Pneumatic Hastelloy Ball Valve

Product Overview

Pneumatic Hastelloy Ball ValveIt is a pneumatic switch valve, in which the opening and closing member (ball) is driven by the valve stem and rotates around the axis of the ball valve,It is mainly used for cutting, distributing, and changing the flow direction of media. It only requires a 90 degree rotation and a small rotational torque to close tightly.

Pneumatic Hastelloy ball valves are widely used in industries such as petroleum refining, long-distance pipelines, chemical, papermaking, pharmaceuticals, water conservancy, power, municipal, and steel

Product Features

1. Low flow resistance

2. Simple structure

3. Small size and light weight

4. The sealing surface material of the ball valve is made of plastic, which has good sealing performance

5. Easy to operate, quick opening and closing, convenient for remote control

6. Easy to maintain, the sealing ring is generally movable, and easy to disassemble and replace

7. When fully open or fully closed, the sealing surfaces of the ball and valve seat are isolated from the medium, and the passage of the medium will not cause erosion of the valve sealing surface

Installation Introduction

1) Remove the protective covers on both sides of the flange end and rinse and clean with the valve * open.

2) Before installation, the entire machine should be tested according to the specified signal (electric or gas) to prevent vibration from affecting performance during transportation. Only after passing the test can it be installed online (wiring should follow the electric actuator circuit diagram).

3) Before connecting to the pipeline, it is necessary to flush and remove any remaining impurities in the pipeline (which may damage the valve seat and ball).

4) During installation, please do not use the actuator part of the valve as a lifting point to avoid damaging the actuator and accessories.

5) This type of valve should be installed in the horizontal or vertical direction of the pipeline.

6) The pipeline near the installation point should not have any low hanging or external force bearing phenomenon. Pipe supports or supports can be used to eliminate the deviation of the pipeline.

7) After connecting to the pipeline, please cross tighten the flange connection bolts with the specified torque.
