Abstract

A changeover valve system is provided that is adapted to be secured at one end to a riser from a pressurized piping system and at its opposite end to at least two pressure relieving devices. The changeover valve system includes a body and at least two elbows secured to the body to which are attached at least one of the pressure relieving devices. A
partially spherical changeover member is provided within the body having at least one inlet port adapted to communicate with the riser and at least one and preferably two outlet ports adapted to alternately communicate with either of the pressure relieving devices.
Transport means are provided for effecting rotation of the changeover member within the body to cause the changeover member to travel from one position wherein an outlet port is in communication with one of the pressure relieving devices to a second position wherein an outlet port is in communication with the other pressure relieving device.
Locking means are provided for securing the changeover means in either of these two positions. A cross drive member is further provided which includes a top portion having an upper tenon for engaging the means for rotating and a bottom portion having a lower tenon for engaging the changeover member. The longitudinal orientation of the upper tenon is offset by up to about 30 degrees from the perpendicular of the lower tenon.
