Safety valves 4000 Series
Available with GAS and NPT threaded connections or flanged in accordance with ASME B 16.5 or EN standard with sizes from ½ “to 2”, and set pressure up to 400 bar (1/2” valves).
The theoretical maximum capacity, for triplex pumps, arrives to 21 m³ / h ( 2 “valves).
The valves are manufactured in stainless steel, as standard material, but are also frequently produced in
plastic materials (PVC, C-PVC, PTFE, PVDF) and in super-alloys for maximum reliability with particularly aggressive fluids. The valve can be equipped with balancing/insulating bellows, and heating jacket in the case of backpressure and fluids that solidify at room temperature.
The version with a balancing piston and integral flanges is suitable to work correctly in the presence of high back pressures.
The 4000 series is supplied with PED certification and CE marking in compliance with Directive 2014/68/EU.
