FAQ

What's the meaning of flexible z45x-10q door valve?

Crown valve pressModel Z45X-10QZ refers to gate valve4 finger flange connection5 refers to the dark bar driveX refers to rubber seals10 refers to 10 kg pressureQ refers to the body material, ductile ironFull bore flange soft sealed gate valve

What is the difference between gate valve Z41T and Z45T?

Z41T is a dark pole gate valve, and Z45T is a plain rod gate valve,

What is an inverted seal gate valve?

When the inverted sealing gate valve is fully opened, the sealing of the sealing is brought together, and the sealing effect is reduced, and the erosion of the filling to the fluid is reduced, and the service life of the filler is prolonged, and the possibility of leakage is reduced. Generally on the gate valve, stop valve has inverted sealing requirements.

Gate valve z45h-10dn250 length of the body?

Z45h-10dn250 body length L=330mm, this valve is hidden bar, elastic seat, sealing gate valve, gate lining, lining fluorine, belong to soft seal

What does Z941H-25DN250 mean by electric gate valve (excluding electric equipment)?

9- electric (drive)4- flange connection (connection)1- plain wedge single gate valve (valve structure)H-Cr stainless steel (sealing surface material)25- nominal pressure is 25 kg, or 2.5MPa;DN250- valve by 250mm

What do you mean by "2" and "200 CF8M"?

CF8M is stainless steel, and 2 is caliber 50200 and should also be bore

Analysis of the advantages of elastic seat sealing gate valve?

Most of the valve is forced seal, that is, when the valve closed, to rely on external force to force the gate to the seat, in order to ensure the sealing surface sealing.When opening the gate valve, when the gate lift height is equal to 1:1 times of the gate diameter, the passage of the fluid is completely unblocked, but at run time, this position is unable to monitor. In actual use, the top of the stem is used as a sign, i.e., the open position, as its fully open position. Temperature changes appear to consider locking phenomenon, usually open to the vertex position, and then rewind 1/2-1 circle, as a fully open valve position. Therefore, the opening position of the gate valve is determined by the position of the gate (i.e. the stroke). The sealing surface is easy to wear and tear, affecting the service life. When opening and closing, gate and valve seat two sealing surface friction, sliding, to medium pressure under the action of easy to produce abrasions, wear, affect sealing performance, shorten service life.

What's the difference between the knife gate valve and the stop valve?

Standard light valve professionals to answer for you, gate valve refers to the closure of parts (gate) along the central line of the vertical direction of moving valve. The gate valve is mainly used for cutting in the pipeline. The valve is a valve with a very wide, cutting device general caliber DN = 50mm use it, sometimes a small diameter cutting device also use valve, gate valve has the following advantages:Fluid resistance is small.
