The main products of TWS Valve is butterfly valve include wafer butterfly valve, lug butterfly valve, U tupe butterfly valve and flanged butterfly valve.
Alignment features of lugged body allows easy installation between pipeline flanges. a real installationi cost saving, can be installed in the pipe end. C95400 material has excellent corrosion resistance and can adapt to seawater environment.
Soft seat wafer butterfly valve is soft sleeve type and can separate the body and fluid medium exactly.
Eccentric flanged butterfly valve incorporates a positive retained resilient disc seal and either an integral body seat. The valve has three unique attributes: less weight, more strength and lower torque.
Grooved end butterfly valve is a grooved end bubble tight shutoff butterfly valve with outstanding flow characteristics. The rubber seal is molded onto the ductile iron disc, in order to allow for maximum flow potential.
Wafer butterfly valve with worm gear box. The worm is made of ductile iron QT500-7 with the worm shaft, combined with high-precision processing, has the characteristics of wear resistance and high transmission efficiency.
U type butterfly valve is Wafer pattern with flanges. Correcting holes are made on flange according to standard, easy correcting during the installation.Through-out bolt or one-side bolt used. Easy replacing and maintenance.
Small size, light weight and easy maintenance, the above series of valves can be used as a device to cut-off or regulate the flow in various medium pipes.
