PAMEL PZN1 – stainless steel solenoid valve 1/4″
Leave feedback on the product
The PAMEL PZN1 is a direct-acting 1/4″ stainless steel solenoid valve that requires no minimum pressure or differential pressure. It also operates by gravity and at very low pressure. Its operating temperature range is -10…150°C, operating pressure is 0–10 bar, and flow coefficient Cv is 0,23 (approximately 0,75 l/min). Coil options include 12 V and 230 V.

PZN1 – a stainless steel valve that also works without pressure
The PZN1 does not require a pressure difference to open or close. This makes it suitable for gravity systems, dosing systems, process equipment, and installations where a typical pressure-dependent diaphragm valve does not function properly.

The most important features
No minimum pressure
The valve is direct acting, so it can also operate under gravity and very low pressures.
Stainless steel construction
The body and internal components are made of stainless steel, which increases durability in demanding installations.
For small flows
Cv = 0,23 corresponds to an approximate flow rate of approximately 0,75 l/min, depending on the medium and pressure.
The most important information
- 1/4″ internal connection thread (GW)
- working pressure 0–10 bar

- direct acting – no minimum pressure required
- stainless steel body and internal parts
- DIN plug with LED indication
- coil voltage variants selected at purchase
- Applications: distillates, laboratories, small circuits, dosing and automatic shut-off of liquids
