Lf42 series pressure switch is used in water supply
pressure protection of water inlet. This series include two
models LF42H(high pressure protection) and LF42L(low
pressure protection). LF42H is the high pressure
protection switch model. If the pressure of the pressure
vessel transferred reaches the setting value while the
vessel is full filled with water, the switch will cut off the
circuit to make the pump stop. So the pump will not be
damaged. LF42L is the low pressure protection switch. If
the pressure of water inlet lower than set value, RO will
not work and keep dewatering, then the switch will cut
off the circuit to make the pump stop. It can prevent the
booster pump still working without water which may
lead to the damage of the circuit. If the pressure of the
water inlet returns to the lowest set volume, the pump
will work again. Specification

LF5D series are pressure differential switches which
normally used in water or oil fluid to control the pressure
differential of the outlet tube and inlet tube. Bellowing is
one of the typical application: install the valve in the
pipeline which near the water(oil) pump, when the
pressure differential of the two sides of the system
increasing or decreasing and exceed the setting value,
the valve will open. Then the system pressure differential
will reach to the normal circulate. Both two sides of LF5D
series have a high sensitive components, the switch will
act to control the system of the equipment such as
motor driven valve while the pressure differential
changes.

La serie ITA5D son interruptores diferenciales de presión que normalmente se usan en agua o fluido de aceite para controlar la presión diferencial del tubo de salida y el tubo de entrada. El siguiente es una de las aplicaciones típicas: instale la válvula en la tubería que está cerca de la bomba de agua (aceite), cuando el diferencial de presión de los dos lados del sistema aumenta o disminuye y excede el valor de ajuste, la válvula se abrirá. Entonces el diferencial de presión del sistema alcanzará la circulación normal. Ambos lados de la serie LF5D tienen componentes altamente sensibles, el interruptor actuará para controlar el sistema del equipo, como la válvula accionada por motor, mientras que el diferencial de presión cambia.
