A new customer required a Parker Denison R5U (R5U12) relief valve, which was to be mounted directly onto a pump. The valve is now being delivered to the customer.
Cetop 03 Valves
These Cetop 03 directional control valves are designed for subplate mounting and have an industry-standard interface. Having solenoids with wet armatures also means an extremely safe construction that removes the need for a dynamic seal; the solenoid tube is screwed directly onto the valve casting whilst the coil is kept in position by a ring nut. The operation of the directional valve is electrical and the centring is achieved by calibrated length springs which, once the impulse is over, immediately reposition the spool in the neutral position. To improve the valve performance, different springs are used for each spool, while electrical controls are equipped with an emergency manual control inserted in the tube. The recommended fluids are hydraulic mineral based-oils in accordance with DIN 51524.
