Low Noise Type Solenoid Controlled Relief Valves

Transcription

1 he low-noise solenoid controlled relief valve is a combination of a low-noise type pilot operated relief valve and a solenoid operated directional valve. It is used for no-load pump operation by using electric signals or, together with a remote control relief valve, for two or three pressure control of the hydraulic system. pecifications Max.

Use high venting pressure types to reduce response time from unloading to onloading. 3. he vent types are the same as for the conventional type solenoid controlled relief valves. For the details of the vent types, see page.. he coil codes are the same as for solenoid operated directional valve DG-0 valve. ee the solenoid ratings on page 35. he coil type numbers in the shaded column are handled as optional extras.

2 PREURE ONRO Option Models with vent restrictor he type with a vent restrictor has a vent restrictor in vent types B3A and B3B added between a relief valve and a solenoid operated directional valve. It prevents shock to the main circuit by gradually lowering the venting pressure in the shift from the setting pressure to unloading. Unloading pressures are the same as without a vent restrictor.

In addition, if the internal volume of the vent line is too large, chattering is likely to occur. hus, as far as possible reduce the inside diametre and the length of the pipe. o adjust the pressure, loosen the lock nut and turn the handle slowly clockwise for higher pressures or anti-clockwise for lower pressures. After adjustments, do not forget to tighten the lock nut. Piping of the tank line should not be connected to any tank line of the other valves, but connected directly to the reservoir. Pressure is limited by collars fitted. If a working pressure cannot be attained, remove some collars. One collar is equivalent to 0 MPa (50 PI). a small flow, the setting pressure may be unstable. Use models numbered and with a flow rate above 5 /min (.3 U.. GPM) and model 0 with 8 /min (. U.. GPM). Interchangeability in Installation between Old and New Design. Design 53 valve is one on which DG-0, design 70 is mounted as a pilot valve. It is interchangeable with old design (design 5) with respect to specifications, exterior shape and mounting dimensions. 3
