Mechanical A/C compressor valve Calsonic CSV717 CWE615 CWV616 CWV618 Nissan X-Trail
Product Overview
The mechanical control valve is installed inside the Calsonic air conditioning compressor and regulates its performance depending on the operating parameters of the system. The valve is used in compressor types CSV717, CWE615, CWV616 and CWV618. A faulty valve can result in weak or unstable cooling, intermittent loss of cold, or improper compressor operation. This is a mechanical valve with no electrical connection. To make the correct selection, you need to check the model of the installed compressor and compare the shape, length, location of the O-rings and the design of the standard valve with photographs of the product. When to check the mechanical compressor valve: The air conditioner is not cooling enough; cold appears unstably or disappears periodically; The efficiency of the air conditioner changes during operation; the compressor is working, but its performance is not adjusted correctly; Diagnostics indicate a malfunction of the compressor's internal control valve. Compressor types: Calsonic CSV717 Calsonic CWE615 Calsonic CWV616 Calsonic CWV618 Possible application: Nissan X-Trail Nissan A32 V6 Nissan A33 V6 Characteristics: part type - mechanical internal control valve for air conditioning compressor; for Calsonic CSV717, CWE615, CWV616 and CWV618 compressors; without electrical connector; O-rings are installed on the valve body; selection by compressor type and standard valve design. Advantages: allows you to replace a faulty internal valve separately from the compressor; Suitable for repair of compatible Calsonic compressors; there is no need to replace the compressor assembly if its other elements are in good condition. Important! Before ordering, check the markings of the installed compressor and compare the standard valve with the product photos. It is necessary to check the body shape, length, location of the O-rings and the design of the working part. Selection based only on car model does not guarantee compatibility. FAQ Is this a mechanical valve or a solenoid? This is a mechanical control valve without electrical control or connector. What compressors is it designed for? For selected Calsonic CSV717, CWE615, CWV616 and CWV618 compressors with corresponding control valve design. Is the valve suitable for Nissan X-Trail? Nissan X-Trail is listed among the applications, but before ordering it is necessary to check the model of the compressor installed and valve design. Is it possible to select a valve only according to the car model? No. It is necessary to check the type of compressor and compare the standard valve with the product photos. Does the compressor assembly need to be replaced? If it is the control valve that is faulty, but the rest of the compressor elements are working properly, the valve can be replaced separately.
