Pneumatic main steam trap control valve feature
Pneumatic main steam trap control valve is suitable for controlling high temperature and high pressure saturated water in the drain systems of main steam and reheat steam pipes in thermal power plants. The tandem type fluid channel is continuously changing the fluid direction, so that fluid velocity is controlled at about 30m/s and cavitation damage is avoided. The throttling part of Pneumatic main steam trap control valve is separable from the sealing face to effectively protect the sealing face. The Pneumatic main steam trap control valve trim surface is subjected to hardening treatment, reaching a hardness of about HRC70. It is featured by good erosion resistance and long service life. The Pneumatic main steam trap control valve can be pneumatically or electrically controlled.
