Clamp butterfly valve Features 1, efficient groove clamp contact and take the appropriate placement of pipe fittings, do not want to start the welding, unnecessary secondary zinc, secondary placement. Increase the placement rate. 2, light weight portable clamp contact, less the number of bolts, easy placement, unnecessary extra skills. 3, reliable scientific and rational planning the organ, unique C-type rubber seals to achieve triple seal, guarantee the bond seal reliability. 4, safe contact with the trench and the corresponding clamp tube placement start Shanghai Guanlong valve Machinery Co., just mechanical assembly, no welding, no fire, so Guangzhou Kaiheng Valve Co., no turbidity pipe welding slag, ensure site safety, fire ban to commence under the conditions of the case, it is particularly appropriate. Why the double flapper valve small opening in the work easy oscillation? For single-core, when the medium is the flow of open type valve stability; when the medium is the flow of closed type, the stability of the valve difference. There are two spool valve seat under the spool in the flow closed, the valve is open flow, so that when the small opening, the flow of closed type valve spool is easy to cause vibration, which is double flap valves The reason can not be used where the small opening.
