Steel Wedge Gate Valve with Expanding Spindle for Pipeline Applications

The cast steel wedge gate valves (hereinafter referred to as gate valves) with sliding spindle belong to pipeline valves. Gate valves are designed for use as a shut-off device on process pipelines, tanks and other equipment of field and gas gathering points, gas processing plants, underground gas storage facilities, linear part of main gas pipelines, process pipework of compressor, booster, gas distribution and gas metering stations of PJSC Gazprom. Gate valves by type of control can be manually controlled by handwheel, manually controlled by gearbox, controlled by various types of actuators, such as: electric drive, pneumatic drive, hydraulic drive and other types of actuators. Gate valves by type of connection to the pipeline or equipment are divided into flanged and welded. Gate valves must ensure tightness in the shut-off element of a certain class from A to E, depending on the object or working medium moved through the pipeline. Materials, from k...
