Forged Cryogenic Gate Valve

KOSEN Forged Steel Gate Valves are suitable for using on various kinds of pipeline cut off or connect the flowing of medium. By using different material, the valves could be suitable for medium such as water, steam, oil, nitric acid, acetic acid, oxidizing substance, carbamide and etc. Molded flexible graphite is used for packing of Female Threaded Gate Valve. PTFE or combined packing material can be also used if being requested by the customer. The internal surface of the stuffing box, of which area is contacted with the packing, is of excellent finish (Ra 3.2μm). The stem surface, contacting with the packing, should be rolled and pressed after being precisely machined, so as to reach to the high finish and compactness (Ra 0.8μm) and ensure the reliable tightness of the stem area.

The DIN Cast Steel Gate Valves are widely used in oil and steam pipelines, such as chemical industry, fire power plant, power plant, etc., for opening or closing the medium in the pipeline., including DIN F5、DIN F7、DIN F4 Rising Stem Gate Valve, DIN F15 Non-Rising Stem Gate Valve, DIN F1、DIN F2 Globe Valve, DIN F32 Angle Globe Valve, DIN F1、DIN F6 Swing Check Valve, DIN F1 Lift Check Valve, DIN Cast Iron Valve etc, Our products are utilized widely in oil, gas, hydraulic, refining chemicals, petrochemicals, pharmaceuticals, food industries, fire-safe systems, marine systems and power stations, etc.

The Cast Steel Slab gate valves is a sliding valve with closing parts as parallel gates. The shutter can be single gate or double gate with extension mechanism. The pressing force of the gate to the valve seat is controlled by the medium pressure of the floating gate or floating seat. If it is a double gate flat gate valve, the expansion mechanism between the two gates can supplement this compaction force.The flat gate valves can be divided into manual flat gate valves, pneumatic flat gate valves and electric flat gate valves according to the driving mode. It can be divided into flat gate valve with diversion hole, flat gate valve without diversion hole, flat gate valve of oil field, flat gate valve of pipeline and gas plate valve.

Forged steel gate valve refers to the closing piece (gate) along the path of the central line of the vertical movement of the valve. The forged steel gate valve is mainly cut off in the pipeline. Forged steel gate valve is a widely used valve, and its general caliber DN or less 50 cutting device selects it. Forging steel gate valves are more common.
