The valve operates automatically, allowing fluid to flow in one direction and closing to stop backflow when the flow reverses. With a pressure rating of PN40, this check valve is ideal for systems that operate at pressures up to 40 bar (580 psi), ensuring efficient flow control and protection of equipment. The compact body and streamlined flow path reduce pressure loss and make installation simple and cost-effective.
