Our sell signal butterfly handle groove

Handle trench signal butterfly was my company to introduce the United States and Germany, the same advanced technology products, the use of advanced technology and designed a series of new connector valve manufacture. In addition to the traditional signal performance butterfly valve installed outside it has a fast, simple, safe, reliable, and free from the installation site restrictions, piping and valves for easy maintenance with soundproof isolation within a certain range of angles and pipe connections have to overcome different axes produce poor imitation solve the resulting temperature difference between expansion and contraction, etc.. The sealing butterfly handle trench signal mode and connection shaft and disc are granted utility model patents. Widely used in transmission fluid to drinking water pipes, heating pipes, drainage, fire, air, gas, petroleum, chemical, water treatment, municipal, shipbuilding and other pipeline projects as a control fluid action. Handle trench signal butterfly valve worm, the worm gear, along with the cam rotates at a predetermined position on the signal device contacts depressed or released, the corresponding output "on" "off" signals, displays the status of the butterfly valve opening and closing. The trench signal butterfly handle small, lightweight, easy installation and maintenance, and can be installed anywhere. Handle trench signal butterfly Advantages: 1. Using patented technology, the valve seal is more reliable, but also has a two-way sealing function. 2 disc streamlined, hydraulic grinding resistance is small. 3 easy to install, can be any angle with the other grooved fittings or valves for fast connections. 4 body ductile iron manufacturing, small size, light weight. 5 hoist lightweight low torque operation, opening and closing the valve body lightweight unbreakable 6, ductile iron and outside epoxy powder coating, effectively prevent various corrosive acid medium insurable durable. 7 Communications reliable micro switch mounted on the worm cabinets, improve fire, moisture, moisture capacity, improve the life and reliability of communications devices.
