Valves

Description DCL series high vacuum ball valves are widely used for silicon panel production equipments in Solar energy industry and semiconductor industry. Valves can be used for pipe pressure from 105Pa to 1.3*10-4Pa with zero leakage. Electric actuator can be modulated with positioning error＜1%, by kinds of input signals, such as 4-20mA, 1-5V, 2-10V, and can be chosen and calibrated by customer.

The bottom of the soft seal gate valve adopts the same flat bottom design as the water pipe, which is not easy to cause debris silting and make the fluid unobstructed. 2 Whole package The valve uses high-quality rubber for the whole inside, outsourcing glue, domestic first-class rubber vulcanization technology makes vulcanized valve can ensure accurate geometry, and rubber and ductile iron valve then firm, not easy to fall off and elastic memory is good. 3 corrosion The valve body is coated with powder epoxy resin to prevent corrosion and rust. And can be used in sewage systems. In the past, the traditional cast iron gate valves were often broken due to the impact, collision or overlap of external objects. Due to the use of nodular cast iron, this situation has been greatly reduced. 4 three "O" type Because the valve stem uses three "O" type ring seal ring design. Can reduce the friction resistance when the switch, greatly reduce the phenomenon of water leakage and can not stop the construction of replacement seal ring. 5 helps to drink raw As the valve body is coated with non-toxic epoxy resin, the internal and external surfaces of the gate valve are completely covered with rubber to prevent rust or corrosion. 6 Cast valve body The valve body is precision cast and the precise geometry ensures the valve sealing without any finishing in the north of the valve body. 7 light weight The body is made of ductile casting, the weight is reduced by about 20% to 30% compared with the traditional gate valve, convenient for maintenance.

Butterfly valve is different from the ball valve, the valve flap is always present in the fluid, so regardless of the valve position, the fluid will always produce a pressure drop. What is butterfly valve used for? The butterfly control valve is mainly suitable for large diameter, large flow, thick slurry and suspended particles of fluid flow regulation. The drive form has manual, worm gear drive, electric, pneumatic, hydraulic, electro-hydraulic linkage and other ways. With simple structure, small volume, light weight, material consumption, small installation size, rapid switching, 90 ° reciprocal rotation, small driving torque, etc. Liwei is a professional manufacturer of butterfly valves, and the valves we supply comply with ISO9001 international quality system certification standards. What is the difference between check valve and butterfly valve? Butterfly valve is a manual valve, which only does the switching function. Check valve is an automatic valve, which is to prevent the backflow of the pipeline medium. If you have any problems about butterfly control valves, pls contact us on time. The driving mode of the lug type butterfly valve can be manual, worm gear, pneumatic, electric, the connection mode can be flange, butt clamp, the structure can be single eccentric, center line, double eccentric, triple eccentric,and the sealing structure can be soft seal or hard. Sealed, the pressure range is PN0.1-10Mpa, the nominal diameter is DN40～2000mm, and the material can be cast steel or stainless steel. Due to the wide range of use of valves, the same valve has different collocations in different occasions and working conditions. Advantage The wafer butterfly valve is connected between two pipe flanges with stud bolts. Its structure is simple, small in size and light in weight, and it consists of only a few parts. Moreover, it can be opened and closed quickly by rotating 90°, and the operation is simple. At the same time, the valve has good fluid control characteristics.  When the butterfly valve is in the fully open position, the thickness of the butterfly plate is the only resistance when the medium flows through the valve body, so the pressure drop generated by the valve is small, so it has better flow control characteristics. The butterfly valve has two sealing types: elastic seal and metal seal. Elastic sealing valve, the sealing ring can be inlaid on the valve body or attached to the periphery of the butterfly plate.

Double Eccentric Butterfly Valve U type butterfly valve -LWBV-6 is a normal type of butterfly valve. U-type butterfly valve is widely used in coal chemical, petrochemical, rubber, paper, pharmacy and other pipelines as media splitting, confluence or flow direction switching device. The U-shaped butterfly valve adopts a top-mounted structure, which reduces the connecting bolts of the valve body under the conditions of high pressure and large diameter, enhances the reliability of the valve and can overcome the influence of the weight of the system on the normal operation of the valve. It is very advantageous in industrial applications. U type butterfly valves are very reliable and require little maintenance.

China Manufacturer Rotary Airlock Valve For Vacuum Suction Conveying System Product Introduction The working thoery of the rotary airlock valve is to adopt the principle of rotating the impeller and adopt flange connection, which is installed at the discharge port with pressure difference to ensure that the air pressure in the conveying pipe does not leak. While feeding continuously and uniformly, the air circuit is blocked to ensure the use of system. The electric air lock valve relies on the rotating impeller to transport materials, and at the same time plays a sealing role, preventing air from sucking in the outlet during the pneumatic conveying process, and ensuring safe conveying and collecting of materials.

Introduce A Ball valve is a quarter-turn rotary motion valve that uses a ball-shaped disk to stop or start the flow. It resembles a plug valve in many ways. When a port in the ball is in line, it allows flow whereas when you rotate the valve 90 degrees, solid part of the ball stop the flow. Most ball valves are of the quick-acting type, which requires a 90° turn of the valve handle to operate the valve. But in case large size valve which required considerable force to open or close the valve, the gear-operated actuator is used. With this arrangement, a small handwheel is enough to operate a fairly large valve. In this article, I have covered following types of Ball Valves that used in piping.

It can be used in air, gaseous, and vapor services as well as hydrocarbon services. Metal seated valves can be used in high-pressure & temperature applications. it is widely used with instrument tubing to connect instruments. Advantages It is quick to open and close type that provides bubble-tight reliable sealing in high-pressure temperature applications. It is smaller and lighter than a gate valve of the same size and rating. Several designs of ball valves offer the flexibility of selection so that you can choose the valve that suits your requirements. Easy to operate and Cost-effective maintenance. Features: 1.

Time(days) 25 To be negotiated Types of Ball Valves: Although ball valves can be divided into many types based on the functionality, there major two categories are given below: Floating Ball Valve: A floating ball valve does not have any anchor for holding the ball. However, there is a stem that is attached to the ball. Due to this reason the fluid freely moves the ball downwards according to the pressure of the flow. A floating ball valve is considered a great choice for regulating the flow of the valve. Trunnion Ball Valve: Unlike the floating ball valve, trunnion ball valve comes with an anchor on both sides of the ball. This additional support provides pivot to the ball and helps contain the huge flow. Due to this reason, trunnion ball valves are very popular for the applications, which involve the flow of high-pressure valves. 4 Way Ball Valve SS316 Body / Ball / Stem PTFE seats Flange ANSI Class 150 Ball Valve 0
