Hard seal concealed stem gate valve

OVERVIEW

Civil air defense brass core gate valve, in addition to the
advantages of elastic seat seal gate valve, in an emergency civil air defense brass core gate valve opening and closing will not be affected by rust or long-term use, civil air defense brass core gate valve can be used in the civil air defense engineering system, in the pipeline flow is unstable or pipeline emergency vibration under the combination of civil air defense brass core
gate valve and explosion-proof wave valve can ensure the
normal operation of the pipeline system shock absorption,
open and close for easy maintenance.

FEATURE

Shape and structure: It has the advantages of lightweight, practical, beautiful and good safety performance. In the case of our company's strict implementation of standards, the
tensile and compressive strength of the valve body material is greatly enhanced, the force is uniform, and the appearance is beautiful.
Sealing surface: The valve body and valve plate oxygen
FUwelding surfacing technology are adopted to form the brass VAL alloy and valve casting as a whole to avoid the influence of
temperature difference, and the friction coefficient between the brass alloys is small, and the friction force is also reduced, which realizes the advantages of light opening, practicality, beauty, good safety performance and small operating torque.
