The valve body casting of flange ball valves is made using silica sol, featuring a high-platform design that eliminates the need for supports, preventing torque errors and ensuring reliable opening and closing. The ball has high machining precision and is solid, minimizing material residue during flow and avoiding contamination.
Parameter level
1. Nominal pressure or pressure class: 1.0MPa-10.0MPa;
2. Nominal diameter or bore size: DN15 to 300;
3. Applicable temperature range: -20°C to 400°C;
4. Drive methods: manual, worm gear transmission, pneumatic, electric;
5. Valve body materials: WCB, CF8 (304), CF3 (304L), CF8M (316), CF3M (316L), Ti. Other materials such as duplex steel and ceramics can be selected for different applications, including water, steam, oil products, nitric acid, acetic acid, and oxidizing media;
6. Optional accessories: solenoid valve, limit switch, positioner, filter-reducing valve, clutch;
Features
1. The fluid resistance is small, and its resistance coefficient is equal to that of a pipe segment of the same length;
2. Simple structure, compact size, and lightweight;
3. Tight and reliable, the sealing surface materials of ball valves are widely made of plastic, offering excellent sealing performance,
It has also been widely used in vacuum systems;
4. Easy to operate with rapid opening and closing, requiring only a 90° rotation from fully open to fully closed, facilitating long-distance control;
5. Easy maintenance: The pneumatic ball valve has a simple structure, with the sealing ring generally being movable, making disassembly and replacement relatively convenient;
6. When fully open or closed, the sealing surfaces of the ball and seat are isolated from the medium, preventing erosion of the valve sealing surfaces during medium flow;
7. Wide applicability, with diameters ranging from a few millimeters to several meters, suitable for use from high vacuum to high pressure;
competitive advantage
1. The casting has passed the German TUV certification, featuring silica sol precision casting with a fine and aesthetically pleasing surface
2. Fire and static protection, compliant with API 607/6FA standards
3. Standardly equipped with Daikin M111 seal, with balanced factory torque
4. Unique valve seat spring design for smoother switching
5. Submerged cover design with adjustable compression for the packing section
6. V-shaped packing design ensures sealing performance
7. ISO 5211 High Platform International Standard
8. Manufacturer with large-scale batch production capacity
Eight characteristics and design execution standards of flange ball valves
01 Valve stem "O" ring third sealing design
When the valve stem rotates, the "O" ring can reduce the direct friction between the valve stem and the valve body, and can also play an auxiliary role in resealing the valve stem during low-pressure use. If the pipeline medium is gas,
The sealing effect of "0" is better than that of PTFE.
02 Valve stem explosion-proof design
The structural design of this valve stem and body can prevent valve misalignment and valve cavity damage
The pressure is too high and it rushes out of the valve body.
03 Design of sealing lines
Design a concentric circular positioning sealing structure between the valve body and the valve cover to prevent excess material leakage and movement when the sealing strip is compressed.
04 High Platform Design Compliant with ISO5211 Standard
The driver installation platform designed according to the ISO5211 standard can directly install various types of starters, and there are two PDC options for customers to choose from.
05 Submerged gland design
This cover design can be directly tightened by locking nuts A and B,
To prevent leakage at the sealing position between the valve stem and valve body,
No need to disassemble the starting device, convenient for on-site use.
Design of 06 Double layered Butterfly shaped Bullet Device
Two butterfly shaped spring pieces that have been pre compressed appear on the valve stem
Micro leakage will play a compensatory role in releasing its pre leakage
Tightly deform and compress the packing again.
07 Anti static Design
By pushing the spring behind the anti-static steel ball,
Make it in close contact with the ball groove,
Conducting static electricity through the friction between the ball and the valve seat on the valve stem.
08 Fire Protection Design
When a fire occurs on site, the valve seat is affected by high temperature
Processed from the valve body after burning or vaporization
The auxiliary metal valve seat plays a sealing role.
