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.

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).

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.

BVPSA10-P-350-G24/WD-HB4,5 VALVOLA (611.4027)

Product info
Product name: B_A10
Nominal size: NG10

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.

BVSPM33-160 Pressure relief cartridge pilot operated M33X2 (593.8007)

DESCRIPTION
Pilot operated pressure relief valve as screwin cartridge with a thread M33x2 and cavity according to ISO draft 7789. The valve is available in two different setting versions: Key setting "S" and turning knob setting "D". Key adjustment "S" is also available with cover, see data sheet 2.0-50. 2 standard pressure levels are available: 160 and 350 bar. The cartridge body made of steel is galvanized and therefore rust-protected.
