2.Feature

GL41 series strainer is the series of a device, usually installed in a reducing valve, relief valve and the inlet water valve or other equipment, used to eliminate the impurity in the medium, in order to protect the valves and equipment normal use. The filter has the advanced structure, small resistance and easy drainage, etc. Applicable medium can be water, oil and gas. Screen according to user requirements, its features are basically the same type (Y), the internal parts are all made of stainless steel, strong and durable. When need to wash, just remove the removable cartridge, remove the filter out impurities, repack, use maintenance is very convenient. The filter size small, eye fine filter, small resistance, high effect, convenient installation and maintenance, low cost, short and discharge time, for the average small models, only 5 to 10 minutes.

Q: Is the valve clockwise?: The valve clockwise rotation of the handwheel is to close the valve, counter clockwise direction is to open the valve, the number above said valve opening rotating the handwheel clockwise along the colonel, to the above number 0 corresponding pointer is completely closed; in counter clockwise direction, to a maximum of 5 numbers above corresponding pointer, is the valve open to the largest degree.

Q: Remove the handle and lever the stem rotation with a wrench,: Monel alloy is mainly applied to the valve in the medium containing hydrofluoric acid.6, Hastelloy alloy is mainly used in the valve of strong corrosive medium such as dilute sulphuric acid7, titanium alloy is mainly applicable to all kinds of strong corrosive medium valveRecommendations for the GB standard of steel and ASME second A copies at American Standard. For American Standard steel can also see ASME B16.34

Q: Pump, valve, these belong to the material?: The pump belongs to the equipment (electromechanical equipment), and the valve belongs to the pipeline material.

Q: What is the choice of pneumatic valve or electric valve for ultrafiltration inlet control valve?: Now the UF system is basically full automatic system, that is to choose automatic valve. As for the pneumatic valve or electric valve, depending on your investment and the scene.

Q: According to the original valve installed on it, but never demolished, I am afraid to force over, will not be broken? The old valve, that part of the remaining three tubes tight.: Look, the valve you bought looks like PVC hot melt.. If the old valve and the elbow must be rejected with a hacksaw, hot melt and buy a new elbow and PVC section pipe for hot melt machine welding. From the picture didn't see traces of the thread,

Q: What does the RF of the valve mean?: Convex flange, RAISED, FACE,At 150#, 300#, height is 2MMAbove is 7MM,

Q: If the valve in the pipeline throttle, such as open and open 50%, the valve before and after the pressure of how to calculate, how the flow changes?: Well, it's not easy. And you do not give the specific structure of the valve, so there is no way to talk about the calculation. The simplest way is to install the pressure gauge and the flow meter on both ends of the valve, and read the data directly.

Q: What do you mean by the 16 bit coding of the valve type?: Valve model is by the type of valve, valve drive, valve connection, valve structure, sealing material, valve body material code to indicate.1. Valve types are Z- gate valve, P- drain valve, Q- ball valve, D- butterfly valve, J- stop valve, etc.;2, the valve drive mode code by letters said, common 2- electric hydraulic, 9- electric, 6- pneumatic, 5- bevel gear drive, 3- turbo worm; manual do not need to write out3, the valve connection form code with letters to indicate, 1- internal thread, 2- external thread, 4- flange type, 6- welding, 7- pairs clamp type, 9- clamp, 0- card sleeve;4, valve structure code, for example: 0- 1- flexible gate valve, open bar wedge type single gate, 2- rising stem wedge gate, 3- parallel single gate, 4- double disk parallel, 5- dark pole single wedge gate, 6- dark bar wedge gate, dark 7- parallel single gate, 9- dark pole parallel gate;5, sealing materials or lining materials were used R- T- austenitic stainless steel, copper alloy, X- rubber, S- plastic, N- nylon, F- fluorine plastic, H-Cr series stainless steel, hard alloy Y-, J- rubber lining, Monel M-;6, the body material code Z- K- gray cast iron, malleable cast iron, Q- ductile iron, copper and T- alloy, C- steel, P- chromium nickel stainless steel, R- stainless steel chromium nickel molybdenum, chromium molybdenum vanadium steel V-.For example: electric, flanged, rod wedge gate valve, sealing surface material by direct processing, nominal pressure PN0.1MPa of the valve body is made of grey cast iron gate valve: Z942W-1 electric wedge gate valve.

Q: What's the material of j41h-16p's valve?: Stop valve characteristics:(1) the structure is simpler than the gate valve, and the manufacture and maintenance are more convenient.(2) the sealing surface is not easy to wear and scrape, good sealing, when opening and closing, there is no relative sliding between the valve and the sealing surface of the valve body, so the abrasion and abrasion are not serious, the sealing performance is good, and the service life is long.(3) when opening and closing, the valve stroke is small, so the cut-off valve height is smaller than the gate valve, but the structure length is longer than the gate valve.(4) the opening and closing moment is big and the opening and closing are more strenuous.(5) large fluid resistance, due to the valve in the medium channel is tortuous, large fluid resistance, power consumption.(6) the flow direction of medium nominal pressure PN is less than or equal to 16MPa, commonly used downstream, medium from the valve under the direction of flow; nominal pressure PN = 20MPa, using reflux, medium from the valve on the downstream direction to increase the seal. When used, the cut-off valve medium can only flow in one direction, can not change the direction of flow.(7) when fully open, the disc is always subject to erosion.
