The HF3P4SB1TBV2H03 hydraulic filter assembly belongs to the Vickers Hydraulic Accessories series and is produced by Vickers for use in automated fluid power circuits. The unit measures 293 mm (11.5 in) in overall length, which allows installation in medium-capacity return or pressure lines where space is limited. A ductile iron head provides a rigid mounting surface, while the carbon steel bowl forms a pressure-tight chamber for the element. Contamination control is handled by a 3 µm filter element that achieves a beta ratio of 1000, delivering high particle retention efficiency in cyclic duty. The valve configuration is non-bypass, so all oil is forced through the media until the element reaches the programmed restriction. To flag service needs, a differential indicator trips at 7.9 bar (115 psi). Structural safety of the element is maintained up to a collapse pressure of 207 bar (3000 psi), preventing media rupture during cold starts or flow surges.
The assembly supports continuous operation at 410 bar (6000 psi), and this same value defines its fatigue pressure capability for repetitive loading in high-pressure manifolds. Hydraulic flow up to 208 L/min (55 US gpm) can pass through the filter when the element length is size 2, ensuring adequate throughput for servo actuators and proportional valves. Connection to the circuit is made with an SAE-16 port using a 1.312-12 UN thread, simplifying integration with standard tube fittings. Viton-A seals are fitted to resist common petroleum and synthetic fluids while withstanding temperatures from −26 °C to 121 °C. The dry weight of 22.5 kg (49.5 lb) must be supported by the mounting brackets or manifold face to avoid stress on the piping. These characteristics define the operating envelope and confirm suitability for applications that demand reliable filtration under severe pressure, temperature, and flow conditions without relying on a bypass route.
