Typical Failures of Pilot Relief Valve
With the development of construction machinery hydraulic system towards the direction of medium, high and ultra-high pressure, pilot relief valve is widely used in the oil control pipelines of construction machinery hydraulic systems. In practice, in order to maximize its efficacy and protect the control system, accurate and timely diagnosis and troubleshooting of sanitary relief valve […]

What are the different types of hydraulic pressure relief valves? There are many kinds of sanitary pressure relief valves, they can be divided into two general categories: direct-action type and indirect-action type. The direct-action type uses the energy of the medium itself to control the required pressure. The Indirect-action type uses external power, such as […]

Pressure Relief Valve Mechanism: There are many types of sanitary pressure relief valves. Piston type and spring film type are the main two types. Piston type pressure relief valve is a type of valve that uses a piston for pressure relief. Spring film-type pressure relief valve relies on spring and film for pressure balance. The […]

What is the Mechanism of Oxygen Pressure Relief Valve? The high-pressure chamber of the oxygen pressure relief valve is connected to the steel cylinder. The low-pressure chamber is for gas emission and also has access to the system. The indication of the high-pressure gauge is the pressure of the stored gas in the steel cylinder. […]

How do pilot-operated relief sanitary relief valves work? The pressure of a pilot-operated sanitary relief valve is provided on the upstream side (the system being protected) at the dome often by a small pilot tube. The downstream side is the pipe or open-air where the PORV directs its exhaust. The outlet pipe is usually larger […]
