SCCV-System | MIYAWAKI

On start-up, the bimetal discs are all flat and the valve shaft is up with the valve fully open. Virtually all cold condensate and air are discharged.

As the temperature of the condensate increases, the bimetal discs begin to curve gradually and force the valve shaft and the valve holder to move down.

Most of the condensate is still discharged quickly, since the valve and the holes in the fixed guide on the valve seat are still fully open.

When condensate with higher temperature (near to set temperature) flows in, the bimetal discs are curved even more and , at the same time, the valve shaft moves down and the valve holder closes the holes in the guide partially.

The amount of condensate being discharged is reduced quickly. This prolongs the time that the hot condensate stays near the bimetal discs and the heat of the condensate is transferred to the bimetals much more effectively.

In case of very low condensate flow, the holes in the guide are closed completely by the valve holder and the valve will close precisely in the center of the seat. Normally, the trap is filled with hot condensate and the operation will rest in the state shown in figure 3. Condensate will be discharged continuously.

Steam Pressure Reducing Valve | MIYAWAKI

Movement of the bellows will open or close the pilot valve, regulating the amount of steam influencing the movement of the piston, which will close or open the main valve, thus keeping downstream pressure on a stable level. Changes in downstream pressure are sensed by the pilot valve mechanism (bellows connected with a pilot valve unit) through a signal line D, which connects the pilot valve regulator with the secondary pressure side.

Air Traps | MIYAWAKI

MIYAWAKI Air Traps are designed for continuous discharge of condensate from air piping, receiver tanks, gas and compressed air systems. Most of the traps can be fitted with a pressure - balancing line to ensure air can escape from the trap body to prevent air locking. Depending on the operating conditions and applications a wide range of various types of air traps is available.
