Product Description

Product Description

The electromagnetic four-way directional valve is widely used in refrigeration systems such as household air conditioners, multi line machines, modular machines, unit machines, and heat pumps. By switching the refrigerant flow path through the four-way valve, the refrigeration mode and heating mode can be switched.

Product Features

1.Diversified design, divided into brass and stainless steel according to material. Applicable to fixed frequency, variable frequency, fixed frequency high-temperature, and variable frequency high-temperature series according to usage
2.Stainless steel four-way valve has low heat loss, high energy efficiency, high strength, and good vibration resistance
3.The stainless steel four way valve is made of stainless steel and meets the latest RoHS standards
4.Stainless steel valve welding is reliable, with a copper sleeve structure for connecting pipes, making it convenient for customers to weld
Energy saving coil optional
