Q:Gate valve z41t what does that mean?

According to the provisions of the JB/T 308-2004 valve type programming method:Z = gate valve4 = connection form: flangeT = sealing surface material: copper alloy

Q:What do gates, Z15T-10, Z15W-16T, Z45T/W-10, Z41T-10 mean?

1, gate valve type code named Z;2, gate valve drive mode code by letters, common 2- electric hydraulic, 9- electric, 6- pneumatic, 5- bevel gear drive, 3- turbo worm; manual do not need to write out;3, gate valve connection form code with letters to indicate, 1- internal thread, 2- external thread, 4- flange type, 6- welding, 7- pairs clamp type, 9- clamp, 0- card sleeve;4, the valve structure of code, 0- flexible wedge, 1- rod single wedge gate valve, 2- rising stem wedge gate valve, 3- parallel single gate valve, 4- parallel double gate valve, 5- dark pole single wedge gate valve, 6- dark bar wedge gate valve

Q:What gate valve is the J41H-150LBDN100 gate valve?

Its closing principle is to rely on the valve bar pressure, so that the valve sealing surface and seat sealing surface close together, to prevent the circulation of media. The cut-off valve is divided into three kinds: straight through type, right angle type and direct current type oblique stop valve.

Q:What is an inverted seal gate valve?

It refers to the middle part of the valve sealing valve valve sealing surface, the valve cover has a sealing seat, which is the valve and stem as well as the joint of the valve rod and the valve cover (i.e. internal stuffing box at the bottom of a sealing structure).

Q:What is gate valve (with force transfer joint)?

The force transfer joint is mainly used for the loose connection of pumps, valves and other accessories.

Q:What is the difference between a flanged gate valve and a wire gate valve?

Flanged gate valves are flanged and must be welded to the flanges of the pipe, bolted together

Q:Notes on flat gate valves

internal structureThe 1 seat O ring seal and preload floating seat structure, so that import and export of two-way valve seal plate; and the structure of the normal valve opening and closing torque only 1/2, can easily open and close valves2. when fully open, the channel is smooth and straight, the flow resistance coefficient is extremely small, and there is no pressure loss. The pipeline can be cleaned through the hair bulb3 the packing structure with the ability of self sealing, without frequent adjustment, opening and closing very lightweight, and reliable seal, the stuffing box is arranged at the auxiliary seal oil into the structure, absolutely reliable sealing performance, thereby achieving zero leakage; solve the shortcomings of the general valve packing leakage of the most vulnerable4., when the flat gate valve is closed, it can automatically unload the inner cavity high pressure, and ensure the safe use5., fully enclosed structure, good protection performance, can adapt to all-weather requirements6., the valve seat sealing structure should be elastic, preload, upper and lower sealing seat at the same time sealed structure. The valve seat and the seal are always face to face sealed.The 7. seat has self-cleaning function and is free of direct airflow during valve opening or closing. The seat shall be made of lubricated, non wearing material.8. valve actuator failure will not affect the other parts of the valve, maintenance and replacement work can be carried out without removing the valve.9. yoke sleeve aluminum bronze yoke sleeve with pin type thrust bearing to minimize operation torque.10. stem - thread length until bracket; dowel and spot welding; stability.11. pressure seal - simple construction, with sectional retaining rings and silver plated low carbon steel gaskets, helps to remove and achieve the best bonnet seal.12. seat ring - welded seat ring is perpendicular to the flow channel and is easy to maintain.

Q:What do you mean by forged steel gate valves 800LB DN20 SW?

Is the forged steel gate 800LB is DN20 on SW welding pressure

Q:What does "Z45W-10T" mean?What does each letter stand for?

W is the seal material or lining material code, the valve sealing material is the valve body material, the valve sealing surface material code with "W" said, here stands for brass;The 10 is the pressure code, which stands for PN10, which is often called 1.0MPa;

Q:Why can't the pressure measuring point be set at the two ends of the gate valve when measuring the resistance loss of the gate valve?

the valve before the pressure measuring point, distance of valve straight pipe length is 5 times the diameter of the valve after the pressure valve, the distance is 10 times the diameter of straight pipe length.
