Product description of J41H / w / y Japanese standard stop valve:
The J41H / w / y daily standard stop valve produced and sold by Woci valve (Shanghai) Co., Ltd. is suitable for cutting off or connecting the pipeline medium under various working conditions such as petroleum, chemical industry, pharmaceutical, chemical fertilizer and electric power industries with working temperature of - 29 ~ 550 ℃. The driving modes of Japanese standard stop valve include manual, gear drive, electric and pneumatic. The sealing surface of valve seat is made of cemented carbide and the pressure level is 10K / 20K.
Detailed introduction of J41H / w / y Japanese standard stop valve:
The opening and closing part of the Japanese standard stop valve is a plug-shaped disc, the sealing surface is flat or conical, and the disc moves in a straight line along the center line of the fluid. The movement forms of the valve rod include lifting rod type (the valve rod is lifted and the handwheel is not lifted), and lifting rotating rod type (the handwheel rotates and lifts with the valve rod, and the nut is set on the valve body). The stop valve is only applicable to full opening and full closing, and regulation and throttling are not allowed.
