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

Application:

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

Notes

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: What are the differences between the pneumatic ball valve and the pneumatic angle seat valve?: Features of pneumatic angle seat valve:1 、 visual position indication: it can be connected with limit switch or emergency manual device.2 、 easy to install: pneumatic head can rotate 360 degrees. One or two limit switches can be easily installed.3 、 advanced pneumatic controller: thickened engineering plastic shell, safe and reliable. Low wear piston structure with large capacity and low consumption. Self lubrication of internal components, maintenance free.4, with a variety of control methods: normally open, normally closed, double action.5. Require smaller pneumatic actuators: when the fluid flows over the stem, a smaller control head is optional.6, easy to connect: MAMUR standard connection, embedded metal connector.7, long-life Guide: Lease stem shaped Teflon (PTEE) sealed to avoid the import of stolen goods. Self lubrication, maintenance free. The stem is specially treated to ensure optimum fixation and automatically correct position.8. Without water hammer, the water hammer (water shock force) is absorbed when the fluid flows into the bottom of the valve stem.9, advanced valve body: flow is larger than ordinary angle block 30%, smaller size, better fluid flow pattern. 316 stainless steel body, Teflon seals, high temperature resistance, corrosion resistance. Life as high as seven million times

Q: What's the diameter of the 4 point ball valve?: 4 points is 0.4 inches, 1 inches =25.4 mm.Then the 4 point ball valve diameter is 10.16mm.

Q: The working principle of the track type ball valve: With its unique structure, the spool rotation separation open, new technology design of mechanical seal pressure, is the most prominent advantages of the sealing surface does not produce friction, long service life, low operation torque, even if the medium water content of solid particles, sediment, short fiber and other impurities, high concentration fluid flushing sealing condition of body harsh, can maintain good sealing, to ensure the engineering equipment maintenance period in the safe and reliable operation.

Q: How much pressure DN65 ball valve?: DN65 represents the nominal diameter of the valve, which is known as "2 and a half inches" of the ball valve!How big is the pressure? The pressure is expressed in PN, and the pressure levels are divided into: PN0.6, PN1.0, PN1.6, PN2.0, PN2.5, etc.

Q: Which one is more durable?: Butterfly type unused, a long handle used, the quality is very good.

Q: What does "ball Q41F-16" mean?: Q- ball, 4- flange connection, 1- DC channel, floating ball, F- sealing material for fluorine plastic, 16- nominal pressure of 16 kg, the valve body material for gray cast iron. If you want to know the details of the valve named model establishment, can refer to the JBT-308-2004 standard.

Q: What is the ball valve core?: The ball (ball valve as the cut-off valve in the marine and marine field), standard GB/T21465-2008 "valve terminology" is defined as: opening and closing parts (ball) driven by the stem, and around the valve axis for rotation of the valve. Can also be used to regulate and control fluid, strong shear force between the metal seat seal V type ball valve V type ball core and welding hard alloy, especially suitable for containing fibers, small solid particles and other media. Switch and multi way valve in the pipeline not only can flow, and flow diversion, flexible control of the medium, but also to turn off any channel to the other two channels. This kind of valve should be installed horizontally in the pipeline. In accordance with the way to drive the ball valve is divided into: pneumatic ball valve, electric ball valve, manual ball valve.

Q: And the cut-off valve is not the general name of gate valve and butterfly valve?What are the signs of differentiation?How about the use?: When the valve is opened, the opening height of the valve is 25% to 30% of the nominal diameter, the flow has reached the maximum, which means that the valve has reached full open position, so the opening position of the stop valve should be determined by the stroke of the discThe cut-off valve has the following advantages:The utility model has the advantages of simple structure and convenient manufacture and maintenanceSmall travel time, short opening and closing timeGood sealing, friction between the sealing surface of small, long lifeThe disadvantages of the cut-off valve are as follows:The resistance of fluid is large, and the force required for opening and closing is largerNot suitable for medium with particle, viscosity and easy cokingPoor regulation performanceType valve stem according to the position of divided threaded screw type, internal thread. Divided by the flow of media, there are straight through, DC type and angle type. Divided by the form of valve seal, a packing seal bellows seal valves and valve.The installation and maintenance of the cut-off valve shall pay attention to the following matters:The stop valve operated by the handwheel and handle can be installed in any position of the pipeHand wheel, handle and steering mechanism are not allowed to be used for liftingThe flow direction of the medium shall be in accordance with the arrow shown in the valve body

Q: Is the water inlet valve good or the ball valve well?: Good with the gate valve, the ball valve requires more space than the gate valve.

Q: How to distinguish between cold water valve and hot water ball valve?: Each of the valves has a sign on which the temperature and pressure are applied.There's something wrong with your question: what's the difference between a cold water valve and a hot water ball valve?Domestic valves, such as cut-off valves, cold water using the valve core, sealing materials, rubber, that is, cold water.Ball valve sealing surface is generally PTFE, can be used for hot water.
