Teflon Lined Plug Valve

A pressure balance type flip plug valve, consisting of a valve body, a cock, a stem and a filler, the cock is a conical valve plug over the upper end of the upper end, the cock is located in the inner cavity of the valve body, the stem driving cock rotates, the sealing surface of the cock is a cone, the stem and the cock are connected through the cross connector, and a cylinder between the stem and the cock is equipped with a cylinder. Spring or butterfly spring, the lower end of the valve body is fixed with a valve cover, the valve cover has a adjusting shaft, the lower end of the adjusting shaft is worn out of the valve cover and the top top cock, the lower end of the cock has a first check valve, the seal face of the cock is equipped with a seal oil tank, the valve body has a tank, the oil tank of the valve body is connected with the seal oil tank of the cock. The valve body is provided with an oil injection valve that is connected with the oil storage tank. The pressure balance type flip plug valve can be used under high temperature, high pressure and harsh conditions. It has the advantages of reliable sealing, small operating torque and long service life.

The KOSEN Pressure Balance Type Double Plug Valves is a valve that opens and closes the closing part (the stopper) rotating around the center line of the valve body. Plug valves are mainly used for cutting, distributing and changing the direction of media flow in pipelines. Plug valves are the earliest valves used in history. Because of its simple structure, fast opening and closing (the 1/4 circles of the plug can complete the opening and closing action), the operation is convenient, and the fluid resistance is small, so far it is widely used. At present, it is mainly used for low pressure, small caliber and medium temperature. The stopper and plug body of the stopcock is a good conical body.

The KOSEN High Pressure Plug Valves is a fast switch direct through valve. Because the motion of the cover is wiping, it can completely prevent contact with the flow medium in full opening, so it can usually be used in medium with suspended particles. Another important feature of it is that it is easy to adapt to multi-channel structure, so that a valve can get two, three or even four different channels. This can simplify the design of pipeline system, reduce the amount of valve and some connection accessories needed in the equipment.

The metal hard seal lifting plug valve uses the first lifting and closing valve operation mode, which greatly reduces the opening and closing torque of the cock valve, and is different from the traditional cock valve using the rectangular diameter channel. The valve usually uses a circular channel to reduce the fluid resistance of the cock valve greatly, and the metal hard sealing lift type cock valve is also used. The ball valve and the gate valve are a little bit, can be used in high temperature and high pressure conditions, and greatly expand the use scope of the stopcock.
