FAQ

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.
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.
What's the difference between a soft seal gate valve and a hard sealed gate valve?
It uses the elastic material of the gate, and uses the elastic material to produce the micro deformation compensation effect. It can achieve good sealing effect. Soft sealing gate valve has the advantages of light switch, reliable sealing, good elasticity memory and long service life.Hard sealing surface of the gate valve for cast iron or stainless steel, open and close resistance is small, no flow, but poor sealing performance.
The difference between flanged gate valve and common gate valve
Flange valve: English name; Flange Gate Valve is the gate opening and closing parts, RAM direction of motion perpendicular to the direction of the fluid, valve can only be fully open and fully closed, can not be adjusted and the throttle. Gate has two sealing surface, the most commonly used mode gate valve of the two sealing surface to form a wedge, wedge angle with valve parameters vary, usually 50, medium temperature is not high when 2 degrees 52'. Wedge gate valve can be made into a whole, called the rigid gate; can also be made to produce micro deformation of ram, in order to improve its process of deviation, make up the sealing surface angle in the process, the gate is called the flexible gate.Ordinary gate valve: mainly used to connect or cut off the medium in the pipeline, not applicable to regulating medium flow. Gate valve applies to pressure, temperature and caliber range is great, especially for medium, large diameter pipesThe most important difference: flange gate valve and ordinary gate valve is different, flange gate valve quality, durable, easy to install, but higher prices, generally used for large pipelines. Ordinary gate valves are used for small caliber, easy to change places.
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
What does "Z45W-10T" mean?What does each letter stand for?
For type PN10 Z45W Brass Gate ValvesZ is the valve type code, which represents the gate valve;Driving mode is hand wheel (code name omitted);4 is the connection form code, which represents the flange;5 is the gate valve structure form code, represents for the dark pole wedge rigid single gate;
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
Analysis of the advantages of elastic seat sealing gate valve?
General valve on the market for a long time there is Water Leakage or rusting, overcome the valve seal bad, rust and other defects, using the elastic elastic valve seat seal gate produce small quantities of elastic deformation of the compensation function to achieve a good sealing effect, with a switch to lighter and reliable sealing, good elastic memory and life and other significant advantages. The utility model can be widely used as an adjusting and intercepting device for pipelines such as water supply, sewage, building, petroleum, chemical industry, food, medicine, light industry, electric power, ship, metallurgy, energy system, etc.. This is the advantage and advantage of an elastic seat seal gate valve.
