stainless steel globe valve 'low into higher' and 'high in low'

high 'and' low 'refers to the globe Industrial Valves structure shape, looking down along the valve stem and valve stem coaxial convex part is' low ', on the side while connected to the valve cavity ( Relative to the 'low') The channel. Stainless steel valve generally is higher than that of low into the medium flow direction, this is according to the requirements of the globe valve cavity structure. Refers to the fluid enters the valve, in the valve cavity, the low flow upward and then out of the body. The top of the disc in the valve cavity.

medium from the bottom of the valve core to disadvantage is that the valve drive torque is bigger, 1 above is about to enter. 05 ~ 1. 8 times, stem by the axial force is big, the valve stem is easy to bend. Therefore, the medium into the way from below, generally applies only to small diameter globe valve ( (the following) , choose medium DN200 above the cut-off valve way in from the top. Electric Industrial Valves is generally adopts medium access from above. Medium entering way from above shortcomings just as opposed to enter below.

general design requirements, the DN 200 or less MMPN 4 or less. 0 mpa cut-off valve, the use of low into the above. When DN> When more than 200 mm, choose high to low. Globe valve disc for double disc structure. Because when diameter greater than 200 mm, because of the traffic, a lot of pressure on unit area, with low into the higher need a great deal of the opposite force to guarantee seal. It must stem increased, and must adopt impact handwheel or high torque worm gear device. Increase the volume of the valve and the product cost, and the effect not beautiful. High to low help seal ( Shut down after the media since pressure strengthens the sealing effect) Open, but due to overcome when the medium pressure, more difficult. 'Seal and medium pressure valve seal more closely, the stress state of the valve stem.

all in all, the valve with flow, the flow can be.
