Abstract
The present invention is a novel pressure relief valve (PRV) design that is used in closed circuit systems containing pressurized fluid, preventing dirt accumulation during discharge and preventing liquid leakage. A continuous clean flow is provided in the discharge area and system performance is increased with the help of the change in the membrane (6) design. The invention offers a low-cost, long-lasting and durable solution by being produced with environmentally friendly thermoplastic materials. The membrane (6) design ensures cleanliness in the discharge area and improves system performance, regardless of the orientation in which it is installed. The novel design is produced with environmentally friendly thermoplastic materials, providing a low-cost and durable solution.
