Manual Gate Valve
ANSI/ASME FLANGE GATE VALVE
The stainless steel flange gate valve drives the valve stem through a handwheel or actuator to move the gate vertically to control the flow of fluid. When the gate is fully raised, the fluid flows unimpeded; when the gate is fully lowered to the valve seat, the fluid is completely cut off. Its excellent corrosion resistance and sealing properties make it widely used in high temperature, high pressure and corrosive environments.
Description
Structural advantages and characteristics
- 1、Meets the domestic and foreign advanced standard requirement, the seal is reliable, the performance is fine, handsome appearance.
- 2、The damper plate, the valve seat packing surface is too vertical (stellite) with the iron-base alloy built-up welding or the department the cobalt base hard alloy built-up welding to become, wear-resisting, thermostable, anti-corrosive, the anti-abrasion performance is good, the service life is long.
- 3、Using wedge-type flexible gate structure, medium and large caliber set bearings, switches flexible, open and close easily.
- 4、Stem quenched and the nitrogen treatment, with good corrosion resistance, scratch resistance and wear resistance.
- 5、Can be used with a variety of standard pipe flanges and flange sealing surface types to meet various project needs and user requirements.
- 6、Valve body materials, variety, packing, gasket can be based on actual working conditions or the user requests a reasonable option,can be applied to all kinds of pressure, temperature and medium conditions.
