fire fighting gate valve,
fire check valve
This butterfly valve is suitable to temperature<80℃, is used on pe-troleum, chemical industry foodstuff medicine gently the spinning and papermarking, power, plumbing and gas pipe route, and does the effect adjusted the volume of flow and dams a river the medium. Possess the bloated cold function that contracts of compensation pipeline heat.
This butterfly vavle is suitable on system such as petroleum, chemical industry, foodstuff, medicine, papemaking, water and electricity, shipping, plumbing, the smelting and sources of energy etc the pipe route. Can regard on gas, liquid, semifluid as well as solid powder pipes and power lines and the container of many kinds of corrosiveness and non-corrosiveness adjusts and dams a river the equipment use. Especially extensively being in high layer of building fire protection system reaches other to show in the pipes and power lines system of valve of vavle switch state.
The disc of the wafer type butterfly valve is installed in the diameter direction of the pipe. In the cylindrical passage of the butterfly valve body, the disc-shaped disc rotates around the axis, and the rotation angle is between 0°-90°, which can play the role of flow regulation. When the disc rotates to 90°, the valve reaches the maximum. Opening degree.
The clip-on butterfly valve is simple in structure, small in size and light in weight, and consists of only a few parts. Moreover, it can be quickly opened and closed by only rotating 90°, and the operation is simple, and the valve has good fluid control characteristics.

Note: there are two data in the table, respectively, PNI.OMPa and PN0.6MPa, respectively, the size of two different pressure levels.
1. The design is new and original and reasonable and the structure is unique and is light in weight and operates makes things convenient and it is rapid case to close.
2. This strech butterfly vavle can act to adjust the volume of flow with damming a river the effect, to compensate that the pipeline difference in temperature is given rise to again hot expands to cool contracts the function, and but also being easy to at the same time install and dismanteles, uses the product for one vavle more.
3. Simple and compact structure, light weight, 90 degrees rotation, quick and flexible opening and closing.
4. Ecentric structure allows reduce friction with seal ring andextended service life.
5. Sound sealdesign gives a full sealing without any leakage, thus ensuring a reliable application in adverse working condition.
6. By changing disc seal ring, o-ring, disc, shaft and the like, the product can be used in many different media and temperature conditiions.
7. The vavle body is provided with foundation support, so it can be installed either vertically or horizontally.
8. Easy to mount and dismantle thus convenient for servicing.
