Forged steel gate Z41H-150LB Z41H-150LB with forging material processed from the gate collectively referred to as forged steel valve, forged material A105, F11, F5,304,304L, 316,316L, etc. China often say forged steel valve forged steel valve usually refers to small diameter, diameter range: DN10 ~ DN50; pressure range: GB PN16 ~ PN320, American Standard: Class150 ~ 2500. Forged steel gate valve is suitable for Class150 ~ 2500, operating temperature -29 ~ 425 ℃ (steel) or -29 ~ 500 ℃ (stainless steel) of small diameter pipe. Forged steel gate valve used to cut off or turn on the line of medium, use of different materials, can be separately applied to water, steam, oil, acetic acid, oxidizing medium, urea and other media, used more often in the oil pipeline All processing of gate with forging material collectively referred to as forged gate valve, forged material A105, F11, F5,304,304L, 316,316L, etc. China often say forged steel valve forged steel valve usually refers to small diameter, diameter range: DN10 ~ DN50; pressure range: GB PN16 ~ PN320, American Standard: Class150 ~ 2500, to adopt the US standard or national standard size production, processing, manufacturers are available from stock. Beyond DN50 caliber forged steel valve is required to build, less domestic demand mostly necking forged steel valve design, compared with the same caliber of cast steel gate traffic to be smaller, but the pressure and temperature ranges than steel Valves must be high, cast steel gate valve sealing performance is better than a lot better, live longer, the same direction as the flow unrestricted media with other gate. 1. forged steel valve fluid resistance, sealing surface by erosion distressed medium and small brush. 2. forged steel valve suitable for Class150 ~ 2500, operating temperature -29 ~ 425 ℃ (steel) or -29 ~ 500 ℃ (stainless steel) small-caliber pipeline, cut off or connected to the line media. 3. welded forged steel valve body simple structure, length short, good manufacturing processes for a wide range. The gate is placed vertically in the valve body, and cut-off valve flap valve body is placed horizontally, so the structure is shorter than the cut-off valve. 5. forged steel valve body inside the media channel is straight, without changing its flow direction medium flows through the valve, so the fluid resistance. 6. socket weld forged steel valve medium flow unrestricted, non-spoiler, do not reduce the pressure. Sealing performance is very good and full sealing surface by erosion small. 7. forged steel valve movement direction perpendicular to the direction of the fluid can be fully open and fully closed. Choice of different materials, can be separately applied to water, steam, oil, acetic acid, oxidizing medium, urea and other media. Point 1 is installed, the installation location, height, and export orientation must meet the design requirements, the connection should be firmly tight. 2, installed on various types of pipe insulation manual valve handle shall not be down. 3, must be visually checked before installing the valve, the valve plate should comply with existing national standards, "Universal Valve logo" GB 12220's. For working pressure greater than 1.0 MPa and the role played off the main pipe valves should be installed before the strength and rigorous performance tests, passing behind the prospective use. Strength test, the test pressure is 1.5 times the nominal duration of not less than 5min, the valve housing, packing should be no leakage as qualified. Tightness test, the test pressure of 1.1 times the nominal; test pressure in the test duration should be consistent with GB 50243 standards, in order to ram sealing surface leakage is qualified.
