Return error: no locator is less than 3% of the full stroke (LHA1 is less than 5% of the full stroke).
The locator is less than 1% of the full stroke.
Basic error: no positioner is less than 5% of the total stroke.
The positioner is less than 1% of the full stroke (LHA1 band positioner is + 2%).
Note: Standard V PTFE packing is adopted.
The adjustable range is 50: 1 (0.25 Cv or less than 14), 30: 1 (Cv < 0.16).
0 Cv value and stroke
Note: symbol 0, Delta and V indicate the range of valves.
The symbol delta indicates the flow characteristics of valves accord with IEC534-1-1976 standard.
Typical flow characteristic curves
Note: it is recommended to use 9Cr18 hardened stainless steel when the temperature of cavitation, flash or water exceeds 100 C.
0 Cavitation, flash, oil prohibition and control valves which are often closed, regardless of the operating temperature and pressure, it is recommended to surfacing Stellay alloy.
If Cv is less than 0.16, all the spool shall be welded or welded with 9Cr18 hardened stainless steel.
Allowable pressure difference
I. plunger spool, metal valve seat (%CF, LCF)
A. gas shut valve
B. gas open valve
Note: The maximum allowable pressure difference shall not exceed the maximum working pressure specified in ANSI B16.34-1981 or JIS B2201-1984 standards.
The upper number in the same cell indicates the allowable differential pressure when the valve is fully open and the lower number indicates the allowable differential pressure when the valve is fully closed.
With * allowable pressure difference, the allowable pressure difference can only be 3 MPa when the valve controls the liquid. If the allowable pressure difference exceeds 3 MPa, please select ZHLC control valve.
