Q:GB 300 gate valve, a multi?
GB DN300 flanged gate valve, PN10 manual 245kg bevel gear 315Other pressure levels, please specify specific pressure.Wenzhou Chaoda group Agel Ecommerce Ltd to provide the answer:
Q:Gate valve is gate valve, gate valve specifications, model code is generally what?
Valve lock plate valve, gate valve and code.According to domestic valve model standards, the valve model is by the valve type, gate valve drive mode, gate valve connection, gate valve structure, sealing material, valve body material code to indicate.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 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: electric, flanged, rod wedge gate valve, sealing surface material by direct processing, nominal pressure PN0.1MPa of the valve body is made of grey cast iron gate valve: Z942W-1 electric wedge gate valve.
Q:Why is gate valve or butterfly valve used for water pump?
General pressure is small, use the butterfly valve, when the pressure is big, use the gate valve. The two main function of the valve is to adjust the flow and easy to overhaul.Zibo Boshan new Duke water supply equipment
Q:What do gates, Z15T-10, Z15W-16T, Z45T/W-10, Z41T-10 mean?
Z15T stands for manual, internal thread connection, dark wedge single gate. The sealing surface is made of copper alloy. The nominal pressure is PN1MPa;Z15W-16T for manual, internal thread connection, dark wedge type single gate, the valve body material is copper alloy, the valve seat sealing surface material directly processed by the valve body, nominal pressure is PN1.6MPa;Z45T/W-10 stands for manual, flange connection, dark wedge single gate. The valve body is made of copper alloy, and the valve seat face material is directly machined by the valve body. The nominal pressure is PN1MPa;Z41T-10 stands for manual, flange connections, plain wedge single gate, sealing surface material is copper alloy, nominal pressure is PN1MPa.According to domestic valve model standards, the valve model is by the valve type, gate valve drive mode, gate valve connection, gate valve structure, sealing material, valve body material code to indicate
Q:What's the difference between open rod gate and dark rod gate valve?
3, dark rod valve is located inside of the body, in the process of opening and closing, stem only rotation move, the gate in the valve body lifting; the valve stem rod driven gate valve with the valve stem of the lifting drive thread in the external body, according to the direction of movement of the stem and the position of judge the gate opening and closing and position;
Q:About fire valve is gate valve or butterfly valve problems?
Disease is generally in accordance with the design requirements, regardless of the butterfly or tie hair to meet the requirements, are two-way valve.
Q:Gate valve type Z40Y, Z40H letters - what does that mean?
According to the provisions of the JB/T 308-2004 valve type programming method:Z== gate valve4== connection: flange0== structure: wedge type elastic RAMY== sealing surface material: hard alloyH== sealing surface material: Cr13 stainless steel
Q:What does gate valve do?
Valve in the pipeline can only be fully open and fully closed off, can not be adjusted and the throttle. Gate valve is a valve used in a wide range, generally more than 50mm caliber DN block device is selected it, sometimes cut off very small aperture devices are used to gate valve, gate valve is used as cut-off media, when in full flow through the whole, when the media is running a minimal pressure loss. Gate valves are normally used in situations where they do not need to be frequently opened and closed, and the gate is fully open or fully closed. Not used as an adjustment or throttling. For high speed moving medium, the gate can cause the vibration of the gate under the condition of partial opening, and the vibration may damage the sealing surface of the gate and the valve seat, while throttling will cause the gate to suffer the erosion of medium.
Q:What is the standard for ductile iron gate valve set?
The valve material name, specifications and price according to the facts that the valve rod input line.
Q: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,
