Q641F-16P AT Pneumatic Stainless Steel Flange Ball Valve

Pneumatic stainless steel flange ball valve

[ Q641F-16P pneumatic stainless steel flange ball valve ] is mainly used to cut off or connect the medium in the pipeline, it can also be used for the adjustment and control of fluids, and the plug valve is a valve of the same type, only its closing part is a sphere The ball rotates around the centerline of the valve body to open and close a valve. The ball valve is mainly used in the pipeline to cut off, distribute and change the flow direction of the medium. [ 641F-16P Pneumatic Stainless Steel Flange Ball Valve ] is a new type of valve that has been widely used in recent years. In all kinds of valves, the ball valve has low flow resistance. When the full-path ball valve is opened, the ball passage, valve body passage, and connecting pipe diameter are equal and become a diameter, the medium can flow through without any loss, and the ball valve can be rotated by 90°. Close full, open and close quickly. Compared with the same specifications of the gate valve, globe valve, ball valve, small size, light weight, easy to install the pipeline.

Pneumatic stainless steel flange ball valve product uses and features:

[Q641F-16P pneumatic stainless steel ball valve] pneumatic ball valve is widely used in natural gas, oil products, chemical, metallurgy, paper and electricity office, mining, printing and dyeing, bio-pharmaceutical, daily-use chemical, food and beverage, water treatment and air treatment industries such as fluid automatic Control or regulation control, reliable sealing, simple structure, easy maintenance, sealing surface and spherical surface are often in the closed state, not easy to be eroded by media, and widely used in various industries. [Q641F-16P Pneumatic Stainless Steel Ball Valve] Only need to rotate with 90 degrees of operation and a small torque can close the tight. The completely equal valve body cavity provides a small, straight flow path for the medium. Ball valves are generally considered to be suitable for direct opening and closing use, but recent developments have designed the ball valve to be used for throttling and controlling flow. [Q641F-16P Pneumatic Stainless Steel Ball Valve] Its main feature is its compact structure, easy operation and maintenance, applicable to water, steam, oil, liquefied gas, natural gas, gas, nitric acid, acetic acid, oxidizing medium, urea, etc. Medium.

1. The fluid resistance is small, and the resistance coefficient is equal to that of the same length.

2. Anti-static function: Set a spring between the ball, valve stem and valve body to export the static electricity generated during the switching process.
3, the valve seat sealing performance is good, using PTFE and other elastic materials made of seals, the structure is easy to seal, and the ball valve sealing ability increases with the increase of medium pressure.
4, easy to operate, open and close quickly, from full open to full off as long as the rotation 90 °, easy to control the distance.

5, easy maintenance, ball valve structure is simple, the seal ring is generally active, removal and replacement are more convenient.

6. When fully open or fully closed, the sealing surfaces of the ball body and the valve seat are isolated from the medium. When the medium passes through, the sealing surface of the valve will not be eroded.

7, a wide range of applications, from a small diameter to a few millimeters, up to a few meters, from high vacuum to high pressure can be applied.

Double acting pneumatic flange ball valve working principle:

Pneumatic ball valve opens: 2 inlets, 4 outlets, push the two pistons to move to both sides, the output shaft rotates counterclockwise

Pneumatic ball valve closed: 4 intakes, 2 exhausts, push the two pistons to the center and the output shaft rotates clockwise

Single-acting pneumatic stainless steel flange ball valve Working principle: 2-hole intake valve opens, valve closes after the air is closed

Pneumatic flange ball valve cylinder and its accessories:

Pneumatic flange ball valve composition and the role of accessories

Pneumatic flange ball valves consist of pneumatic actuators and flange ball valves. Flange ball valves are equipped with different pneumatic actuators and pneumatic accessories for different control functions.

Equipped with double-acting pneumatic actuators: A port intake, ball valve open, port A gas, ball valve remains open, B port intake, ball valve closed, B port gas, ball valve closed.

Equipped with single-acting pneumatic actuators: Air intake at port A, ball valve open, air at port A closed, ball valve closed.

Equipped with solenoid valve: Two-position three-way solenoid valve used in single-acting pneumatic actuator, two-position three-way solenoid valve is generally a single electric control, power, the valve opens, power off, the valve closes; two five-way solenoid valve used in Double-acting pneumatic actuator, two-position five-way solenoid valve is generally double electric control, with memory function, coil A is energized, PA is ventilated, valve is opened, coil A is de-energized, PA remains vented, valve remains open, coil B is energized, PB is vented, the valve is closed, coil B is de-energized, PB is deactivated, and the valve remains closed. Two-position five-way solenoid valve also has a single electronic control, two five-way single electronically controlled solenoid valve, 2-position 5-pass, P is the air inlet, air source. A, B is the air outlet, where it is used. R, S is the exhaust port, connected to the muffler, A is a constant opening, that is, a breath from the A outlet. Power or manual control is B outlet. (Solenoid valve can provide explosion-proof type)

Equipped with pneumatic two-piece: including air pressure reducing valve filter, oil mister, lubricating the air source stable, clean and moving parts.

Equipped with a limit switch: also known as reverberator, echo receiver, long-distance transmission valve opening and closing position signal (can provide explosion-proof type).

Equipped with hand wheel mechanism: automatic control can manually open and close the valve under abnormal conditions.

Electric positioner: According to the size of the current signal (4-20mA), the media flow control of the valve is controlled (explosion proof type available).
Pneumatic positioner: According to the pressure signal (standard 0.02-0.1MPa) size of the valve media flow regulation control.
Electrical converters: Convert current signals to pneumatic signals for use with pneumatic positioners (explosion-proof versions are available).
