Expansion valve (SV)
Brief description and function:
SV are beeing used to simple contol of hydromotor speed and to restrict flow at uneven load, ifuneven spead is unimportant and in cases, where is necessary hydromotor sped dependable on load in one direction (hydraulic breaking of heavy loads).
The throtting valve (pict.1) consists from the body (1), which together with anut (2) create throtting cross-section of the valve (b). The body is through, closed in one direction B - A by one-way valve (3). In this case, flow runs to the throtting cross-section (b) through holes (a). In the direction A - B is the valve through according to characteritc on the pict.2.
