This datasheet provides technical specifications, pressure ranges, materials, and interface details for Perfect fluid equipment accessories.
The document describes a range of back‑pressure valves and related accessories for electromagnetic metering pumps. It lists model numbers, pressure settings, material construction, seal types, thread standards and dimensions, and explains the operating principle of the spring‑loaded valve.
It also covers an electronic stroke regulator that can adjust pump stroke length manually or automatically via external signals. Technical parameters such as rated voltage, power consumption, control signal type, output accuracy, speed, IP rating and operating temperature are provided. This manual is written in Chinese.
| Back pressure range | 0 bar~5 bar |
|---|---|
| Safety valve pressure | 0 bar~18 bar |
| Body material | PVDF |
| Seal material | FPM / EPDM |
| Rated voltage | 100‑250 Vac |
| Control signal | 4‑20 mA current |
| Output accuracy | 0.06 mm |
| Maximum speed | 1 mm/s |
| IP rating | IP66 |
| Operating temperature | 0‑40 °C |
It uses an internal spring; when system pressure is below the set pressure the diaphragm blocks the line, and when pressure exceeds the set point the diaphragm compresses and opens the flow.
The regulator has an IP66 protection rating.
Set the back‑pressure knob to at least 1.5 bar.
