Investment Casting Screwed Gate Valve
The opening and closing part of the thread gate valve is a plug valve, the sealing surface is flat or conical, and the valve flap moves straight along the centerline of the fluid. The motion form of the stem has the lifting rod type (the stem lift, the handwheel not lifting), also the lifting and rotating rod type (the handwheel and the stem rotates with the lift, the nut is located on the body).

Bellow Sealed Gate Valve
The valve stem of the bellows valve adopts double sealing structure of bellows and packing to ensure the leakage and seal at the stem, especially for flammable, explosive, toxic and valuable medium. Bellows are made of stainless steel or Inconel material. The bellows seal structure is reasonable, fatigue resistant and long service life.

Extended Body Gate 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.

Cast Bronze Gate Valve
KOSEN Cast Bronze Gate Valves are designed and manufactured to ensuru leakage of less tjan 100 ppm(parts per million) of volatile organic compounds. Extensive base line laboratory testing (static and cycle testing) has been performed establishing critical design parameters necessary to achieve low emission sealing in the KOSEN stem packing seal area and in the bonnet gasket sealing area, in-house testing procedure has been developed and is periodically performed to ensure that standard product design and manufacting criteria consistently result in the KOSEN Cast Bronze Gate Valve meeting a maximum of 100ppm Voc leakage prior to shipment.

Flanged End Pressure Seal 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.
