Lift - lower block (FLLB)
Lift lower blocks are compact assemblies used to control single acting cylinders for lifting & lowering functions. When connected to a single acting cylinder, the block facilitates lifting and only works as a pressure limiting (relief) valve to ensure safety of the system. Once lifted, the check valve and poppet valve support in position holding including intermediate positions. When lowering is required, the poppet valve facilitates lowering through gravity. The lowering speed may be adjusted using the adjustable throttle valve.
The valve assembly is also available in 15 and 30LPM versions and is rated for maximum pressure of 150bar. The valve is also available with a manual knob type (spring return) or lever type actuation for lowering control. The solenoid version has a manual over-ride feature as standard. The solenoid operated versions have 12 and 24V DC coil or 220V AC coil options.
These valve assemblies are commonly used in service lifts, material handling, warehousing equipment, construction equipment and residential lifts.
