OPERATING AND
MAINTENANCE
SERIES 2023 NO-FREEZE CONTROL VALVE PREVENTIVE MAINTENANCE 1.
Seat - Check every six months if in normal service, i.e., no sander abrasive sand low pressure drop. If in severe service, i.e., high pressure drop and sanding condition, check every sixty days.
2.
Valve Plug - Same as number one.
3.
Valve Stem 0-Ring - Check for wear every year.
4.
Actuator - Check diaphragm once a year.
5.
General Maintenance - When Diassembling any portion of valve always check 0-ring for damage or wear before reassemble. Body - Under normal conditions body should last years. However, under severe conditions, i.e., corrosion, sand and high pressure drop, valve life could be numbered in days only. Inspect the body every time the actuator is removed.
APPLICATION The series 2023 is specially designed as a high pressure reverse seating dump valve for separate and other process vessels. The body screws directly into the vessel connection. This places the inner valve inside the vessel which allows any warm fluid present to retard freezing inside the valve body.
Caution: Before disassembly or maintenance, all pressures in this device must be relieved. Failure to relieve pressures may result in personal injury or device damage. The resulting uncontrolled venting or spilling of line fluids may cause personal injury, loss of process control or environmental contamination.
