Packing leakage could result in personal injury. Valve packing is tightened prior to
shipping but may require adjustment to meet specific service conditions. If the fluid
is hazardous or toxic then proper protection is required before the removal of the
valve.
Always be sure that the valve is de-pressurised and isolated prior to performing
any maintenance work. Do not attempt to repair valve in-line if volatile, dangerous,
hazardous or flammable service.
Personal injury may result from sudden release of any process pressure. APV
recommends the use of protective clothing, gloves and eye wear when performing
any installation or maintenance.
Isolate the valve from the system and relieve pressure prior to performing
maintenance.
Disconnect any operating lines providing air pressure, control signals or electrical
power to actuators.
