Q:What is the difference between gate valve and gate valve? Is it the same valve?: The valve is driven by the valve stem to make vertical lifting of the plate inside the valve body.Gate valve is the same reason. The gate valve and gate valve have steel gate, parallel double gate and so on.So the gate valve and gate valve are the same valve. It's just a different name.

Q:What do you mean by "2" and "200 CF8M"?: CF8M is 316,2 "is 50200 caliber stainless steel pressure (American Standard, LB)

Q:What's the meaning of the gate valve model z41x 16Q?: Gate valve (Z) flange connection (4) wedge type single gate (1) rubber soft seal (X) -16 pressure) (Q)

Q:What do you mean by gate valve type RVHX-0150-10 and Z45X-16Q?: Z45x-16q, Z means gate valve, 4 means flange connection, 5 refers to dark rod gate valve, X means rubber seal, 16 refers to nominal pressure 1.6MpaRVHX means manual gate valve, 150 refers to the caliber of DN150, and 10 indicates nominal pressure of 1.0MPa

Q:What does gate z41t-10 150 mean?: According to JB/T308-2004 "valve type programming method"Z gate valve4 flange connection1 Ming wedge single gateT sealing cover material is copper alloy10 nominal pressure PN10PN16 below no marked valve body code, body material is gray cast iron150 nominal size DN150

Q:What is a protective gate valve? What is gate valve knowledge?: Explosion-proof valve products, is a kind of safety valve can eliminate the shock wave which can stop the water hammer shock wave, it is a product composed of multiple sets of safety,

Q:Internal screw current limiting gate valve (Tan Gang) PN5.0 DN15/ Phi 1 Rc1/2 what does that mean?: We did thatInternal thread current limiting gate valve (Tan Gang)Body material: carbon steelPressure rating: PN5.0 = 300LB American StandardNominal = DN15 = 1/2"Phi 1 = in the middle of the gate drilling a Phi 1 hole, so that in closing there will be a certain flow, that is, the minimum flow, that is, the current limit.Rc1/2 is thread, which is the connection

Q:What kind of valve is gate valve? Is it different from the cut-off valve?: Gate valve and the role of the cut-off valve, are playing a role in isolation. The difference is that the gate valve and the cut-off valve are constructed differently. Fluid from the gate valve flow and flow direction is straight, there is no change in direction, but in the cut-off valve is from the bottom of the valve flow into the flow from the upper part of the spool.

Q:What does gate valve Z44T-10-200 code mean?: The meaning of the model is standard, the landlord himself to check the JB/T308 standard, Baidu library some, and is free to download:JB/T 308-2004 valve type method of preparation clear EditionHttp://wenku.baidu.com/view/5f798850ad02de80d4d84036.htmlZ = gate valve4 = connection: flange4 = structure form: double gateT = sealing surface material: Copper10 = nominal pressure: 1.0MPa, followed by no letters indicate body material: Cast Iron200 = nominal path: DN200

Q:Function of gate valve: Valve strengths: (1) fluid resistance is small, due to the valve inside the valve channel is straight, and the medium flow through the valve does not change its direction of movement, so the fluid resistance is small. (2) the opening and closing moment is small, opening and closing more effort, as the gate valve opening and closing, the direction of movement of the gate and the direction of the media movement vertical, compared with the cut-off valve, valve opening and closing more effort. (3) the direction of the movement of the media is not limited, no disturbance, no pressure reduction, the media can flow in any direction from both sides of the gate valve, and all can achieve the purpose of use, more suitable for the direction of the movement of the medium may change in the pipeline. (4) the length of the structure is relatively short, because the gate of the gate valve is vertical inside the valve body, and the stop valve clack is horizontally placed in the valve body, so the length of the valve is shorter than the cut-off valve. (5) the sealing function is good, when the full opening, the sealing surface is less eroded. (6) when fully open, the sealing surface is less eroded by the working medium than the cut-off valve. (7) the shape is relatively simple, the forging technology is good, and the scope of application is wide.
