Pressure sequence valves DA700
Pressure-reducing valves from the DM700 series are leak-proof and suitable for pressures of up to 700 bar and flow rates up to 25 l/min.
- Max. operating pressure: 700 bar
- Max. flow rate: 25 l/min
- Size: Size 6 to DIN 24340 / ISO 4401 / CETOP RP 121 H
Features
Directly controlled, seat-tight, pressure adjustment possible over the entire pressure range, as a "standalone" valve or in valve linkage with sub-bases (AP700 and RP700)
Benefits
Seat-tight function with standardised NG6 connection surface to DIN 24340 / ISO 4401 / CETOP RP 121 H, high corrosion resistance, long service life, shut-off pressure can be limited to max. 350 bar using lock nuts, adjustable under pressure, well suited for mineral oil
Industries & Applications
The valve is used in two-circuit systems with a low-pressure (LP) pump and a high-pressure (HP) pump supplying the same consumer. The valve is used to switch the flow of the low-pressure pump independently of pressure. Before switching, both the LP and the HP pump supply the consumer.
Mounting
Seat design, as an intermediate plate valve, mounting on individual sub-bases as a "standalone" valve or in valve linkage with sub-bases (see technical data sheets AP700 and RP700), the shut-off pressure is set continuously via the adjusting screw, with rotary handle for setting the shut-off pressure, the set maximum pressure is fixed with a lock nut, with guided closing element
