The Allway Valve® Rising stem brass seat gate valve that is created by China manufacturers and suppliers can see the lead stem and drive to lift or lower the disc through the stem and the steering wheel screw . The drive thread on the stem is outside the valve body. According to the movement direction and position of the stem, the opening and closing of the gate plate can be intuitively judged.
The high quality BS5163 metal seat gate valve made in China is British standard gate valve design standard. The fluid resistance is small, the opening and closing moment is small, the opening and closing is less effort, the medium flow direction is not restricted, no turbulence, no pressure reduction, the structure length is short, the sealing performance is good, the shape is relatively simple, the casting process is good, and the application range is wide.
F5 metal seat gate valve made in China factory face to face dimension is longer than F4 gate valves. It often used in fire and industrial systems, generally installed at a high distance from the ground.This valve overcomes the general gate valve seal poor, elastic fatigue, easy to rust and other defects.It is the replacement of the traditional gate valve, which makes use of the elastic gate plate to compensate for the trace deformation and achieve good sealing effect.
F4 metal seat gate valve made in China is reliable sealing, excellent performance, beautiful shape, good interchangeability.The sealing face of gate plate and seat is made of the latest engineering ceramic material, developed and manufactured according to the advanced technology introduced from the United States. It has strong wear resistance, high temperature resistance, corrosion resistance and abrasion resistance, and its service life is more than 10 times higher than the ordinary alloy sealing face.
Rising Stem Metal Seat Gate Valve from China factory can see the lead stem and drive to lift or lower the disc through the stem and the steering wheel screw . The drive thread on the stem is outside the valve body. According to the movement direction and position of the stem, the opening and closing of the gate plate can be intuitively judged.
non rising stem brass seat gate valve which China manufacturers supply uses the compensation function of the elastic gate plate to produce the trace deformation to achieve the good sealing effect. The valve has the remarkable advantages of light switch, reliable sealing, good elastic memory and long service life.Hard sealed gate valve can be widely used in tap water, sewage, construction, food, electric power, medicine, metallurgy, light textile, energy system and other fluid pipelines as a regulating and closure device.
