Introduction
DIN flange stainless steel bellows seal globe valve is used to regulate flow of pipelines. The valve body is made from GS-C25, 14308 G-X6CrNi18-9, 1.4408 G-X6CrNiMo18-10, 1.4306 G-X2CrNi 18-9 and 1.4435 G-X2CrNiMo17-12-2. The disc is made from 1.4006 X10Cr13, 1.4301 X5CrNi18-10, 1.4401 X3CrNiMo17-132, 1.4306 X2CrNi19-11 and 1.4435 X2CrNiMo17-12-2. While the bellow assemble of stop valve is made from 1.4878 X12CrNiTi18-9, 1.4401 X3CrNiMo17-132, 1.4306 X2CrNi19-11 and 1.4435 X2CrNiMo17-12-2.
Application of Stainless Steel Globe Valve
1. DPI bellows seal globe valve is suitable for regulate and throttle tag water and sewage.
2. It can be employed in such pipelines of chemical, metallurgy, medicine, construction, etc.
3. Beyond that, such stainless steel valve is fit for pipelines of foodstuff, textile, vessel and energy system.
Advantages of Stainless Steel Globe Valve
1. DPI stainless steel globe valve enjoys long service life.
2. It has excellent sealing performance.
3. The open torque is small.
Features
(1) DIN flange stainless steel globe valve features simpler structure and easier maintenance when compared with gate valve.
(2) The disc stroke is not long when the valve is on and off. Its height is a bit lower than that of gate valve, yet the structure length is longer.
(3) The valve stem axis of this stop valve is vertical to valve seat sealing face.
(4) When nominal pressure of medium flow direction is under 16MPa, medium flows up from lower disc. When pressure is above 20MPa, medium flows down from upper disc, which can help intensify sealing performance. When in operation, medium flows in single direction and can’t change direction.
