ball valve series-九游官网下载

product description

pneumatic three-way flanged ball valve is a three-channel rotary ball valve, which is used for media splitting, confluence and flow direction switching. any pipe can be used as an inlet or an outlet. there are two types of pneumatic three-way l-type ball valve and pneumatic three-way t-type ball valve, which can meet different business process requirements. the pneumatic three-way l-type ball valve cuts off two of the three pipelines, and the pneumatic three-way t-type ball valve realizes the confluence and shunting of the three connected pipelines. pneumatic three-way flanged ball valve is matched with electric valve positioner. input 4~20madc signal and 0.4~0.7mpa air source to control operation, and realize the adjustment of pressure, flow, temperature, liquid level and other parameters. it is also equipped with travel limit switch, solenoid valve, pressure reducing valve and 0.4-0.7mpa air source to realize switch operation, and send two pairs of passive contact signals to indicate the switch of the valve. widely used in chemical, petroleum, textile, electric power, food and pharmaceutical, refrigeration, aviation, aerospace, papermaking and other industrial fields.

product features

1. the fluid resistance is small, and its resistance coefficient is equal to the pipe section of the same length.

2. simple structure, small size and light weight.

3. tight and reliable. at present, the sealing surface material of the ball valve is widely used in plastic, which has good sealing performance, and has also been widely used in vacuum systems.

4. easy to operate, open and close quickly, just rotate 90° from fully open to fully closed, which is convenient for long-distance control.

5. it is easy to maintain, the structure of the ball valve is simple, the sealing ring is generally movable, and it is more convenient to disassemble and replace.

6. when fully open or fully closed, the sealing surface of the ball and the valve seat is isolated from the medium, and the sealing surface of the pneumatic three-way ball valve will not be eroded when the medium passes through.

7. wide range of applications, diameters ranging from small to several millimeters, large to several meters, and can be applied from high vacuum to high pressure.

executive standard

remarks: the structural length and connection size of the series ball valves can be designed and manufactured according to customer requirements.

the main technical parameters

material of main parts

remarks: other special sealing materials or special temperatures can also be designed and manufactured according to customer requirements.

main external connection dimensions-pn16（16bar）

main external connection dimensions-pn25（25bar）

remarks: according to different valve torque, different air source pressure and different actual working conditions, the relevant external dimensions of the matching actuator will also change accordingly.
