Water depth: 5 meters in normal, specify in ordering when special requirements needed.

Suitable temperature: -20 degree ~ 85 degree

Suitable medium: Sewage, clean water, sea water, etc.

The maximum leakage volume: 1.5L/M/H(M is length of sealing surface, hour is time)

The maxium manual open and close power: up to 350N(not including 350N)

Operation mode: Manual,electric operated,pneumatic operated

Design and manufacture standard: AISC,AWSD1.1-88,SL74-95,DL/T5018-94

Gate is one of the most common open/close, use of ram (namely the open-close part, in the gate opening and closing a called ram or gate, gate called ram block) to connect (full open) or truncation (seated) line in the medium.It does not allow for river closure, use should be avoided in the open gate trace, because of the erosion of high-speed flow of medium will accelerate the damage of the sealing surface.Double DE gate at the channel center line perpendicular to the gate of the one-sided as lifting movement, like gate cutting medium pipeline, so as the gate valve.

Q: What are the specifications of the gate valves? Does the work pressure need to be marked separately?: Gate valve code Z, such as GB gate valve Z41H-16. Front is the valve type, and the back 16 represents the pressure of 16 kg, 1.6MPa

Q: Z45T-10 what kind of material is the gate valve?: Cast iron, sealed with copper alloy inside. Shanghai Yu Cheng fluid on the professional production of this thing,

Q: Analysis of the advantages of elastic seat sealing gate valve?: When the elastic seat sealing gate valve is closed, the sealing surface can be sealed only by the medium pressure, that is, the sealing surface of the flashboard is pressed to the valve seat of the other side only by the medium pressure to ensure the sealing of the sealing surface, which is self sealing.

Q: How to distinguish between gate valve and cut-off valve?: Two can be closed, in the flow of linear requirements are not high, you can adjust the flow. Just because of its structural characteristics of the valve to make its flow resistance, so there is a demand for throttling with a little more than the gate valve. In addition, the cut-off valve, whether it is a formal or reverse installed, in the opening and closing process, there is always a very difficult, and therefore can not do a great deal, or it is not easy to open and close. In addition, the cut-off valve has a one-way sealing effect of good features, so in the prevention of reverse flow of the working fluid, it also has a place to play.Hope to be of some help to you!

Q: Why? God, can you explain to me in detail why?: Pump outlet, check valve, gate valve.Gate valve plays a regulatory role, is the main pipe. Such a sequence can ensure that the water flow during power failure does not cause damage to the gate valve.

Q: Is the gate valve clockwise or closed?: In general, the valve is clockwise to turn off. Some of the clockwise rotation of the valve on the move is open

Q: What do gates, Z15T-10, Z15W-16T, Z45T/W-10, Z41T-10 mean?: 7-, dark bar parallel gate valve, parallel gate valve 9- dark bar;5, sealing materials or lining materials were used R- T- austenitic stainless steel, copper alloy, X- rubber, S- plastic, N- nylon, F- fluorine plastic, H-Cr series stainless steel, hard alloy Y-, J- rubber, M- Monel alloy, Tc- ceramics;6, the body material code Z- K- gray cast iron, malleable cast iron, Q- ductile iron, copper and T- alloy, C- steel, P- chromium nickel stainless steel, R- stainless steel chromium nickel molybdenum, chromium molybdenum vanadium steel V-.For example: for electric, flange connections, Ming Liang wedge double gate, the sealing surface material directly processed by the body, nominal pressure PN0.1MPa body material for gray cast iron gate valve: Z942W-1 electric wedge double gate valve

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: Gate valve is gate valve, gate valve specifications, model code is generally what?: Gate valve is not gate valve, gate valve does not have a fixed specific model

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
