Parker D1VW Directional Valves
The D1VW series covers direct-operated directional spool valves with solenoid actuation. Selection runs on four axes: spool symbol, coil voltage, seal material and spring return. NBR and FPM differ in media and temperature resistance, not in the mounting pattern, which is why a mix-up only shows up in service.
Valve failed or system down?
Replacement and repair of valves, accumulators and cylinders: own workshop, own technicians, across all manufacturers.
FAQ
Frequently Asked Questions
NBR or FPM: which seal do I need?
NBR is the standard seal for mineral oil. Choose FPM for higher temperatures and for media that attack NBR, such as certain fire-resistant fluids. The seal material is listed in the technical data of every article.
How do I find a replacement for an installed valve?
Take the complete type designation from the nameplate, not just its opening block. Two valves from the same series can differ in spool symbol, voltage and seal, and are then not interchangeable. With the full designation, search leads straight to the article.
Replace or repair?
For valves of this size, replacement is usually the faster and more economical route. For larger valves, manifolds and power units, the PTS workshop assesses whether a repair makes sense and states effort and date up front.

Counterbalance Valves
During lowering the counterbalance valve does the braking work, so the lowering speed is set by the control system and not by the load. If that braking action is missing or the valve is wrongly sized, the load sags on start-up and the lowering motion turns jerky.
Bladder Accumulators
A bladder accumulator is a hydropneumatic pressure vessel: inside the steel shell, an elastic bladder separates the nitrogen-precharged gas side from the oil side. When system pressure rises the accumulator takes in oil, and when it falls it gives the oil back. That is how you store energy, damp pulsations, absorb pressure surges or compensate for leakage losses. Four figures narrow the selection: nominal volume, permissible working pressure, port and the elastomer of the bladder, which has to suit the medium and the temperature. Typical nominal volumes range from about 4 to 50 litres with pressure ratings up to 350 bar. PTS supplies bladder accumulators from Parker Olaer, HYDAC and Bosch Rexroth from stock, plus mounting clamps, seal kits and replacement bladders, so an accumulator can be repaired instead of replaced outright.
Heavy-Duty Cylinders
PTS supplies hydraulic heavy-duty cylinders from stock at 50 to 150 tonnes of nominal force, with strokes of 50 to 300 mm, single- and double-acting in a compact design. Forces and strokes outside that range are available as further versions on request.
Flange Spreaders
Flange spreaders act on a seized flange joint. It is opened for maintenance or assembly work. The gap has to open evenly, or the sealing face is damaged. How much spreading force is needed depends on the size of the flange and how tightly it is seized.
