1, the ball valve F6A in the material belongs to forged low alloy or stainless steel alloy, this is the United States corresponding code.2, China this material corresponds to the model generally has two kinds, specific for 1CR13 and 2CR13.
Q:At the Beijing show, Hauck was able to understand the equipment
You said Shandong Huayun Hauck can do it, I just have one of their home equipment, is used to deal with the stem, my company is used before rolling, the effect is very good, there are lines, and later used their home equipment, the effect was not the same, very easy to mirror the effect of their home customer service;
Q:Can stem fishing snakehead? Do you have to use Lei Qiang to catch it? Ask for advice
This is not played, dare not assert! Downstairs continue! : handshake
