Working principle and structure of four-way directional valve:The four-way reversing valve is composed of a main valve, a pilot valve and an electromagnetic coil. The pilot valve is used to control the main valve, and the differential pressure is used to switch the valve, so the reversing is flexibl

The four main parts of refrigerating system in cold storage include: refrigerating compressor, condenser, throttling device (expansion valve, capillary, etc.) and evaporator (air cooler) . The four main components and refrigerants become the necessary conditions for realizing the refrigeration cycle

The pressure controller has two main functions:

Direct-acting solenoid valve: Principle: when electrified, the solenoid coil produces solenoid force to lift the shut-off piece from the valve seat, the valve opens; when the power is cut off, the solenoid force disappears, the spring presses the shut-off piece on the valve seat, and the valve close

When the temperature of the cold storage reaches the set value, the temperature controller acts, the solenoid valve loses power, the compressor stops when the low pressure reaches the set value of the shutdown, when the temperature in the cold storage rises back to the set value, the temperature con

A refrigeration unit system is a large industrial refrigeration unit whose core component is the refrigeration unit. The unit consists of a compressor, condenser, evaporator and expansion valve, etc., and the cooling and cooling of air or fluids is realized through the concerted work of these compon

A pressure regulator is an essential component in a variety of applications, including:1. Automotive Industry: In the automotive industry, pressure regulators ensure that fuel delivery systems operate smoothly by controlling the amount of fuel delivered to the engine.2. Process Control Systems: Re

A refrigeration solenoid valve is a type of control valve used in refrigeration and air conditioning systems to regulate the flow of refrigerant gas through a system. It is typically controlled by a signal from an electronic module or controller, which sends a command to the valve based on sensor
