Steam Pressure Reducing Valve | MIYAWAKI

By: Miyawaki  06-Dec-2011

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.

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.

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.


Steam Trap Management System | MIYAWAKI

PM 15 consisting of the steam trap checker PM 11 and its software SurveyProLight PM 150 help you to increase the efficiency of your steam system substantially. The request for energy conservation makes it more and more necessary to survey steam traps regularly to prevent huge energy losses. MIYAWAKI's testing equipment, especially the computerized Steam Trap Management System "Dr. Trap" PM 301 and "Dr. Trap Jr..



When condensate with higher 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. 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.
