Descrizione del prodotto:

Appearance structure: refer to foreign products, its features are light, practical, beautiful, good safety performance and so on. Under the condition that our company strictly implements the standard, the tensile and compressive strength of the valve body material is greatly enhanced, the force is uniform, and the appearance is beautiful. Sealing surface: Our company adopts oxygen welding surfacing technology of valve body and valve plate with reference to foreign oxygen welding technology, and forms copper alloy and valve casting as a whole to avoid the influence of temperature difference, and the friction coefficient between copper alloy and copper alloy is small, and the friction force is also reduced. Small , realizes the advantages of easy opening, practicality, beauty, good safety performance, and small operating torque.

The Non rising stem gate valves take small space to opearate and rising stem gate valves require more space. The construction of the non-rising is designe in such way that the stem of the gate valve is fully open when the handle is rotated as far as possible to the left and fully closed when the handle is rotated as far as possible to the right.
In both cases the handle is flush with the pipe because the mechanism inside the pipe opens and closes the valve without raising the stem.
Another advantage to the non-rising stem gate valve is that it is easier to padlock. Non rising stem gate valves are usually only used on clean liquids and gases.
