Q:What's the meaning of the double ball valve in the double ball valve?

By means of "union", the "live" means that the two ends of the valve are connected by a live joint

Q:That is to say, there is still a difference The man in the workshop said it was one thing... It's completely confusedHere are the data for the two valves. Please consult with the experts.Ball plug valve, high temperature cast steel, A216Gr.WCB flange, two pass, full quantity type 3, X 150LB RF ball / rod, 13%Cr seat, PTFE handle openBall valve Q41F-150LB-3"

Ball, ball, hole, rotary ball, control, closureBall valve and plug valve is almost straight round solid ball.

Q:Stainless steel ball valve Q41F-16P DN80 weight is

The whole diameter is about 40kg heavyThere is a slight difference between the manufacturers

Q:Pneumatic two stage ball valve principle

By two pneumatic actuators and ball valve or butterfly valve, the piston stroke change additional cylinder, actuator and valve angle is stopped at a predetermined angle (45 degrees -90), so the valve flow can be adjusted. This device by two solenoid valve control valve flow. As the actuator uses the rapid exhaust and throttling function, so that the two segment ball valve has excellent switching characteristics. Slow open and close valve velocity, the fluid in the pipeline to change smoothly, not because of the impact of water hammer in the flammable fluid explosion, nor system flowmeter and other instruments damaged by the impact of the flow, it is suitable for the industries of petroleum, chemical industry, light industry, national defense and other control systems, especially suitable for oil storage and transportation system.

Q:What does "F" and "C" mean in the Q11F-16C of the ball valve?

This model is not international standard number, but still can see, of which, F refers to the sealing material: fluorine plastic, C refers to the body material: carbon steel.

Q:What does "ball pq340h-10c-1200" mean?

This is the worm gear eccentric hard seal hemisphere valve, 10 kilograms of pressure, caliber is 1200.

Q:For our valve beginners, how intuitive decision is floating ball valve or fixed ball valve?

Floating ball valves and fixed ball valves can be located in the lower stem position, if there is a lower stem is fixed ball valve

Q:DN20 copper ball valve with large PPR converter connector

What do you see a ball valve, PPR ball valve, ball valve with internal screw threads, ball valves, but if you look at the butt of the ball size, if the ball is 20. The tube is 20, then the 20*1/2 internal thread can be directly on the butt.

Q:Ball valve, PTFE pad inappropriate choice, is not easy to bad ah?

Yes, but not in a high temperature for a long time, like more than 180 degrees centigrade. Because the gasket can not be used after deformation, it will cause valve leakage.

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.
