Two-port, two-way directional control valves for 160 litre/min systems offer the designer good flow characteristics, low internal leakage and relative insensitivity to fluid contamination.
Integrated Hydraulics has introduced two-port, two-way directional control valves for 160 litre/min systems.
Poppet type, solenoid operated directional control valves offer the designer good flow characteristics, low internal leakage and relative insensitivity to fluid contamination.
Spool type valves rely on the close fit of the spool and sleeve to limit leakage across the spool's lands when closed.
The poppet valve, however, uses a piston pressed against its seat by fluid pressure to prevent flow: with mating parts concentric and surface finish suitable, flow past the valve will be low, in this case less than five drops per minute at 210bar pressure differential.
This arrangement also provides better flow conditions when the valve is open, thereby reducing pressure losses.
When the valve is open, the flow washes over the poppet and seat removing any contamination that may be present, even the smallest particles of which can cause havoc in a hydraulic system.
They come in normally open and normally closed versions and they fit cavities common to a number of other manufacturers.
The solenoid operates a small pilot piston in the main poppet; this controls the pressure of fluid behind the main poppet and the balance of pressure forces moves the piston to the desired position.
This arrangement reduces the power required by the solenoid permitting high flow, high pressure applications.
There are 12 and 24V DC and 110 and 220V AC solenoids with various standard connectors.
The coil stem is sealed to prevent corrosion and the coils are the same as those used on other S5 series valves reducing spares inventory.
These cartridge valves can be fitted in standard line bodies or used with other valves required in a system, in hydraulic integrated circuits or manifold blocks.
If the latter option is used, the designer can reduce the number of joints in the system, reducing the possibility of oil leaks, and concentrate most or all of the valves into one self contained, pre-tested block to speed assembly and reduce space.
