ンバルブを提供することにある。However, since the conventional valve has a structure in which the flanges on both the left and right sides are attached to the pipe, there is a problem that complicated work is required at the time of attachment and maintenance. Further, since the conventional valve has a structure in which it is mounted on a piping system, there is a problem that pipes are complicated in a plant handling a large number of fluids. Further, since the pipe and the valve each require a common flange, there is a problem that their shapes and sizes are limited. In addition, rubber cannot be used for the seal part for valves that open and close high-temperature, high-pressure steam, gas, etc., and a special metal seal is used, which complicates the seal structure and mounting structure. there were. SUMMARY OF THE INVENTION The present invention has been made to solve such a conventional problem, and an object of the present invention is to collect an installation port to a pipe on one side, thereby facilitating the installation, and further providing a clearance in a valve chamber. Another object of the present invention is to provide a normal-temperature, low-pressure fluid piston valve that uses a rubber seal to ensure airtightness.
