1 zb941h- 25c dn400Electric stainless steel mining gate valvesummary:

Mining electric stainless steel gate valveThe main application is suitable for various systems such as petroleum, chemical, hydraulic, thermal power stations, etc. with nominal pressure PN1.6~16.0MPa and working temperature ≤ -29. Widely used in water conservancy, construction, fire protection, electricity, environmental protection, petroleum, chemical, pharmaceutical and other fields. What is the temperature range for the main products of Denso? 1550 ℃. Online, cut or open online media. Applicable media: water, oil, steam, acid, alkali, ammonia, urea, sulfur-containing natural gas, etc. The driving methods include manual, gear transmission, electric, pneumatic, etc.?

II zb941h- 25c dn400Electric stainless steel mining gate valveAdvantages:

1The fluid resistance is small, and its resistance coefficient is equal to that of a pipe segment of the same length.

2. Simple structure, small size, and light weight.

3. Tight and reliable. Currently, plastic is widely used as the sealing surface material for gate valves with good sealing performance, and it has also been widely used in vacuum systems.

4. Easy to operate, quick opening and closing, only need to rotate 90 ° from fully open to fully closed, making it convenient for remote control.

5. Easy to maintain, the gate valve structure is simple, and the sealing ring is generally movable, making disassembly and replacement relatively convenient.

When fully open or fully closed, the sealing surfaces of the valve body and valve seat are isolated from the medium, and when the medium passes through, it will not cause erosion of the valve sealing surface.

7. It has a wide range of applications, with diameters ranging from a few millimeters to several meters, and can be used from high vacuum to high pressure. When the ball rotates 90 degrees, it should appear spherical at both the inlet and outlet to intercept the flow.

3、 According to the nominal diameter of the valve, it can be divided into:

1Small caliber valve: nominal diameterDN<40mmThe valve.

2Medium caliber valve: nominal diameterDN50～300mmThe valve.

3Large diameter valve: nominal diameterDN350～1200mmThe valve.

4Extra large diameter valve: nominal diameterDN≥1400mmThe valve.

4、 Characteristics of the actuator:

1. Power supply: The motor is three-phase AC, 380V (special order 660V or 220V), 50Hz (special order 60Hz); The control line is 220V, 50Hz (special order 60Hz); Remote control is 24VDC.
2. Work environment:
(1) Environmental temperature: -20 to+60 ℃ (special orders -60 to+80 ℃).
(2) Relative humidity: ≤ 90% (at 25 ℃).
(3) Ordinary and outdoor types are used in places without flammable/explosive and non corrosive media; There are two types of explosion-proof products, dI and dIIBT4. dI is suitable for non mining working faces in coal mines; DIIBT4 is used in factories and is suitable for explosive gas mixtures in IIA and IIB level T1 to T4 environments.

5、 Purpose:

It is an AI controlled analog quantity used for regulating the flow rate of media in liquid, gas, and wind system pipelines. Electric valves can also be used for two position switch control in the control of large valves and air systems.

There can be AI feedback signals, which can be controlled by DO or AO, and are commonly seen in large pipelines and air valves.

Switch form:

The driving of electric valves is usually done by motors, and the opening or closing action requires a certain amount of time for analog measurement, which can be adjusted.
