- Q: What are the differences between the pneumatic ball valve and the pneumatic angle seat valve?
- Characteristics of pneumatic ball valve:1. Rotate the spool to make the valve clear or closed.2 pneumatic valve switch light, small size,3. It can be made into big caliber,4 、 reliable sealing, simple structure, convenient maintenance,5, sealing surface and spherical surface often in closed state, it is not easy to be medium erosion.
- Q: What is the difference between floating and fixed ball valves?
- Ball valve according to whether the ball is supported, can be divided into spheres, floating and fixed type of two.
- Q: What does "S" mean by ball valve Q11S?
- S is the body material code, plastic.
- Q: Open the pressure relief valve core hole with what
- Attention to maintenance methods of eccentric hemisphere valve:1, eccentric hemisphere valve in the closed state, there is still pressure fluid inside the valve body.2 、 before repair, release the line pressure and make the valve in the open position.3. New parts should be cleaned before assembly.4. Remove the actuating mechanism from the support before servicing.5, non-metallic parts cleaning should be immediately removed from the cleaning agent, not long immersion.6, need to be cleaned by washing the wall after volatile cleaning agent (cleaning agent can not dip silk rub) for assembly, but not for a long time on hold, otherwise it will rust, dust pollution.
- Q: What does copper ball valve type Q11F-16T mean?
- Q11F-16T, Q refers to the ball valve, 1 refers to the connection mode, the latter 1 refers to the straight through type, F refers to the sealing material, 16 refers to nominal pressure, T refers to the main material for copper material
- Q: Ball valve 11F, 41F, 11H, 41H
- 41H flanged ball valve type through the use of alloy steel seal. In addition there is a complete expression of Q words, there are nominal pressure such as Q11F-16 Q41F-16
- Q: What's the difference between a ball valve and a butterfly valve? Which one has better sealing performance?
- (1) the butterfly valve from the valve body, valve seat, valve plate, valve rod, all parts are a significant drain on the outside, one eye can see; the ball valve is composed of a valve body, the valve core (a round ball), valve rod, valve position is in the valve body inside, the naked eye can see only a part, so the seal the performance of the valve than the butterfly valve well;
- Q: What does "ball Q41F-16" mean?
- Q- ball, 4- flange connection, 1- DC channel, floating ball, F- sealing material for fluorine plastic, 16- nominal pressure of 16 kg, the valve body material for gray cast iron. If you want to know the details of the valve named model establishment, can refer to the JBT-308-2004 standard.
- Q: Ball valve Q41f and Q11f difference, whether universal?
- Q41 is flanged ball valve, Q11 is a threaded ball valve, the two connections in different forms, is not universal.
- Q: Our factory has part of the ball valve in the direction of movement and normal ball valve is the opposite direction: anti clockwise for the turn off, clockwise. Excuse me, what's the reason for this?Excuse me, is this because the valve body installs the reason of the contrary or the reason, the ball valve is thus designed?Are there any positive and negative points when the ball valve is installed?
- Ball valve is 90 degrees switch, you may put the handle of the wrong position, change 90 degrees, try it
