Product Description
- The DRV 250 is an unrelieved, diaphragm-controlled pressure reducing valve for precise regulation of low back pressures(0.2–2 bar) at inlet pressures of up to 25 bar – ideal for compressed air, nitrogen and neutral fluids at low flow rates.
- The DRV 250 is an unrelieved, diaphragm-controlled single-seat pressure reducing valve for the continuous regulation of low downstream pressures from 0.2 to 2 bar at a maximum upstream pressure of 25 bar.
- It has a high reduction ratio of 20:1, internal thread according to ISO 228, and pressure gauge connections G 1/4" on both sides for the back pressure.
- The valve is temperature-resistant up to 100 °C, has a robust red brass housing and is particularly suitable for use in compressed air and nitrogen systems with low flow rates.
