KSHN type kelly valves for pump-compressor pipes with tubing thread

KSHN kelly valve is designed for automatic overlap and pressurization of the drilling tool tube channel in drilling oil and gas wells, and also in maintenance and emergency works. TS 3661-001-79560377-2009

The valve structure allows maintaining pressure in any direction. The valve may be installed above and under the work tube. The platelike spring ring provides reliable sealing. The valve is designed for a standard operating pressure of 70 MPa, but upon customer's request the structures may be produced designed for higher pressure.
