Sudhanafluid pneumatic valve series: butterfly valve 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 with a rotation angle of 0 �°~90 �°. When the rotation angle reaches 90 �°, the valve is fully open. The butterfly valve is simple in structure, small in volume and light in weight, and only consists of a few parts. Moreover, the valve can be quickly opened and closed only by rotating 90 �°, which is simple to operate. 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 resistance when the medium flows through the valve body, so the pressure drop generated by the valve is very small, so it has good flow control characteristics. The butterfly valve has two sealing types: elastic seal and metal seal. For elastic sealing valves, the sealing ring can be embedded on the valve body or attached to the periphery of the butterfly plate. The valve with metal seal is generally longer than the valve with elastic seal, but it is difficult to achieve complete sealing. The metal seal can adapt to higher working temperature, while the elastic seal has the defect of being limited by temperature. If the butterfly valve is required to be used for flow control, the main thing is to correctly select the size and type of the valve. The structure principle of butterfly valve is especially suitable for making large diameter valves. Butterfly valves are not only widely used in petroleum, gas, chemical industry, water treatment and other general industries, but also used in the cooling water system of thermal power plants. There are two kinds of butterfly valves commonly used: wafer type butterfly valve and flange type butterfly valve. Wafer type butterfly valve uses stud bolts to connect the valve between two pipe flanges. Flange type butterfly valve has flanges on the valve, and bolts are used to connect the flanges on both ends of the valve to the pipe flanges.
A Complete Guide To Gate Valve The gate valve is the most common shut-off valve. Unlike ball valves, they are not quarter-turn devices; instead, they close and open through revolutions of the hand wheel. Used in wastewater plants, power plants and process systems, the threaded system of the gate valves give them an advantage over the quarter turn system of the ball and butterfly valve in large applications. Fluid through gate valves experiences only minimal pressure drop as gate valves allow total flow through its passage when fully open. This post discusses the functions, symbols, advantages and disadvantages, types, and other essential things you need to know about the gate valve. What is A Gate Valve? Gate valves can also be called sluice valves or knife valves. They are control valves that allow or restrict the flow of media completely. Gate valves use a flat gate to close off flow between pipe flanges. A gate valve, being a full port valve, has an equal diameter to the pipe through which the fluid passes. Hence, unlike butterfly valves, gate valves minimise pressure losses in the fluid when fully open. Also, because of the equal pipe and valve diameters, gate valves allow for the movement of pigs within the pipe for cleaning and inspection operations. While butterfly valves can be used in flow regulation and on-off services, gate valves should only be used in on-off services as blocking valves and also to allow fluid flow. They should not be used in throttling. Because of their uncomplicated construction and capability to be used in different low-pressure applications, gate valves are one of the most common valves in the industry. Gate Valve Symbol The gate valve symbol is composed of two triangles meeting at a point. A vertical line is inserted between the triangles, and solid horizontal lines extend from the opposite sides of the triangle. The vertical line indicates the blocking operation of the gate valve, and the horizontal lines show that the valve has a two-way function in on-off applications. The gate valve symbol used in piping and instrumentation diagrams (P&ID) is a modification of the valve symbol, which is the gate valve symbol without the vertical line between the triangles. The three isometric symbols in the diagram indicate symbols for butt-welding end connections, flanged ends, and socket ends connections.
Product Description It is a kind of tankless, lager-caliber tube and low-pressure solar water heater system with the following features: Capacity: The system contains 4-8 pieces of vacuum tubes as one unit, with each tube capacity of 16 liters of water. this one is 4 pieces of vacuum tubes as one unit. Tankless: Inside each tube, there is a high-temperature-resistant and corrosion-resistant stainless-steel cylinder made of food-grade 304/316 material, so the solar heater does not require a water tank like other products in the market, thus saving space. Pressurized mode: the heater is pressurized. It is connected to the tap-water supply system and on the other side it is connected to the shower head in the bathroom, so the pipeline is relatively simple, and the installation and maintenance are also simple and convenient. Flexible installation position Because this water heater is connected to tap-water supply system(pressurized), it can be installed anywhere for buildings, such as on the ground, the roof, the balcony, the terrace etc., whether high-rise building, multi-story building, bungalow or villa. Installation method: vertical, horizontal, inclined etc. installation Limescale prevention: Pre-filter as a standard feature gives an effective limescale prevention solution to avoid any potential worry. Excellent insulation: Each tube is equivalent to a thermos bottle, which has good insulation performance, and there is air between the steel cylinder and the glass tubes, which also provides the added thermal insulation. and the tube openings are also insulated by good materials, ensuring optimal heat retention. Based on our experiments conducted on the rooftop of an eight-story building, with daytime temperatures reaching 7C and nighttime temperatures dropping to -3C or -5C, it is observed that when 15C water was injected at 9 AM, the water temperature ranged from 51C to 64C at 17:00 PM. The following morning at 8 AM, the water temperature ranged from 42C to 47C, and by 17:00 PM, the temperature of the hot water reached 85C. The highest energy efficiency: due to its large area of absorption of sunlight, it is with good energy efficient whose hot water outlet is the highest. Automatic anti-freeze function: when the temperature falls below 5 C, the system will automatically activate the anti-freeze electric heating feature. optional devices: electric auxiliary heating pump station, gas water heater, electric water heater can be added to our heater system as auxiliary components to be used if weak or lack of sunlight. Customers can choose one out of above-mentioned three.

Pneumatic valve is a valve driven by compressed air. When purchasing pneumatic valves, only the specification, type and working pressure are specified to meet the purchase requirements, which can be used to control the flow of air, water, steam, various corrosive media, mud, oil, liquid metal, radioactive media and other types of fluids.
