OUNCES PRESSURE REGULATOR BACK PRESSURE TO ATMOSPHERE W/OUTSIDE SUPPLY

Transcription

1 OUNES PRESSURE REGULATOR BAK PRESSURE TO ATMOSPHERE W/OUTSIDE SUPPLY APPLIATIONS: Valve designed to regulate ounces ( oz to.5 psig) back pressure on a tank and vent to atmosphere when pressure exceeds set point. An outside supply of 0 psig is raised to operate motor valve. EATURES: Intermittent bleed pilot Soft seat for bubble tight shut-off High capacity (ull opening seat) External pilot isolating process stream from instrument supply gas PRESSURE RANGE: Upstream Pressure:.5 oz to.5 psig Optional springs provide a set point of: oz to 5 psig or psig to 0 psig APAITY: See Table of ontents Motor Valve Assembly Pilot Assembly Motor Valve Diaphragm Pressure Downstream Pressure Upstream Pressure Supply Pressure (outside source) Adjusting Screw OPERATION: This Regulator maintains a low pressure back pressure by relieving to a lower pressure or atmosphere. The pressure to operate the valve is an outside pressure source. The Regulator consists of a three-way pilot operating a motor valve. The only moving parts are the Pilot Assembly and the Motor Valve Stem Assembly (rosshatched). The three-way pilot action is due to the operation of the PILOT PLUG. The PILOT PLUG consists of two stainless balls rigidly connected. The upper PILOT PLUG seat is the Motor Valve Diaphragm Pressure vent (Yellow to Atmosphere). The lower PILOT PLUG seat is the Motor Valve Diaphragm Pressure inlet (Violet to Yellow). The Pilot Assembly actuates the PILOT PLUG. The force of the PILOT SPRING above the PILOT DIAPHRAGM acts against the Upstream Pressure (Red) below the PILOT DIAPHRAGM to determine the motion of the Pilot Assembly. Assume a desired Upstream Pressure (Red) greater than the current setting. The ADJUSTING SREW compresses the PILOT SPRING. The PILOT SPRING forces the Pilot Assembly downward. irst, the upper PILOT PLUG seat (Yellow to Atmosphere) closes, then the lower PILOT PLUG seat (Violet to Yellow) opens. Increased Motor Valve Diaphragm Pressure (Yellow) pushes the Motor Valve Stem Assembly downward and closes the motor valve. Assume the Upstream Pressure (Red) increases. The increased Upstream Pressure pushes the Pilot Assembly upward against the PILOT SPRING. This first, closes the lower PILOT PLUG seat (Violet to Yellow), then opens the upper PILOT PLUG seat (Yellow to Atmosphere). Motor Valve Diaphragm Pressure (Yellow) decreases, Upstream Pressure (Red) pushes the Motor Valve Diaphragm Assembly upward. The motor valve opens. This rapid but stable interaction of the Pilot Assembly and Motor Valve Diaphragm Assembly produce a true throttling action. Pilot Spring Pilot Diaphragm Pilot Plug Motor Valve Diaphragm Oil A:95.
