PTFE butterfly valve is to adapt to some corrosive environment with strong acid, strong alkali, petroleum, chemical, food and other special areas of need, the use of PTFE made of the valve body, has a strong anti-corrosion effect. It can replace the stainless steel body under conventional conditions, with higher cost performance. The butterfly plate of the butterfly valve is installed in the diameter direction of the pipe. In the cylindrical channel of the butterfly valve body, the disc shaped butterfly plate rotates around the axis, the rotation Angle is 0°~90°, rotate to 90°, the valve brand is fully open. Below photos are PTFE Lined Butterfly Valve of Tianjin Tanghai Valve, more information please click here: PTFE butterfly Valve. PTFE (Teflon) butterfly valve can be equipped with AKR electric, BY pneumatic actuator, input control signal (4~20mADC or 1~5VDC) and single-phase power supply can control the operation, can realize intelligent type (regulating type) and switching type. With strong function, small size, light and pleasant, reliable performance, simple supporting, large circulation capacity, especially suitable for the medium is sticky, containing particles, fiber properties of the occasion. At present, the PTFE butterfly valve, as a component used to realize the on-off and flow control of the pipeline system, has been widely used in petroleum, chemical industry, metallurgy, hydropower and many other fields. In the known butterfly valve technology, its sealing form is mostly sealed structure, sealing materials for rubber, PTFE, etc. Due to the limitation of structural characteristics, it is not suitable for high temperature resistance, high pressure resistance, corrosion resistance, wear resistance and other industries.

A gate valve is a gate plate of an opening and closing part. The movement direction of the gate plate is perpendicular to the direction of the fluid. The gate valve can only be fully opened and fully closed, and cannot be adjusted or throttled. The gate valve is sealed by the contact of the valve seat and the gate plate. Usually, the sealing surface will be welded with metal materials to increase wear resistance, such as 1Cr13, STL6, stainless steel, etc. The gate has a rigid gate and an elastic gate. According to the different gate plates, the gate valve is divided into a rigid gate valve and an elastic gate valve.

Less effort when opening and closing. Large height and long opening and closing time. Water hammer phenomenon is not easy to produce. The reason is the long shutdown time. The medium can flow in any direction on both sides, easy to install. The structure length is small. The shape is simple, the structure length is short, the manufacturing process is good, and the application range is wide. The structure is compact, the valve has good rigidity, the channel is smooth, the flow resistance is small, the sealing surface is made of stainless steel and hard alloy, and the service life is long. The use of PTFE packing is reliable and easy to operate. Disadvantages The overall dimensions and opening height are large. The space required for installation is large. During the opening and closing process, there is relative friction between the sealing surfaces, which can easily cause scratches. Gate valves generally have two sealing surfaces, adding some difficulties to processing, grinding and maintenance. Related types of valves: We can also produce check valve, globe valve, knife gate valve and ball valve with API, JIS, DIN standard, used in Oil, Gas, Marine industry, Water supply and drainage, fire fighting, shipbuilding, water treatment and other systems, with Nominal Diameter of DN50 to DN1200, NBR/EPDM/VITON, Certificates & Approvals: DNV-GL, Lloyds, DNV, BV, API, ABS, CCS.
