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:Ball valve specifications 1/2 inches corresponding to DN?: [1] 1/2 is DN15, 3/4 is DN20, and 1 is DN25.[2] ball valve: ball valve (ball valve in the field of marine engineering and ships should be cut-off valve), refers to the ball with a circular hole for opening and closing parts, the ball with the stem rotation, in order to achieve Kai [1] closed action of the valve. Standard GB/T21465-2008 "valve terminology" is defined as: "open and close parts (spheres) driven by the stem, and around the square ball valve for the axis of the rotation of the valve.". Use 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. Classification of ball valve: 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:Stainless steel ball valve Q41F-16P DN80 weight is: The whole diameter is about 40kg heavyThere is a slight difference between the manufacturers

Q:What's the difference between T ball valve and L ball valve?: This is the code for the three way ball valve and the three way plug valve flow passage. The L shape can only connect the two channels perpendicular to each other, and the T shape allows the three channels to communicate with each other or to connect two of them.

Q:Into the tap valve, with globe valve or ball valve?: Just don't buy cheap goods, cheap ball valves use a period of time, gland leakage, spool corrosion must be replaced.

Q:Maintenance of PPR pipe ball valve is live or hot melt?: The ball valve is defined with the ppR/PE hot melt plastic pipe connected with the ball valve hot melt connection, ordinary ball valves generally use the threaded connection or flange connection.Hot melt connection is widely used in PB pipe, PE-RT pipe and other new pipe connections.Hot melt connection has the advantages of simple connection, long service life and easy corrosion.PPR pipes can only be connected by hot melt. There is a dedicated connection PPR tube double union copper ball valve, ball valve is full of copper, on both sides with PPR live tab.Ball valve (in the field of marine engineering and ships should be cut-off valve), standard GB/T21465-2008 "valve terminology" is defined as: "open and close parts (spheres) driven by the stem, and around the axis of the ball valve to rotate the valve movement.". 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.Ball valve was introduced in 1950s, with the rapid development of science and technology, production process and product structure of continuous improvement, in a short span of 40 years, has rapidly developed into a major valve category. In western developed countries, the use of ball valves is increasing year by year.

Q:Which is the smallest flow valve, globe valve or butterfly valve? Which one is the biggest?: Ball valve with minimum flow resistanceStop valve flow resistance maximum

Q:For example, how many sizes and pressures are used in the two piece?: A piece of ball valve is mainly manual, two piece ball valve for atmospheric pressure and high pressure, three pieces of ultra high pressure will be used, according to the actual caliber to determine

Q:What is a high handle ball valve? What's the difference between it and ordinary ball valve?: the valve handle can extend out of the insulation material, convenient operation.

Q:Replacement method of PPR hot melt ball valve: The above problems belong to the wire type, and the name is: double live catch valve, directly loosen the lock nut, replace the valve can be.When the valve is purchased, the merchant sells a full valve. When the change is made, both ends of the live joint lock nut are removed and the valve is directly connected with the original lock nut on the pipe.
