■Product Characteristic
This valve has compact structure, reasonable design, good valve rigidity, fluent channels and small resistance modulus. Stainless steel and hard alloy seal surface makes the valve has a long service lifetime. Flexible graphite packing make the valve has a credible seal performance and portable operate manner. The drive manners are hand wheel drive, electric drive, pneumatic drive and worm-gear drive. There are three structure types: flexibility wedge signal flashboard, rigid wedge signal flashboard and double flashboards. It is applied to get through or truncate the medium on the petroleum chemical, coal-fired power plants and other oil, steam pipelines.
