Specifications

Gate valve

Gate valves supplied by our company are available in temperature classes L, P, R, S, T, and U specified in API 6A.

Gate valves to be used in the 350°C or 650°C high temperature can be supplied on request. Fire-proof gate valves also can be supplied to API 6A.

Gate valves manufactured by our company are available in 2000psi, 3000psi, 5000psi, 10000psi and 15000psi working pressure, material classes from AA through FF, product specification levels (PSL) from 1 through 3 and performance requirement (PR) 1, 2.

Both sealing faces of gate are wedge type structure,and hand wheel can be loaded to adjust the fastness of attachment of gate and valve seat.

The sealing face of gate and seat is overlaying-welded with hard alloy with erosion and corrosion resistance

Nominal bore:2 1/16"~4 1/16"

Q: What do you mean by "2" and "200 CF8M"?: CF8M is stainless steel, and 2 is caliber 50200 and should also be bore

Q: What are the advantages and disadvantages of flat gate valves?: The advantage of flat gate valve is that the flow resistance is small, and the flow resistance is similar to the flow resistance of short valve. The flat gate valve with guide hole is installed on the pipeline and can be directly cleaned with the cleaner. As the gate is sliding on the two seat surface, the flat gate valve can be applied to the medium with suspended particles, and the sealing surface of the flat gate valve is actually positioned automatically. The seat seal surface is not subject to thermal deformation of the valve body. Moreover, even if the valve is closed in cold condition, the thermal elongation of the stem will not cause the seal to be subjected to overload. The length of the structure is much shorter than that of the ball valve, and it is easier to start. Light plate gate valve is more refined, but the effect is exactly the same.

Q: Why is gate valve or butterfly valve used for water pump?: General pressure is small, use the butterfly valve, when the pressure is big, use the gate valve. The two main function of the valve is to adjust the flow and easy to overhaul.Zibo Boshan new Duke water supply equipment

Q: The difference and use of gate valve and stop valve: Medium flow is unrestricted.When opening fully, the sealing surface is eroded by the working medium smaller than the cut-off valve.The shape is relatively simple and the casting process is better.The valve is used in the system is relatively large, to close the gate off system; and the valve is used in the system is relatively small, and to adjust the flow quantity of the system, can not be closed gate and globe valves of different specifications for many kinds of occasions, the valve rod valve the dark bar gate valve, wedge gate valve, single valve, multi valve valve body structure is different, large volume.

Q: Does the relief valve have a gate valve?: No The front end must be in control.

Q: Gate valve type Z40Y, Z40H letters - what does that mean?: According to the provisions of the JB/T 308-2004 valve type programming method:Z== gate valve4== connection: flange0== structure: wedge type elastic RAMY== sealing surface material: hard alloyH== sealing surface material: Cr13 stainless steel

Q: What is the difference between Z41X gate valve and Z45X gate valve?: All flange soft sealing gate valve, but 41X is Ming bar, 45X is dark pole

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: About fire valve is gate valve or butterfly valve problems?: Disease is generally in accordance with the design requirements, regardless of the butterfly or tie hair to meet the requirements, are two-way valve.

Q: Why does the centrifugal pump start and stop in the case of closing the gate valve?: After the valve is closed to stop the cause of centrifugal pump outlet valve is closed to stop the pump to prevent the flow back into the pump, impeller, impeller in reverse, part of the mechanical seal in the pump pump impeller reversal will have adverse consequences, serious damage to the centrifugal pump, to close the valve after the shutdown.
