Technical Descriptions:
Construction
The construction of steel gate valves of MSA corresponds to API 600 and BS 1414. Gate valves are yoke, flange or welded with unnarrow flow rate and with flexible or fixed wedge. Bodies, covers and yokes are cast. Wedges could be forged or cast. All wedges are guided. Sealing seats are bolted or welded into the body. Overlays in seats depends on Trim. Valves have rising non-rotative spindle and bolted joint of body-cover. Standard spindle threads are ACME2G-LH.
Operation with a handwheel. On the basis of mutual agreement, the gate valves can be operated by angle transmission, electric actuator or pneumatic actuator. For easier control the gate valve with larger diameters are equipped with bearings. Sealing material is pressed rings from expanded graphite and graphite plaited rings. The properties of gate valve packing meet the requirements of the directive Clean Air Act, Amendment from 1990. The gate valves can be also equipped with: drainage, venting, relief from inter-space and bypasses, on the special customer´s request.
