Production Description:
API Power Station Gate Valve 6
Products design features
1Actuation modes: manual, electric, spur and bevel gear, pneumatic actuations, please make it clear at order.
2Weld-connected gate valve and stop valve are suitable for the pipeline of PN1 .6~32.OMpa, P54/100V~P57/170V, a working temperature 540(570 for P57/170V) in various systems of petroleum, chemical industry, steam power, hydraulic etc. to cut off and get through the medium. The suitable media are: water, steam, oil goods, acid media and so on.
3Conforms with the requirements of the domestic and foreign advanced standards. The middle cavity of the valve uses the pressure self-tightening sealing structure, the two ends of the branch pipe use welded structure and the welded groove can be connected per either the standard or the required one by users. Of a reliable seal, good performance and nice modeling.
4The sealing faces of both disc and seat ring are made by means of built-up welding with either iron-based alloy or Stellite Co-based carbide alloy upon different requirements, wearable, high temperature resisting, corrosion resisting, good friction resisting and long duration.
5The stem, after the modified and surface nitriding treatment, has a good friction and corrosion resistance and a back-seal structure to ensure the valve no leak outward from the stem when opened during running and able to replace the stem packing.
6 The valves with a large or a middle apertures can use the internal by-pass structure and be set with a rolling bearing and a thrust bearing, resulting in flexible open-close.
7The electric stop valve is fitted with SMC valve electric actuator, features a small casing, light weight, full functions and a nice outlook and can be used either with a program controlled computer or an electric actuator upon the user requirement.
