Plug Valve

The sealing property of the soft seal sleeve plug valve is realized through the sealing surface around the card sleeve. The unique 360 degree metal lip protection fixed card, the valve has no cavity to accumulate the medium, the metal lip in the rotary plug provides self cleaning effect, suitable for sticky and easy to scale the working conditions, two-way flow, the use of more convenient installation. The soft sealing cock valve is suitable for the nominal pressure CLASS150 to CLASS900, and the working temperature is -29 C ~ 180 Degree C, oil, chemical, pharmaceutical, chemical fertilizer, electric power industry and so on.

The GAIRUI Jacket Plug Valves of the American standard heat preservation card is suitable for cutting or connecting pipeline medium on the pipelines of various working conditions, such as oil, chemical, pharmaceutical, chemical fertilizer, electric power industry and so on, which are nominal pressure CLASS150-900LBS and working temperature of -29-180 Degree C. The product is reasonable in structure, reliable in sealing, excellent in performance and beautiful in appearance. Its sealing performance is achieved through the sealing surface around the card sleeve. The unique 360 degree metal lip protection fixed card.

The GAIRUI PTFE Sleeve Plug valves (full lining type) and bushing stopcock (semi lining type). Plug valves are mostly used for cutting off medium flow, and also for medium distribution (three way stopcock). The fluorine lining valve is suitable for various concentrations of water, sulfuric acid, hydrochloric acid, hydrofluoric acid and various organic acids, strong acids and strong oxidizing agents at -29~150 Degree C. FEP is also suitable for the use of various strong alkaline organic solvents and other corrosive gas and liquid medium.

The GAIRUI Teflon Lined Plug Valves (full lining type) and bushing stopcock (semi lining type). Plug valves are mostly used for cutting off medium flow, and also for medium distribution (three way stopcock). The fluorine lining valve is suitable for various concentrations of water, sulfuric acid, hydrochloric acid, hydrofluoric acid and various organic acids, strong acids and strong oxidizing agents at -29~150 Degree C. FEP is also suitable for the use of various strong alkaline organic solvents and other corrosive gas and liquid medium.

A pressure balance type oil sealed plug valve, the plug is adjusted by the bolt in the lid of the valve, and the sealant inject the valve from the end of the stem; in order to prevent pressure from pushing the plug into the valve body, the end of the plug has a balance hole, and the balance hole in the small end of the valve has no medium only to the end of the small head. When entering the cavity at the two ends of the valve plug, the sealing of the valve is sealed by the sealant between the valve plug and the valve body.

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 GAIRUI Lubricated Inverted Pressure Balance 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 Orbit Plug Valves, also known as the bevel gear drive, applies the warlords to the pipelines of aviation kerosene, crude oil, light oil, natural gas, liquefied gas, pipeline gas and chemical medium, as an ideal device for truncating medium. The key to the operation of the pun double break and discharge valve is the action of two pieces of sealing sliding vane installed on the cock. The shape of the track plug valve is close to the gate, and the way of flange connection is adopted. The design principle is reasonable, simple and beautiful, so as to meet the market demand.

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.

The unique eccentric sealing design of the eccentric plug valve greatly reduces the operating torque, reduces the wear of the sealing surface and prolongs the service life of the valve compared with the traditional plug valve. Rectangular straight channel, small head loss and good flow regulation linearity. The plug valve is suitable for working environments such as urban sewage, industrial sewage, mud and clean water. It is used as a closure or regulating device.

The GAIRUI Multi Port Plug Valves is widely used in oil field mining, transportation and scouring equipment. It is also widely used in petrochemical, chemical, gas, natural gas, liquefied petroleum gas, HVAC and general industry. The cock valve is often used in caustic environment, such as corrosive, toxic and high harm medium, strictly prohibit the leakage, and the situation that the valve material will not pollute the medium. The valve body can choose carbon steel, alloy steel and stainless steel material according to the working medium.
