Item # 6012-2-UT, 2" Class 600 Gate Valve

Cast carbon steel gate valves 600 pound pressure class with bolted bonnet, outside screw and yoke, FLEX-WEDGE and seal welded seat rings manufactures in accordance with API 600.

Application
These gate valves are used in pipelines and in facilities for water, steam, non-aggressive gases, naphtha, naphtha derivatives and in other power and process installations, in operating conditions up to 800°F (427°C), In accordance with Table No. 1 Data included in this Table meet the pressure- temperature ratings of ANSI B16.34

Technical Data
The basic dimensions of the gate valves are in accordance with Table No. 4. Face to face dimensions of the gate valves are in accordance with ANSI B16.10. The pipe flanges are regularly furnished faced and drilled with 0.25" (6.4mm) raised faces, in accordance with ANSI B16.5 (See Note). The raised faces of the pipe flanges are machined in accordance with MSS SP-6. The wedges are or the single wedge flexible type providing greater sealing capability and lower torque requirements. Operation is performed by a non-rising handwheel; the closing direction is to the right. Upon request, gate valves are made with enclosed bevel gearing. For remote control, these valves can be equipped with electric or air motor operating units.

The wedges have accurate guide slots, assuring true alignment and providing full guidance during operation.

The seat rings are seal welded in the body and are made of carbon steel with hard faced seat surfaces. The seat faces on the wedges are made by welding on 13 CR Stainless Steel.

The gate valves are provided with a backseat bushing, in the bonnet, enabling the replacement of the stem packing when the valve is in the wide open position.
