Product Overview
The fire signal Butterfly valve and normal signal butterfly valve we developed, has successfully past the examination of public security inspection center. The product has high performance, reliability, and long service life, special for high rise construction fire control system. Has widely used in the field of petrochemical, medical, food, water supply, metallurgy, energy and Other system which needed display of switching situation and output signal. adapted for various of mediums conclude gas, liquid, powder, to adjust or stop the flow.
Products features
1. The fire signal butterfly valve conform to GB5135.6-2003, the inspection of seal, strength, performance is far above test for normal valve, to guarantee the reliability of product.
2. Adopting no-pin connection technology, reliable and long service life, keep long term zero leakage; coaxial type structure, eliminate the impaction of cumulative error, accurately reflect the on/off state of valve, the product can output two geometric position signal.
3. Use several of materials like nylon, PTFE, corrosion resistant alloy, can satisfy different of requirements of mediums.
4. Use proxy resin coatings, good appearance, and high corrosion resistance. Electrical switch box is whole sealing structure, all connecting areas set seal washer, therefore, totally suitable for indoor/outdoor.
5. Valve and signal device are qualified before delivery, customer could use it directly after installation according to circuit diagram.
Operating principle
Rotate hand wheel drive worm gear and stem, to switch and adjust the disc.
Transmission device set two jogging switch, take motions at the fully opening or closing state, the signal device will connect the local and remote control room automatically.

Matters need attention for installation
1. Pipeline wafer type flange standard should be in accordance with the standard of butterfly valve, dedicated flange of butterfly valve is recommended for wafer type connection flange.
2. Users should check the working conditions if it is accordance with the butterfly valve.
3. Lumen and sealing surface should be cleared up before installation, no waste adhering.
4. Both side of valve seat extruded as seal washer of flange, no need to use seal washer for butterfly valve
5. The butterfly valve could be installed at horizontal, vertical and any other angles of pipelines, and could be used in two-way.
6. The butterfly valve can not be installed at the corners of pipeline, no handstand installation allowed.
7. The butterfly valve must be closed when installing, to assure valve plate not to impact with the pipeline flange.
8. Verify flange welded without defects. Can not weld after installation to avoid to scald rubber articles and antiseptic coatings.
9. For abnormal situations on switching, should check it out, remove faults, do not open or close the valve with external force.
