PRODUCT DESCRIPTION<\/h2>\n

1.A threaded check valve is an automatic valve connected by a thread (thread).
\n2.It is mainly used in pipeline systems to prevent fluid reverse flow and avoid equipment damage or system failure caused by medium back flow.
\n3.Forward flow: Fluid pressure pushes the valve disc to open, and the medium passes normally.
\n4.Reverse flow: When the fluid pressure disappears or reverses, the valve disc automatically closes under the action of gravity\/spring force to block the back flow.<\/p>\n

FEATURES<\/h2>\n

1.Automatic opening and closing: no manual operation is required, and it is automatically controlled by the change of fluid pressure.
\n2.Low flow resistance: the flow channel is unobstructed when fully open, and the pressure loss is small (especially the swing type).
\n3.Reliable sealing: soft seal type is suitable for low pressure and normal temperature, and hard seal is resistant to high pressure and high temperature.
\n4.Installation restrictions: pay attention to the flow direction (the valve body is usually marked with an arrow) and the installation direction (some need to be installed vertically).<\/p>\n

APPLICATION<\/h2>\n

1.Water supply and drainage system: prevent water hammer effect at the pump outlet to protect the pump.
\n2.HVAC: avoid reverse mixing of hot and cold water in heating\/cooling pipelines.
\n3.Industrial pipeline: single-flow media systems such as compressed air and oil lines.
\n4.Household equipment: prevent back flow at the water inlet of water heaters and water purifiers.<\/p>\n

WORKING PRESSURE<\/h2>\n

Maximum working pressure 16 bar (230psi).<\/p>\n

STANDARD<\/h2>\n

Product testing is carried out in accordance with GB\/T13927 Industrial valve pressure test.
\nThe threaded connection is manufactured according to JB\/T7307-89 (pipe thread without thread seal).<\/p>\n

TEMPERATURE RANGE<\/h2>\n

0 \u00b0C to 80\u00b0C.<\/p>\n

COATING<\/h2>\n

Fusion Bonded Epoxy Coating.<\/p>\n
