Fully welded ball valve BTW Series Features and benefits：
1.Trunnion mounted ball design.
2.The integral pipe of body is welded by cold-pressing for avoid any leakage.
3.Spring loaded seat could well adapt the change of pressure and temperature,ensure precisely contacting between seat and ball.It makes valves with flexible operation on the basis of good sealing.
4.Ball and stem by precisely machning would reduces the friction coefficient,that ensures good sealing and low torque.
5.Leakage rate “A”, small loading to piping and long service life.
