Abstract

The equipment includes a valve body and a first connection with a second connection connected to the valve body behind the front panel or bulkhead. A third connection extends through the panel; a flow control member operates from the front of the panel and comprises a tube mounted for sliding reciprocal axial movements within the valve body between two positions in the first of which the first connection is connected to the second connection via valve body, while the third connection is sealed off. In the second, the first connection is connected to the third connection via valve body while the second connection is sealed off.
