WCB Gate Valve DIN3352 1. Factory pice 2. Short Delivery Time 3. All size
BS5136/5150 Ductile Iron Gate Valve
Main technical parameters
The main characteristics and uses
1. Compact structure, rational design of rigid valve, and channel flow, flow resistance coefficient. 2. Sealing surface using stainless steel and cemented, long service life. 3. The use of flexible graphite packing, sealing reliable, flexible and lightweight. 4. Drive sub-manual, electric, pneumatic, gear transmission, structure type: a flexible wedge gate single rigid wedge and the single-gate modeldouble plate board. 5. Widely used in petrochemical industry, coal-fired power plants such as oil, water, steam pipe on the road for access or cut-off line in the gate dielectric

Q:Fire protection gate valve from the wall how many distance there is no regulation?
1 meters away from the wall, leaving the maintenance and replacement distance
Q:What does Z941H-25DN250 mean by electric gate valve (excluding electric equipment)?
sealing surface configuration can be divided into wedge gate valve and parallel gate valve, wedge gate type valve can be divided into: single gate type, dual gate plate and the flexible gate type; parallel gate valve can be divided into single and dual gate gate plate.
Q:What is the difference between gate valve and gate valve? Is it the same valve?
Gate valve and gate valve are 2 kinds of valves, do not feel like a long name is the same kind, please look at Baidu maps introduced manufacturers.
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:What are the specifications of the gate valves? Does the work pressure need to be marked separately?
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,
Q:What kind of copper gate valve copper content standards, there are no national standards?
Please refer to: GB/T12225-2005 "general purpose valve, copper alloy casting technical specification" and GB/T 15116-1994 "die casting copper alloy"
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 valve is z45w gate valve?
Cast iron gate valve with turbine head, please contact me
Q:What is the size and length of the DN80 gate valve? 10 kg and 16 kg, respectively?
Valve structure length standards are PN16, short series for 203mm, long series for 280mm, flange size by PN16.
