PRODUCT DESCRIPTION<\/h2>\n

1.A grooved pressure relief valve is a valve used to release over pressure in a pipeline system and protect the system safety.
\n2.It is usually used in conjunction with a grooved pipe connection system.
\n3.Normal state: When the system pressure is lower than the set value, the spring force makes the valve disc\/diaphragm close to the valve seat and the valve is closed.
\n4.Over pressure relief: When the pressure exceeds the set value, the medium pressure overcomes the spring force, pushes the valve disc open, and releases excess pressure.
\n5.Pressure recovery: After the pressure falls back to the safe range, the spring pushes the valve disc to reset and the valve closes.<\/p>\n

FEATURES<\/h2>\n

1.Quick installation: Groove connection does not require welding or thread processing, saving installation time and cost.
\n2.Automatic response: No external control is required, and it automatically opens and closes based on system pressure changes.
\n3.Adjustable pressure: The pressure relief threshold can be adjusted according to needs, with a wide range of applications.
\n4.Easy maintenance: Modular design supports quick disassembly and replacement of seals.
\n5.Compatibility: Suitable for a variety of media such as water, gas, and firefighting foam.<\/p>\n

Application<\/h2>\n

1.Fire protection system: protect sprinkler pipes, fire hydrants, etc. from water hammer or pressure fluctuations.
\n2.Water supply and drainage system: prevent over pressure caused by pump start and stop or valve misoperation.
\n3.Industrial pipeline: protection of pressure vessels or pipelines in the fields of chemical, HVAC, energy, etc.
\n4.High-rise buildings: balance the water pressure difference between floors to avoid pipeline rupture.<\/p>\n
