with bellow sealing globe valves are used for proper tightness and the more accurate flow control in both thermal oil and hot water systems. for thermal oil applications, the standard is to fit bellow sealing in addition to the regular stuffing box. sizes: nd - pressure classes: pn - material nodular...
: when installed in-line, it sustains minimum pre-set, upstream (back) pressure regardless of fluctuating demand or varying downstream pressure. when installed as a circulation valve, it relives excessive line-pressure that is above maximum pre-set. the valve opens and shuts-off in response to an...
at the bottom of the borehole, eliminating production constraints due to liquid loading. in oil wells, whc units reduce the pressure on pipes and largely preclude the development of backpressure that could impair production. problems with air entrapment no longer occur, and the pump's delivery rate...
data on the lubrication process is monitored in real time. deviations from preset values for a given operating condition are analyzed, resulting in an adjustment of the lubrication rate if required. hydraulic unit: a centralized hydraulic pump keeps the oil in the common rail under constant high pressure...
