Are suitable for blowdown sealing equipment which is controlled by all kinds of pressure，temperature and medium of middle and small caliber piping or stop piping medium，the time of blowdown sealing is short，the installing height is on the small side， directed sealing.Not used in the occasion of adjustable flow.

One、basis structure of globe valves：
1.The J41F46frankwayfluoro plastic lined、J45F46 directed current、J44F46 angleglobe valves are widely used in the area of the soil、chemi al and industry pipe system for the shut-off function because of the characteristic of compact structure， flexible open and close， good erosion-proof performance and short process， but the globe valve can't be used to adjust flux.l ext the rapid-speed medium flow destroy the sealing cover.
2.Petal and pole of valve are designed as a whole to avoid the inner parts dashing out of the valve due to the pressure wave.

Two、criterion of design：
It is in compliance with GB 12233， GB 12235， ANSI B 16.34 standard.

Three、way of drive：
Manual， gear-driven， pneumatic and power-driven.
