Valve Operation

  • For system applications that require large discharge releasing capacities, GE’s 13900 valve series provides very reliable working economy and a simple, efficient valve design. In addition, its valve configuration simplifies valve installation and in-line valve maintenance.

  • Greater Total System Efficiency. The main valve can handle extremely large relieving capacities, in excess of 3 million pounds of steam per hour 1,360,777 kg/hr). It has a seven-to-one discharge capacity over a “T” type orifice, and a two-toone discharge capacity over a “W” type orifice.

  • Improved Design. The total valve external configuration is considerably smaller in size, and the valve is lighter in weight than a comparable spring-loaded valve. Because of these features, less space is required for valve installation.
    A simple, efficient, and reliable direct acting valve design with few components eliminates the need for excessive spare parts inventory and reduces maintenance time.

  • Easy Installation and Maintenance. Valve configuration is considerably smaller in size and lighter in weight than a comparable spring-loaded valve. This simplifies installation, field handling, testing, and valve maintenance.
    Valve maintenance is relatively simple and straightforward. The simple valve design means fewer parts, so less can go wrong, malfunctions can be readily diagnosed, and maintenance cost and process downtime can be very limited.
    To simplify valve maintenance, all main valve components are removable through the top bonnet of the valve. The pilot valve can be field tested and repaired without breaking inlet and outlet piping connections on the main valve. The pilot valve opening and closing is easily adjusted on a small test facility.
