The pressure relief valve of series 485 with DN10 connection is designed for application in hydraulic legs of powered roof supports. The valve is intended to protect the leg against excessive pressure increase in the under-piston area. The operation principle of the pressure relief valve is based on the classic design of the piston with rows of holes, slidably mounted in the connection, with the pressure setpoint adjustment by means of a helical spring. The working medium flows out to the environment. The valve can be installed directly in the under-piston pipe of the leg.

The valve can operate with using HFA fire-resistant fluids (oil-in-water emulsions) with a concentrate content of 0.5–3%, based on mineral and synthetic oils compliant with the PN-C-96047 standard. If other operating fluids (mediums) have to be used, it is required to valve manufacturer.
