Product Description
The PBFBLAN Relief valve delivers reliable overpressure protection in a space‑saving cartridge format. Its poppet and seat are precision‑matched to achieve near‑zero leakage when closed, which is critical for load‑holding applications. The adjustment mechanism uses a fine‑pitch screw for accurate setting, and a locknut secures the chosen pressure against vibration. The valve is designed for use with oil‑based fluids and can withstand severe shock loads common in off‑road machinery. Maximum operating pressure is 350 bar, and flow capacity reaches up to 60 L/min, making it suitable for auxiliary circuits and pilot lines. The exterior is hardened to resist wear from contaminants, and the internal parts are heat‑treated for extended durability. Installation is straightforward with standard O‑ring seals and recommended torque values. Applications include boom cyLinders, steering systems, and attachment hydraulics where space is at a premium. The PBFBLAN also supports optional manual override for emergency release.
