A floating valve is mainly used to keep the liquid in a tank at a specific level. The main specifications include the intended application, gate connections, valve size, float size and materials that make up the valve body, sealing and floating. Floating valves are used in bath toilets to replenish the water level after washing and in many tank level control systems. Balance valves are used to control the flow of liquid by evenly dividing the flow into multiple flow branches. The main specifications are the number of ports, gate connections, valve size and building materials. Balance valves are mainly used in HVAC applications and fluid feeding systems.

The main advantage of a balloon valve is that it does not leak as much as other valves. A full-caliber API 6D ball valve generally has a smaller hole diameter than the tube. As an example, API ball valves with a full diameter of 22Cr class 150 in 22Cr duplex material can have a diameter up to 10-12 mm smaller than the tube. The 22Cr duplex tube has no corrosion margin and less thickness, giving it a larger hole compared to the valve and also compared to carbon steel pipe. The minimum hole diameter is 90% of the inner diameter of the valve end according to ASME B16.34, which is the standard for valve design.

The stumped chair is designed to power the chair by upstream pressure and is forced to seal the ball. Because the ball remains firmly in place, except for the 90 ° rotation, the extraordinary fluid and compressive force does not block the ball in the seat. Instead, the force only works in a small area on the circumference of the floating seat.

And depending on the operating pressure, ball valves are classified as low-pressure ball valves and high-pressure ball valves. In most industries, ball valves with working pressures above 3000 psi are considered high pressure ball valves. The working pressure for high-pressure ball valves is 7500 psi and depends on the structure, dimensions and sealing materials, the maximum. High pressure ball valves are mainly used in high pressure applications, such as hydraulic systems, which is why they are also known as hydraulic ball valves. Three-piece ball valves are used for applications that are highly dependent on valves, which often have to be performed.

The main specifications include valve type, gate connections, valve size and building materials. Rooster valves are used in various product applications, including radiators, stoves, tanks, boilers, laboratory glassware, air systems, tanks, vessels, etc. The throttle is possible in ball valves, but should be maintained for a long time. When the ball valve is in an acceleration position, the seats are exposed to a high speed and increased compression force, causing erosion. Segmented ball valves can be used in applications with limited acceleration. Advanced ball valves with modified designs or seats made from designed materials suitable for acceleration applications are commercially available.

They are also more prone to leakage than ball valves and are subject to more head loss. Flow control valves are necessary components in a wide range of industries. As for tube valves, many can be considered suitable for blocking or strangling. A ball valve is more suitable for on and off applications than for controlling the flow. Balloon and butterfly valves are preferred options for flow control, with balloon valves that are particularly common.

Compared to other valves with similar classifications, ball valves are relatively small and light. If you’re wondering if a wedge-shaped gate valve can be selected alternately, the answer is no. A 2 ″ class 1500 wedge lift valve cannot provide a full hole according to the API 602 standard covering the ports, balloon and check valves for size 4 ″ and smaller in the oil and natural ecozen gas industry. The minimum hole of a sliding valve in the above size and pressure class is 38 mm, which is smaller than the hole of the ball valve according to API 6D Manually operated ball valves can be closed quickly and therefore there is a danger of a water hammer. Some ball valves are equipped with a drive that can work pneumatically, hydraulically or with an engine.

System administrators can use a flow control valve to quickly make a handy hose pressureless and quickly replace accessories. They are also used in many consumer applications, such as showers, taps and lawn irrigation systems, to easily reduce the amount of water consumed without affecting overall system performance. Flow control valves are also known for their reliability and generally have a long life because they are not susceptible to blockage due to their design. Except for the example of the ball valve near the above flow element, pipe valves must have a special hole equal to or close to the inner diameter of the pipe, by the operation of the PIG. Although the pipe valves are designed based on 6D API, the diameters with a minimum diameter in 6D API are not necessarily piggable. The hole in a valve is usually less than the thickness of the tube, especially when the tube is made of 22Cr duplex material.
