Product Description:

Stainless Steel Ball Valve

Features and Benefits:
  • Full Port Design
    Full port construction improves flow characteristics for greater process efficiencies

  • Blow-Out-Proof Stem
    Stem is bottom loaded to prevent removal when valve is in service

  • Locking Device
    Enables plant personnel to secure valve in open or closed position when manually operated

  • Live-Loaded Stem Packing
    Provides constant load on the stem seal and extends service life

  • Corrosion Resistant
    Made of 316 stainless steel (A351 Gr. CF8M) for greater chemical resistance and longer service life


Offshore / Oil / Gas / Chemical / Water / Wastewater / Marine


The specifications can be designed and satisfied for customers’ special requirements. The product is designed by adopting L.Lai’s high technologies. We have obtained certificates of SGS ISO 9001:2008.

Q:The difference between gate valve, ball valve and butterfly valve
Gate valve: there is a flat plate in the valve body which is perpendicular to the direction of the medium flow, and the plate is lifted and closed.Features: good tightness, fluid resistance small, open and close force is small, widely used, also have to regulate the flow performance, generally applicable to the large diameter of the road.Ball valve: the use of a hole in the middle opening of the ball as the spool, by rotating the ball to control the opening and closing of the hair.Features: the structure is simpler than the gate valve, small size, low fluid resistance, and can replace the role of gate valve.Butterfly valve: closure is a disk-shaped, around a fixed axis rotation of the valve body.The utility model has the advantages of simple structure, small size and light weight, and is suitable for making larger diameter valves. As the sealing structure and materials are still problems, it is only used for low pressure, for the transport of water, air, gas and other media!Own code words, hope to adopt!
Q:What is the difference between ball valve and plug valve?
2., simple structure, small size, light weight.3. close and reliable. The utility model has two sealing surfaces, and the sealing surface material of the ball valve is widely used in various kinds of plastics, and the sealing property is good, and the sealing can be realized completely. It is also widely used in vacuum system.4 easy operation, open and close rapidly, from fully open to fully closed as long as 90 degree rotation, facilitate remote control.5., maintenance is convenient, ball valve structure is simple, the sealing ring is generally active, disassembly and replacement are more convenient.6. in full open or full closed, the ball and valve seat sealing surface and dielectric isolation, the media through, it will not cause erosion of the valve sealing surface.7., a wide range of applications, from small diameter to a few millimeters, large to several meters, from high vacuum, high pressure can be applied.8., because the ball valve in the opening and closing process of wiping, so it can be used in suspension with solid particles in the medium. Therefore, the landlord can choose the right valve according to their own conditions, and I hope to help you.
Q:What does 1000WOG mean on a ball screw valve?
It's also a standard, huh?
Q:What does the sealing surface of the ball valve stand for HF?
HF= hard solder material in valves Q347HF, -16C, welded with CoCr or NiCr alloy.
Q:The difference between globe valve and ball valve
Q:In the wet alarm valve usually kept under working condition, alarm test ball valve state usually is closed or open?Because the alarm performance test on the pressure switch and hydraulic alarm, can be tested by open test ball valve, the bar working condition, the valve is closed or open? If so, if there is a police situation, if the police? If it does, it doesn't always call the police Seek expert advice.
Connect the valve in the hydraulic alarm above is normally open, water valve is normally closed, when the test fire, put out waterproof valve hydraulic alarm alarm, pressure switch module, spray pump inside the pump starts automatically. The end of the spray can be drained out or drained, and the pump can also be started
Q:Heating live catch valve DN15 straight DN15 angle what does that mean?
As shown in the figure: straight DN15 is: straight through both ends, such as diameter of 15mm, angle DN15 is: bifurcated end nominal diameter 15mm.
Q:Water heater ball valve is not very easy to pull, why does it feel bad?
Use the hair dryer, hot air gear to blow for a while, slowly screw, a bit loose, continue to screw, you can completely screw, and more than a few twists and turns, long time does not move, it will be stuck
Q:DN80/DN100/DN125 how big is the outer diameter of the ball valve flange?
In addition to the three common, flange standard complex, a long story.All kinds of standards, there is a little difference in thickness, diameter of flange, bolt hole number, but the flange bolt hole parameters of the same pressure level (bolt circle diameter K, bolt diameter L, bolt number N) are the same.
Q:Valve and ball valve is the same thing? Don't know don't speak
Ball valves belong to a large class of valves, valves include gate valve, butterfly valve, check valve, globe valve, ball valve, trap valve, safety valve, etc. all valves
