GB flanged ductile iron butterfly valve D341X-16Q

D341X flange rubber butterfly valve This valve can be used for cutting media, but also for the regulation of the flow of media used. Drive device according to user requirements, respectively, can be manual, electric, pneumatic and other methods. Shanghai Hongfeng butterfly valve using different materials, parts, with different materials, seals, can be adapted to different media, working conditions, the cost and performance to achieve the best results. It is the preferred butterfly valve for pipeline selection. It is suitable for industries such as temperature ≤120 ℃ or ≤150 ℃, nominal pressure ≤1.6MPa for water supply, drainage, sewage, food, heating, gas, shipping, hydropower, metallurgy, energy system and textile. The structure is simple, the flow resistance coefficient is small, the flow characteristics tend to be straight, no debris will be retained. And light weight, easy installation, the advantages of smaller drive torque. D341X flange rubber butterfly valve works: Rotary center of the disc (ie, the center of the stem) is located on the centerline of the valve body and the sealing surface of the disc section, the disc rotates 90 degrees to complete the opening and closing. Seat made of synthetic rubber. Hongfeng valve that closed the outer surface of the butterfly valve seal extrusion rubber seat, the valve seat to produce elastic deformation and the formation of elastic force as a seal than the pressure to ensure that the butterfly valve seal. D341X flange rubber butterfly valve Features: ★ drive mode can choose manual, electric or pneumatic. ☆ flow characteristics tend to line, adjust the performance. ◆ Seals can be replaced, and sealed to achieve two-way seal. ◇ compact and lightweight, easy disassembly and maintenance, and can be installed in any location. - Simple, compact, low operating torque, 90 ° swivel open quickly. □ butterfly spray coating according to user requirements, such as nylon or PTFE. ▲ disc and valve stem connection pinless structure, to overcome the possible internal leakage point. △ spherical disc spherical shape, improve the sealing performance and extend the life of the valve, open more than 50,000 times with pressure remains zero leakage. ☆ Design and manufacture: GB12238 Structure length: GB12221 (13 series) Flange connection size: GB4216 D41J Semi-lined rubber butterfly valve 【Print】 【Close】
