The opening and closing part of stainless steel flanged gate valve Z41W is wedge disc, the movement direction of wedge disc is perpendicular to the fluid direction, the gate valve can only be fully open and fully closed, can ‘t be adjusted or throttled. Wedge disc has two sealing surfaces, the two sealing surfaces of most common mode of gate valve form wedge, the wedge angle vary with the valve parameters, Usually the angle is 50 , and it is 2 ° 52 when medium temperature is not high. The wedge disc of wedge gate valve can be made into one piece, which is called the rigid wedge disc; It can also be made into wedge disc which produces small quantities of deformation in order to improve its manufacturability, to make up the deviations of sealing surface angle arising during processing, this wedge is disc called the flexible wedge disc.

Stainless steel flanged gate valve is widely used as opening and closing devices to connect or block the medium of oil, steam pipeline in petrochemical, power plants, etc.


Stainless steel flanged gate valve has the following advantages:

1, Compact structure, reasonable design, good rigidity, smooth channel, low flow coefficient

2, Sealing surface is made of stainless steel and hard alloy, it has long service life.

3, Flexible graphite is used as packing, sealing is reliable, and operation is flexible.

4, The driving modes are manual, pneumatic, electric, gear drive

5, The construction are flexible single wedge disc, rigid single wedge disc and double wedge disc type
