The Safety Valve KH 1.406 is a type of safety valve commonly used in pressure vessels, such as hot water geysers or boilers. It is designed to release pressure from the vessel when the pressure exceeds the preset limit, thereby preventing the vessel from exploding or causing damage.

The KH 1.406 Safety Valve is a spring-loaded valve that opens automatically when the pressure inside the vessel reaches the set pressure. It has a brass body and a stainless steel spring, and is capable of handling pressures up to 10 bar. The valve is designed to be mounted directly onto the vessel, typically on the top or side, and is secured in place with a threaded connection.

The KH 1.406 Safety Valve is known for its reliability and durability, and is commonly used in both residential and commercial settings. It is important to follow the manufacturer's instructions when installing or replacing a safety valve, as incorrect installation can result in damage to the vessel or even injury to personnel.
