High-pressure self-tight sealing valve

151 high-pressure self-tight sealing valve Name: self-tight sealing valve; also known as: pressure from the tight valve Model: flange J41Y, welding J61Y, internal thread J11Y use - high pressure self-tight sealing valve high pressure high temperature, thermal good; sealing surface wear resistance, abrasion, wear and corrosion, good sealing performance and long life. Most suitable for thermal power industrial systems, high temperature systems petrochemical and metallurgical industries, such as pressurized water, steam, oil, superheated steam piping. Description - high temperature and pressure using a self-sealing valve forged steel structure design, when the pressure is higher the better sealing performance. Deflector plate structure, when the valve is open, baffle plates in the original position of the spool, the media from flowing through the diversion well plate, avoiding direct scour media for the seat, make the life of the valve seat greatly extended and reduces leakage due to erosion caused by the valve seat, and because of the medium flowing through the diversion uniform plates, the ability to reduce fluid loss, ensuring the normal flow parameters of the valve - Nominal: ≤4500LB interface Size: 1 / 4-2 "Temperature: -20 ℃ ~ + 425 ℃ ~ + 570 ℃; manufacturing materials: A105,304,316,316L, F91, F22 Medium: all kinds of gas, oil, water, gas, etc. a variety of non-corrosive or highly corrosive media
