As well known by industry insiders, un gate valve is a gate used to open and close. The movement direction of the gate is perpendicular to the direction of the fluid. The gate valve can only be fully opened and closed, and cannot be adjusted or throttled. So rising gate valve is also one kind of gate valve. By turning the handwheel, the threads of the handwheel and the valve stem move forward or backward, and the valve plate connected to the valve stem moves up or down to realize the opening and closing function. In summary above, this is the rising gate valve we use.

Advantages of valves we produces:

La résistance du fluide est faible, and the sealing surface is less eroded and corroded by the medium. Saving effort when opening and closing. The flow direction of the medium is unrestricted, does not interfere with the flow, and does not reduce the pressure. Simple shape, short structure length, good manufacturing process and wide application range. Certainement, everything has two sides as well. Though rising gate valves own enough advantages and worth to use, there are some disadvantages about this kind of rising gate valves below,

Disadvantages of the rising stem gate valve:

It is easy to cause erosion and scratch between sealing surfaces, and it is difficult to maintain. (Certainement, our products meet high standard in valve industry, to guarantee rising gate valve’s long life) The overall size is large, which requires a certain space to open, and the opening and closing time is long. The structure is relatively complex. It’s a good suggestion to purchase products from guaranteed valve manufacturers to lower their disadvantages. And a quality product can improve efficiency in use. So TWT Valve supplier always is priority to recommand.
