Ductile Iron Cut-off Valve SWD-M06
描述
| Size | DN40-DN300 1-1/2″-12″ |
| Working Pressure | PN10/PN16/10K/16K/125LB/150LB |
| Face to face | DIN3202-F1 |
| Flange drilled | EN1092-2 |
| Working environment | Water, Oil, Steam |
| Working temperature | ≦120℃ |
Cut-off Valve Characteristics:
(1) The structure of the cut-off valve is simpler than the gate valve, and it is convenient to manufacture and maintain.
(2) There is no relative sliding between the valve flap and the sealing surface of the valve body during opening and closing, so the wear and abrasion are not serious, the sealing performance is good, and the service life is long.
(3) When opening and closing, the valve flap stroke is small, so the height of the shut-off valve is smaller than that of the gate valve, but the structure length is longer than the gate valve.
(4) The opening and closing torque are large, the opening and closing are more laborious, and the opening and closing time is the principal.
(5) The fluid resistance is large because the medium passage in the valve body is tortuous, the fluid resistance is large, and the power consumption is large.
(6) The valve flap is often eroded when fully open.
Disadvantage:
1. The fluid resistance is large, and the force required for opening and closing is large.
2. It is not suitable for media with particles, high viscosity, and easy coking.
3, poor adjustment performance

Along with every little thing which seems to be building inside this particular subject matter, all your perspectives tend to be very refreshing. However, I am sorry, but I can not give credence to your entire suggestion, all be it exciting none the less. It seems to everyone that your opinions are generally not totally rationalized and in simple fact you are your self not even wholly certain of the assertion. In any event I did take pleasure in reading through it.
