Low noise pressure reducing or throttle valve - reduces noise by correct geometric proportions of valve details

摘要

The valve body houses the valve head which is attached to the valve rod by the nut and clamps the sealing washer in place. The valve design reduces noise by maintaining the following dimensional relationships. The outside dia. D.a. of the valve head is equal to the outside dia. of the valve seat. The valve seat outside dia. is 1 1/2 times the dia. D.o. of the inlet passage. The radius (R) of the valve seat is approx. equal to the projection of the sealing washer above the surrounding metal surface and also equal to one-tenth of the dia. D.o.
