PDF12-00 reverse regulating hydraulic brake valve

PDF12-00 reverse regulating hydraulic brake valve The valve, which adopts principles of direct acting three-way decompression valve, is used for the oil return brake system (oil cut-off brake) to realizes parking braking by the spring-brake/hydraulic-release brake. Reverse regulation means that braking is generated by reducing the preset pressure, which must be higher than the pressure required for the full release of the brake. The brake pressure is inversely proportional to the stroke of the operating control element or the stroke angle of the pedal, and the operating force is directly proportional to the stroke of the actuator. Technical parameter Max. pressure at port P: 20MPa Max. pressure at port A: 15MPa Return oil pressure: ≤0.5MPa Viscosity range: 10-380 mm2/s Oil temperature range: -20℃—100℃ Oil cleanliness: The solid particle pollution level of oil and system shall be less than GB/T…
