Product Usage
The opening and closing part of the protective gate valve is the gate, and
the movement direction of the gate is perpendicular to the direction of the
fluid. The gate valve can only be fully opened and fully closed, and cannot
be adjusted or throttled. The protective gate valve is a reference to some
foreign products by our company, with innovation in design and
improvement in process; the internal quality and appearance of the product
have been improved, and it is designed and manufactured in strict
accordance with national standards for valves.
Features
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.
