The brass needle shut-off valve with manometer connection is a reliable solution designed for hydraulic systems, ensuring safe and efficient isolation of the manometer from the installation. By protecting the measuring device against overloads and sudden pressure surges during system start-up, it significantly extends its service life and guarantees accurate readings. The valve also enables quick and convenient replacement of the manometer without interrupting the operation of the entire system. Available in two functional versions – straight in-line (FPE) and angular 90° (FPEA) – it offers flexibility of installation to suit diverse technical requirements. Its robust construction combines a nickel-plated brass body, a durable carbon steel needle, galvanized steel connection nut, and an ergonomic plastic knob, ensuring both strength and ease of use. The integrated thread under the knob allows for simple panel mounting, making it highly practical in professional applications. Equipped with NBR sealing for reliable tightness, the valve operates within a wide temperature range from -20°C to +100°C. With connections GW 1/4″ BSP (manometric) and GZ 1/4″ BSPT, it guarantees compatibility with standard hydraulic systems, making it an essential component for precise pressure monitoring and long-term system protection.
