Componenti Idraulici

DESCRIPTION
Pilot operated pressure relief valve in screw-in cartridge construction for cavity according to ISO 7789. High flow capacity, very sensitively adjustable. If the pressure in P (1) exceeds the adjusted value of the valve, the excessive pressure is drained to T (2). Rapid switching with low hysteresis and excellent stability over the whole flow range. The small clearance of the hardened spool ensures a low leakage volume flow.

BSSPM18-315 (Part number 593.1014)

FUNCTION
When the set operating pressure is reached, the poppet spool opens and connects the protected line with the return line to the tank. By means of the adjusting mechanism the poppet spool is pressed onto a hardened seat which is pressed into the lower cartridge opening by a helical spring. Thanks to the poppet/spool principle and the direct operation, these pressure reliefe valves are rapid acting and free fo leakage oil. Therefore they are suitable wherever no leakage must occur in the system and where short opening times are demanded.

FUNCTION
When the operating pressure set by the proportional solenoid is reached, the main spool opens and connects the protected line with thereturn line to the tank. The back pressure in T(2) influences the pressure in P (1). This pilotoperated proportional pressure relief valve canbe adjusted very sensitively and is suitable forlarge volume flows and high pressures. To control the valve, Wandfluh proportional amplifiersare available (see register 1.13).

APPLICATION
The electrical remote control in conjunction with process controls allows economical solutions with repeatable processes. By means of the inverse function, the maximum system pressure is maintained if the electrical valve control falls out (safety function). The screw-in cartridge is perfectly suitable for installation in control blocks and is installed in sandwich- (vertical stacked systems) and in flange plates (corresponding data sheets in this register). For machining the cartridge cavity in steel and aluminum blocks, cavity tools are available (hire or purchase). Please refer to the data sheets in register 2.13.

BDBSA06-B-350-y-G12/L15-Z604 VALVOLA PROPORZIONALE CETOP 03 ATEX  (611.3286)

FUNCTION
By adjusting the electric current to the proportional solenoid the operating pressure in hydraulic systems is limited by reliefing the fluid from the protected lines P, A, B or A and B to the return / tank line T. Back pressure in T influences the pressure in the reliefed pressure lines. This proportional pressure relief valves are adjustable very sensitivly. To control the valve proportional amplifiers are available from Wandfluh (see register 1.13).

APPLICATION
These valves are suitable for applications in explosion-hazard areas, open cast and also in mines. The electrical remote control in conjunction with process controls allows economical solutions with repeatable processes. The crew-in cartridge is perfectly suitable for installation in control blocks and is installed in sandwich- (vertical stacked systems) and in flange plates (corresponding data sheets in this register). For machining the cartridge cavity in steel and aluminum blocks, cavity tools are available (hire
or purchase). Please refer to the data sheets in register 2.13.
