閥門技術說明 Technical speeification of valves
天津奧爾斯特礦業設備制造有限公司主要生產閘閥、截止閥、止回閥、球閥、安全閥、減壓閥、蝶閥、電磁閥、疏水閥等，通徑為DN15 ~ DN800mm，壓力等級為150LB ~ 2500LB（0.1Mpa ~ 42Mpa），工作溫度為 -196℃ ~ 680℃，材料主要有球墨鑄鐵、合金鋼、不銹鋼、20號合金等，并可根據用戶要求制造各種非標閥門。
Aurst company mainly produces gate valve, globe valve, check valve, ball valve, safety valve, reducing valve, butterfly valve, solenoid valve, steam trap, etc. The valve size is from DN15 to DN800mm, pressure rating is from150LB to 2500LB (0.1Mpa to 42Mpa), and the working temperature is from -196℃ to 680℃, valve materials mainly include cast iron, alloy steel, stainless steel, 20# alloy, etc. We also can manufacture all kinds of non-standard valves based on the client requirements.
Reasonable design, unique structure, convenient operation, fast opening and closing.
Reliable double sealed valve body manufactured from high wear-resistat imported polyurethane, long service life, the valve seat and flashboard have high wear resistance as special heat treatment.
The thickness of the valve seat and flashboard with double flange and bolt connection are increased by 10% than similar products of other manufacturers.
閥體內外均做防腐處理，避免生銹腐蝕。 Perform anti-corrosion processing both inside and outside prevent the valve body from rust corrosion.

驅動方式: Drive Mode
手動 Manual drive：借助手輪、手柄、杠桿或鏈輪等人力驅動，傳動較大力矩時裝有蝸輪、 齒輪等減速裝置。
Valve is driven by human power through hand wheel, handle, lever or sprocket, and so on, and also equipped with reducing device (like worm gear, gear, etc.) if the driving torque is larger.
電動 Electric drive：借助電機或其他電氣裝置來驅動。Use motor or the other electrical device to drive.
液動 Hydraulic drive ：借助（水、油）來驅動。Use water or oil to drive.
氣動 Pneumatic drive ：借助壓縮空氣來驅動。 Use compressed air to drive.
