Minimum open pressure: 30-40mbar
Nominal pressure (working pressure): 0-16bar (0-232Psi), vacuum as low as -0.9bar optional.
Outside temperature (environment): -10℃~ 80℃.
Applicable media: water, neutral gas or liquid, alcohol, oil, fuel, steam, organic solvents, acid-base solutions, etc.
Medium temperature: -10℃- 180℃ (PTFE normal temperature type)
25℃- 220℃ (PTFE high temperature type)
Maximum viscosity: 600cst (mm²/s)
Valve leakage class: DIN EN 12266 Class A
Function Principle：
Medium enters the valve body through the inlet, pushing the valve stem and core upward to open the valve.
When the medium begins to flow back from the outlet, the spring force combined with the pressure from the
medium itself pushes the stem and core downward, thereby closing the valve.
