Metal seal valve plunger

Metal id cable ties valve plunger GB using non-metallic sealing flange connection valve sizes designed drum-shaped plunger valve and drum-shaped metal printed cable ties flange plunger valve handwheel operating mechanism has two forms, one as shown in Figure VI. shown in Figure 8, another new form shown in Figure 7, the rotation of the hstainless steel cable ties not only to cook, only the vertical movement of the stem without rotating motion. When the valve is fully open valve stem elongation to the highest point, but still in the protective jacket.
Advantages of this handwheel operating mechanism is as follows:
A hand Lunbu Shang, the smaller the space occupied by the movement, mounted in a compact space, suitable for piping system.
2, the rotation torque of the hand wheel, not directly on the valve stem, the stem is not easy bending deformation and the rotating torque is small.
3, the stem in a protective case, the next movement from the outside world, piston valve suitable for outdoor installation, avoiding the atmosphere by blowing sand abrasion and acid corrosion of materials.
