LR1R220 is a multi-purpose, low-pressure cutoff switch used in hydraulic and pneumatic applications. It is designed to provide protection from over pressure on systems as well as protect from improper installation. The LR1R220 has a switch rating of 20A and a temperature range of -40°F (-40°C) to +176°F (80°C). The LR1R220 consists of a body, a pressure plate, a valve spring, a pilot valve, and a switching mechanism.

The LR1R220 is used in various applications such as hydraulic power systems, hydraulic pumps, and pneumatic systems. It is also used as a safety device in various industrial applications. It is capable of operating at high pressure levels, which makes it ideal for controlling and protecting components that may otherwise be damaged by over pressure or improper installation.

The working principle of LR1R220 is based on the pressure plate and valve spring. As the pressure on the pressure plate increases, the valve spring is pushed against the pilot valve, allowing the fluid to move through. This causes the pressure to increase, and when the pressure reaches a certain level, the pilot valve is opened and the fluid is allowed to move into the switch mechanism. When the pressure is released, the valve spring returns to its original position, allowing the fluid to flow back through the pilot valve and into the system. The process is regularly repeated until the system is back to its original pressure level.

The LR1R220 also operates as a pressure reducing valve, regulating the pressure to a level which can be controlled by the user. The precise way in which it functions depends on the setting of the valve. Furthermore, the LR1R220 is equipped with a bypass valve, which allows the pressure fluid to bypass the switch when pressure on the system increases beyond the user-defined setting.

The LR1R220 is also extremely easy to install and maintain, and is designed to handle large pressures. It can be used in a wide range of applications, making it a versatile and reliable protection device. The LR1R220 has been specially designed for the purpose of providing reliable protection and ensuring that pressure levels are kept within a safe range.
