Established in 1993, Guanfa Valve Manufacture Co., Ltd. is specialized China electric valve manufacturer and distributor of valves, hoses, tubes and pipes. Our oem electric valves are suitable for acid, alkali, water, steam, seawater, coal gas and natural gas. They are widely used in petroleum, chemical, paper making, fertilizer, brewing and metallurgy. The use of specialized software of Pro/E and CAD has shorted the P&D and trial manufacture cycle, and greatly improved the service life and dependability of products. Our high-quality products have been exported to the North Amercia, UK, USA, Germany, Italy, India, France, Australia, Japan.

SEV Electric Expansion Valve is mainly used in refegaranting and air conditioning
for precise control of refrigerant flow. Characteristic: Total-enclosed. Step-motor drive
Complete close can omit magnetic valve. Linear flow change. Wide range of cooling capacity
High- resolution, 0.0000393 foot (0.001mm)/step, Max. action parameter 12500 steps
Wide application (Can be compatible with most CRCs,HCFCs and HFCs). Original valve body transmit with separable extend drivers through magnetic induction. Low power consumption 7.2W(3.6W/phase). Scaled with permanent rigid lubricating material. Supported by MVC Electric Expansion Valve Controller, make SEV Electric Expansion. Valve convenient like traditional thermostat expansion valve. Two main parts of SEV Electric Expansion Valve, Valve body and throttle step motor. The step motor is on the top of valve extend step motor can be separated by valve body, it motivate the core of valve to up and down by magnetic induction so as to precise control refrigerant flow.

Available for throttle equipment with cooling capacity between 50USRT and 250USRT.
Unique magnetic induction, separated drive structure to ensure the refrigerant doesn't pour out and regulate the flux of the refrigerant exactly. Chang flux energy saving technique ensures the high precision balance, high quality control, and running with high efficiency.
Total enclosed. Step motor. Completely close function. Linear flow change. Wide cooling capacity range. Wide application. High resolution:0.0000393 inches(0.001mm)/step-Max.12500 steps. Original valve body transmit with separable extend drivers through magnetic induction low power consumption 7.2W(3.6W/phase). Copper ODF connections and brass SAE connections for ease of installation. Hard self lubricating materials sealed
High reliability and longlife. SEV Electric Expansion Valve can compatible with current halocarbon refrigerants such as CFCs, HCFCs and HFCs, available for R22 nominal capacity including 175KW, 350KW, 615KW and 875KW
