Three-piece ball valves

Simple construction and operation, a small installation space compared to the other valves, fast opening and closing by rotating the handle in 90°, a circular cross section with a full or narrow passage, a very small hydraulic resistance because there is no turning of flow line of the fluid, baukasten principle of building - easy maintenance and reduced cost of stocking spare parts, various material combinations offer the possibility of wide area of application.

Two-piece ball valves

Two-piece ball valves with thread fit for nominal pressure PN 16, 25, 40 and 63, and at the request of the customer we produce PN 100 i 160 as well as Class 150, 300, 600, 800, 900, 1500. Operating temperature is limited by applying teflon (PTFE) as a sealing material up to max. 200°C. The area of application is very broad, so it includes their application and installation in the lines with non-aggressive and aggressive fluids in consultation with the manufacturer.

KVS - valve from 0.008 to 925 m3/h
Leakage max. 0.01%Kvs

 

Calculation of the Kv value of the valve is done according to DIN IEC 534. Questionnaire contains the parameters of the valve needed for calculation.

For a simplified calculation of control valves generally known formulas given in the table can be used.

Calculation of the Kv value

p1 Inlet pressure
p2 Outlet presure
H Stroke
Q Flow u m3/h
W Flow u Kg/m3
ρ Density Kg/m3
(Liquid)
ρ1 Inlet density Kg/m3
(For gas and steam)
t1 Inlet temperature °C

Kv formulas table

After the Kv value is calculated, the Kvs is chosen - value is in the valve characteristic diagrams (linear and straight percentage).

If the real parameters were used in calculation, in most cases will be ≈ 0,7 do 0,8 • Kvs.
