Thermostat & Minimum Pressure Valve Kit 2901353100 – 8000H STD

The THERM. & MPV KIT 8000H STD, part number 2901353100, is a maintenance kit intended for oil-injected rotary screw compressors. It is associated with the compressor's thermostatic control system and Minimum Pressure Valve (MPV), two functional elements that contribute to the correct operation of the lubrication, cooling and air-oil separation systems.

Designed for scheduled maintenance, the kit supports the reliable operation of industrial compressed air equipment, helping maintain appropriate operating conditions and reduce the risk of performance issues associated with worn or deteriorated components.
Main functions and applications
1. Oil temperature regulation

The thermostatic system helps regulate oil flow according to the compressor's operating temperature. In systems equipped with a thermostatic valve, the device controls the routing of oil through the cooling circuit, supporting the achievement and maintenance of a suitable operating temperature.

Proper thermostatic operation helps maintain appropriate lubrication conditions and contributes to protecting internal compressor components from the effects of unsuitable oil temperatures. The exact operating principle depends on the compressor design and the configuration of its oil circuit.

2. Minimum Pressure Valve (MPV) operation

The Minimum Pressure Valve is installed in the air-oil circuit of compatible compressor designs. Its primary function is to help maintain a minimum internal pressure during startup and operation.

Maintaining the required pressure supports the proper operation of the air-oil separation system and helps regulate the delivery of compressed air to the downstream network. Depending on the valve design, it also helps prevent reverse airflow when operating conditions require it.

Correct MPV operation is important for maintaining stable compressor performance and ensuring that the internal pressure-control and air delivery systems operate as intended.

3. Scheduled preventive maintenance

The designation 8000H STD identifies a standard kit associated with an 8,000-hour maintenance interval. The actual replacement schedule must be confirmed against the compressor manufacturer's maintenance documentation, as service intervals may vary according to the specific model, operating conditions and maintenance requirements.

Replacing the relevant components as part of scheduled servicing helps address normal wear and supports the continued reliability of the compressor. The kit is suitable for planned maintenance procedures when specified for the equipment concerned.

4. Operational reliability and compressed air performance

The correct operation of the thermostatic control system and minimum pressure valve contributes to stable compressor operating conditions. Maintaining these components according to the manufacturer's recommendations can help reduce the risk of operational irregularities, unexpected downtime and corrective maintenance.

This kit is intended for industrial maintenance applications where the servicing or replacement of thermostatic and minimum pressure control components is required.
