1, the rubber valve adopts the whole package, its good with performance and precise geometry size to ensure reliable sealing, long service life.

2, simple and compact structure, convenient operation, easy installation and easy maintenance;

2, at the bottom of the tank, large flow area, sizing smooth transition, no dirt accumulation phenomenon, small flow resistance;

3, resilient seal, zero leakage and long service life;

4, the valve inside and outside spraying epoxy resin coating, coating rubber damper as a whole, to prevent the corrosion and rust polluting the medium, not only for drinking, and can be used in the sewage system;

5, stem with three "O" type circle in sealing, low friction resistance, small operation torque, easy, for opening and closing without stuffing box leakage phenomenon, and under the condition of pressure and constant water replace o-rings.

6, soft-sealing gate valve can be used for adjusting.

7, have automatic adjustment function, through the guide valve plate and valve body, automatic calibration. Screw nut is embedded on the valve plate to ensure the center line of the valve stem and valve body centerline of automatically.

8, ensure that opening and closing more than 50000 times without damage, the valve plate closed tightly.

9, paint on the surface of the valve has the good, using polyester paint, paint color to blue.

Q:What does valve qz45x - 10q mean?
Crown valve pressWhat does Q stand for? I'm not sure. It's probably made of ductile iron"Z" means "gate valve"4 represents flange connection5 represents the dark bar (1 represents the Ming pole)X stands for rubber seal and soft seal10q stands for 10 pressure
Q:What is the difference between gate valve and gate valve? Is it the same valve?
The valve is driven by the valve stem to make vertical lifting of the plate inside the valve body.Gate valve is the same reason. The gate valve and gate valve have steel gate, parallel double gate and so on.So the gate valve and gate valve are the same valve. It's just a different name.
Q:What's the meaning of the gate valve model z41x 16Q?
Gate valve (Z) flange connection (4) wedge type single gate (1) rubber soft seal (X) -16 pressure) (Q)
Q:What is the difference between gate valve 41h-16c and 41w-16p?
According to the provisions of the JB/T 308-2004 valve type programming method:H== sealing surface material: Cr13 stainless steelC== body material: carbon steelW== sealing surface material: body, that is, with the same material bodyP== body material: chrome nickel stainless steel
Q:What gate DH10016, AM
The first Z represents the gate valve (the initial consonant of the Chinese phonetic alphabet for the gate); the second 2 represents the drive mode of the valve, that is, electro hydraulic drive.
Q:What's the difference between a soft seal gate valve and a hard sealed gate valve?
Soft sealing gate valve is rubber seal, F sealed, hard sealing gate valve is the medium of particles.
Q:What is gate well?
Explanation:Valve wells also called valve wells, underground pipelines and underground pipelines (such as tap water, oil, natural gas pipeline valve etc.) in order to facilitate the opening and closing part of network operation or overhaul when needed, a pit is a similar small room (or well), the valve installation in the pit where, for regular inspection, cleaning and dredging pipeline, to prevent the blockage of the pipeline project. The pit is called a well. There are valves, wells must have valves, but there is not necessarily a valve valve wells.
Q:What do you mean by forged steel gate valves 800LB DN20 SW?
Is the forged steel gate 800LB is DN20 on SW welding pressure
Q:The legend of gate valve and stop valve
When the valve is installed, the medium can enter from the bottom of the valve core and enter the two way from the top. Medium from the spool into the advantages of the valve closed when the packing is not under pressure, can extend the service life of the packing, and can be pressure in front of the valve in the case of replacement of packing work. Medium from the spool into the bottom of the shortcomings of the valve driving torque is larger, about 1.05~1.08 times above the entrance, the stem by the axial force of large, easy to bend the stem. To this end, the media from below to enter the way, generally only applicable to small caliber manual stop valve, to the valve closed, the media acting on the spool of force is not greater than 350kg limit. Electric cut-off valve is generally used to enter the media from the top way. The disadvantage of the medium entering from the top is just the opposite of the way it is entered below.Compared with the gate valve, the utility model has the advantages of simple structure, good sealing performance, and convenient manufacture and maintenance. The disadvantage is that the liquid resistance is large, and the opening and closing force is large. Gate and globe valves are fully open closed type valve, cut off or connected as the medium use, not as a control valve.The range of application of stop valves and gate valves is determined by their characteristics. In the smaller passages, the cut-off valve is used when required for better shutoff; in the steam pipe and the large diameter water supply pipe, the gate valve is generally used because of less fluid resistance.
Q:What is the size and length of the DN80 gate valve? 10 kg and 16 kg, respectively?
Valve structure length standards are PN16, short series for 203mm, long series for 280mm, flange size by PN16.
