Product Description:

Gate Valve

 

Flange ends cast steel gate valve are used to cut or connect the pipe media under nominal pressure between class150-2500, working temperature≤600°C, in oil industry, chemical industry, fossil-field power plants.

Design Feature

1. Both design and manufacture are carry out strictly fellow API600 and API602. The products feature a reasonable structure, reliable seal, good performance and nice modeling.

2. Co hard alloy welded sealing surface, which is wearing resistance, erosion proof, abrasion proof and long-lived.

3. The surface and the adjusting media of the valve shaft are nitrogenized so that it is erosion and abrasion resistance.

4. Class≥900LB, the media cavity uses a self-tightening sealing structure to have the sealing performance reinforced along with the pressure rise so as to ensure the sealing performance.

5. There is backward sealing structure in the valve, so the sealing is reliable.

6. The material of the filling and the flange size can be chosen and the matched according to the applications and the requirement of the wier's. That can satisfy all kinds of working requirements.

Q:HVAC design, why is less than DN50 of pipe gate valve and cut-off valve,
It's not the valve! But the price relationship!
Q:What's the difference between the knife gate valve and the stop valve?
Minor force needed for opening and closing.Medium flow is unrestricted.When opening fully, the sealing surface is eroded by the working medium smaller than the cut-off valve.The shape is relatively simple and the casting process is better.The valve is used in the system is relatively large, to close the gate off system; and the valve is used in the system is relatively small, and to adjust the flow quantity of the system, can not be closed gate and globe valves of different specifications for many kinds of occasions, the valve rod valve the dark bar gate valve, wedge gate valve, single valve, multi valve valve body structure is different, large volume.
Q:What is the difference between cut-off valve and gate valve?
Simply put, the cut-off valve is one-way, only into, do not give up, the valve is two-way
Q:Function of signal butterfly valve and gate valve
The signal is the gate valve 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. Can be used to control air, water, steam, a variety of corrosive media, mud, oil, liquid metal and radioactive media and other types of fluid flow. 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. Signal gate valve is usually horizontal installation.
Q:The difference between flanged gate valve and common gate valve
Flange gate valve and ordinary gate valve difference is that the flange gate valve of good quality, durable and easy to install, but the price is a little high, generally used for large pipelines. Common, also available, such as small caliber, easy to change places.
Q:What type of flange does it fit with the gate valve?
According to the welding plate flange, flange material selection of piping material.
Q:What are the structural differences between parallel and wedge valves?
The structure of globe valve and gate valve. What does this article introduce first?What is parallel gate valve?The sealing cover is parallel to the vertical center line, so the sealing surfaces of the valve body and the gate are parallel to each other. This gate valve is the most common double gate plate, in order to shut down, so that the valve and gate two sealing surface contact closely asked, often used in two ram double sided thrust wedge block. Thus, when the valve is closed, the double side thrust block is contacted with the bottom of the valve body and is gradually stressed.
Q:What is the standard for ductile iron gate valve set?
Clear shot valve installation, is still under way of connection and specifications set "water supply and drainage, heating, gas engineering" or "industrial engineering" pipeline register quota corresponding specifications and installation methods of connecting the valve installed valve section.
Q:What does "Z45W-10T" mean?What does each letter stand for?
W is the seal material or lining material code, the valve sealing material is the valve body material, the valve sealing surface material code with "W" said, here stands for brass;The 10 is the pressure code, which stands for PN10, which is often called 1.0MPa;
Q:Is the gate valve flanged?
The most commonly used gate valves are threaded connections, flanged connections, and welded connections.Like the outer thread connection, the clamp connection, the card sleeve is seldom used.
We focuses on supplying special valves applied to long-distance pipelines, petroluem, petrochemical processing devices and other harsh working conditions.We offer integrated solutions for industrial valves.The leading products of group are ball valve series, control valve series, cryogenic valve series, high temp.& pressure valve series, special material and process valves series.
