Top of the cut-off valve have the following

1) angle globe valve; angle type valve, the fluid simply by changing the direction, so that the passage of the valve pressure drop than the conventional structure of globe valves.pneumatic fitting
 2) DC cut-off valve; in DC or Y-shaped cut-off valve, the valve body of the flow channel and sprue into a slash, the extent of the damage of this flow state is smaller than the conventional cut-off valve, and thus also the pressure loss through the valve small. 3) plunger type valve: This form of cut-off valve is a variant of the conventional valves. In the valve, the valve and seat are usually based on the plunger principle. Valve Polished into a flap connected to the plunger and valve stem seal is achieved by two elastic ring sets on the plunger. Two elastic rings with a collar separated and applied to the valve cover nut load on the valve cover seals around the plunger pressure prison. The elastic sealing ring can be replaced, a variety of materials can be used, the valve is mainly used in the "On" or "Off", but with a special form of a plunger or a special collar, but also can be used to regulate the flow .electric solenoid valve
