Z41T rising stem wedge gate valve is an automatic valve, which relies on the pressure of media to press the gate sealing surface to the other direction of the valve seat sealing surface, making the two sealing surfaces closely match to ensure the sealing effect.The gate plate of rising stem wedge gate valve can be made into a whole, which is usually called rigid gate plate.Or improve its process, so as to make up for the deviation in the process of processing, this kind of gate is called elastic gate.
1. Z41T rising stem wedge gate valve features:
1. Compact structure, reasonable design, make the valve rigid, unobstructed channel, medium resistance is small;
2. The sealing surface is made of stainless steel and hard alloy, with long service life;
3. The structural type can be divided into various types, such as elastic wedge type single ram or rigid wedge type single ram and double ram, etc.;
4. Choose flexible graphite for packing, with reliable sealing, convenient and flexible operation;
5. Drive mode can choose manual, pneumatic, electric, gear transmission, etc.
