YK pressure controller series
Genera:
YK series pressure controller (also called pressure switch) is a more advanced mini controller in the world and
is researched and designed by using special material and process on the basis of absorbing and digesting technical
advantages of same kinds of product both at home and abroad. The properties of the product are reliable and its
installation and application are very convenient. It is wide used for heat pump, oil pump, gas pump, refrigeration set of
air-condition and equipment where needs to adjust medium pressure itself and pressure protection.

Principle of work:
When the lift of pressure to be controlled in the system is over the set value, the pressure in the system will drive
mini butterfly metallic film and produce instant displacement and push inch switch to off (or on) and take place over
voltage protection.When the pressure of medium to be controlled is low than the set value, the mini film sheet will be
jumped towards opposite di
