Common Applications:<\/strong><\/p>\n\u2022 Pumping systems and hydraulic power units.
\n\u2022 Accumulator protection.
\n\u2022 Industrial presses and heavy machinery.<\/p>\n
Maximize your system’s durability and safety with an expert in high-pressure hydraulics.<\/p>\n
Compact Line (High Pressure: 400 bar)<\/strong><\/p>\n\u2022 HG-G1\/4 (DN 6): The ideal solution for instrumentation and fine control systems. Supporting up to 400 bar of pressure, this compact valve ensures maximum safety in confined spaces without compromising sealing.
\n\u2022 HG-G3\/8 (DN 10): The perfect balance between size and performance. Designed for flow rates of up to 40 L\/min, it is widely used in pilot circuits and auxiliary systems that operate under high pressure of 400 bar. <\/p>\n
Intermediate Line (Medium\/High Pressure: 350 bar)<\/p>\n
\u2022 HG-G1\/2 (DN 12): One of the most versatile valves in the line. With a robust 30mm (hexagonal) body, it supports 350 bar and is the standard choice for industrial hydraulic units that require constant and safe flow.
\n\u2022 HG-G3\/4 (DN 16): Developed for systems that require greater fluid passage without loss of efficiency. Its 90mm length construction ensures durability in continuous operating cycles at 350 bar.
\n\u2022 HG-G1 (DN 20): Designed for high flow rates in main systems. With support for 350 bar, this valve combines a 46mm (hexagonal) structure with optimized internal passages to reduce fluid heating. <\/p>\n
\u2022 Large-Scale Industrial Line (250 bar)<\/p>\n
\u2022 HG-G1 1\/4 (DN 25): Ideal for high-capacity filtration and return systems. Supports operations up to 250 bar, offering a secure 1 1\/4″ connection for applications that move large volumes of oil.
\n\u2022 HG-G1 1\/2 (DN 30): Extreme robustness for the heavy sector. With a body diameter of 64.5mm, this 250 bar valve is essential in presses and mining machinery where retention failure is not an option.
\n\u2022 HG-G2 (DN 40): The largest model in the HG series, at 160mm in length. Perfect for large-scale hydraulic systems, it ensures full free flow and instantaneous blockage in 2-inch piping under 250 bar pressure. <\/p>\n
