Analysis of the pressure limiting valve and its failure

The pressure limiting valve is also called a check valve, a check valve, a pressure relief valve, and a pressure control valve. In motor vehicles, there are four types of pressure limiting valves, one is the pressure limiting valve 095420-0260 of the fuel system; the other is the pressure limiting valve of the lubrication system, […]

Do you know about UPS?

The Unit Pump Systems(UPS)  is a high-pressure fuel-injection system specially designed for commercial vehicles. Series production of the system at Bosch commenced in 1995. As with the Unit Injector System, each engine cylinder has a single-cylinder pump 0414401105 with integrated solenoid valve. This is connected to a conventional nozzle-holder combination via a short high-pressure line. […]

Why Control Valves used?

What is a Control Valve? Control valves automatically regulate pressure and/or flow rate, and are available for any pressure. If different plant systems operate up to, and at pressure/temperature combinations that require Class 300 valves, sometimes (where the design permits), all control valves 9308-618C chosen will be Class 300 for interchange-ability. However, if none of […]

Diagnosing Common Rail Diesel Faults – the Suction Control Valve

The suction control valve 04226-0L010 plays a critical role in the common rail diesel injection system, and is also one of the “usual suspects” in common rail diesel faults. For the average owner, looking to diagnose an issue with his vehicle, we are going to explain here the part the suction control valve 294009-1221 plays […]

Introduction to Pressure Relief valves

Pressure Relief Valves A pressure Relief Valve is a safety device designed to protect a pressurized vessel or system during an overpressure event. An overpressure event refers to any condition which would cause pressure in a vessel or system to increase beyond the specified design pressure or maximum allowable working pressure (MAWP). The primary purpose […]

How Do Diesel Fuel Shut-Off Solenoids Work?

A solenoid valve is an electromechanical valve controlled by an electric current. The electric current runs through a solenoid, which is a wire coil wrapped around a metallic core. A solenoid valve F00RJ00395 creates a controlled magnetic field when an electrical current is passed through it. This magnetic field affects the state of the solenoid […]
